The Adventure of the Bruce-Partington Plans
By Sir Arthur Conan Doyle

In the third week of November, in the year 1895, a dense yellow
fog settled down upon London. From the Monday to the Thursday I
doubt whether it was ever possible from our windows in Baker
Street to see the loom of the opposite houses. The first day
Holmes had spent in cross-indexing his huge book of references.
The second and third had been patiently occupied upon a subject
which he hand recently made his hobby--the music of the Middle
Ages. But when, for the fourth time, after pushing back our
chairs from breakfast we saw the greasy, heavy brown swirl still
drifting past us and condensing in oily drops upon the window-
panes, my comrade's impatient and active nature could endure this
drab existence no longer. He paced restlessly about our sitting-
room in a fever of suppressed energy, biting his nails, tapping
the furniture, and chafing against inaction.

"Nothing of interest in the paper, Watson?" he said.

In was aware that by anything of interest, Holmes meant anything
of criminal interest. There was the news of a revolution, of a
possible war, and of an impending change of government; but these
did not come within the horizon of my companion. I could see
nothing recorded in the shape of crime which was not commonplace
and futile. Holmes groaned and resumed hs restless meanderings.

"The London criminal is certainly a dull fellow," said he in the
querulous voice of the sportsman whose game has failed him.
"Look out this window, Watson. See how the figures loom up, are
dimly seen, and then blend once more into the cloud-bank. The
thief or the murderer could roam London on such a day as the
tiger does the jungle, unseen until he pounces, and then evident
only to his victim."

"There have," said I, "been numerous petty thefts."

Holmes snorted his contempt.

"This great and sombre stage is set for something more worthy
than that," said he. "It is fortunate for this community that I
am not a criminal."

"It is, indeed!" said I heartily.

"Suppose that I were Brooks or Woodhouse, or any of the fifty men
who have good reason for taking my life, how long could I survive
against my own pursuit? A summons, a bogus appointment, and all
would be over. It is well they don't have days of fog in the
Latin countries--the countries of assassination. By Jove! here
comes something at last to break our dead monotony."

It was the maid with a telegram. Holmes tore it open and burst
out laughing.

"Well, well! What next?" said he. "Brother Mycroft is coming

"Why not?" I asked.

"Why not? It is as if you met a tram-car coming down a country
lane. Mycroft has his rails and he runs on them. His Pall Mall
lodgings, the Diogenes Club, Whitehall--that is his cycle. Once,
and only once, he has been here. What upheaval can possibly have
derailed him?"

"Does he not explain?"

Holmes handed me his brother's telegram.

Must see you over Cadogen West. Coming at once.


"Cadogen West? I have heard the name."

"It recalls nothing to my mind. But that Mycroft should break
out in this erratic fashion! A planet might as well leave its
orbit. By the way, do you know what Mycroft is?"

I had some vague recollection of an explanation at the time of
the Adventure of the Greek Interpreter.

"You told me that he had some small office under the British

Holmes chuckled.

"I did not know you quite so well in those days. One has to be
discreet when one talks of high matters of state. You are right
in thinking that he under the British government. You would also
be right in a sense if you said that occasionally he IS the
British government."

"My dear Holmes!"

"I thought I might surprise you. Mycroft draws four hundred and
fifty pounds a year, remains a subordinate, has no ambitions of
any kind, will receive neither honour nor title, but remains the
most indispensable man in the country."

"But how?"

"Well, his position is unique. He has made it for himself.
There has never been anything like it before, nor will be again.
He has the tidiest and most orderly brain, with the greatest
capacity for storing facts, of any man living. The same great
powers which I have turned to the detection of crime he has used
for this particular business. The conclusions of every
department are passed to him, and he is the central exchange, the
clearinghouse, which makes out the balance. All other men are
specialists, but his specialism is omniscience. We will suppose
that a minister needs information as to a point which involves
the Navy, India, Canada and the bimetallic question; he could get
his separate advices from various departments upon each, but only
Mycroft can focus them all, and say offhand how each factor would
affect the other. They began by using him as a short-cut, a
convenience; now he has made himself an essential. In that great
brain of his everything is pigeon-holed and can be handed out in
an instant. Again and again his word has decided the national
policy. He lives in it. He thinks of nothing else save when, as
an intellectual exercise, he unbends if I call upon him and ask
him to advise me on one of my little problems. But Jupiter is
descending to-day. What on earth can it mean? Who is Cadogan
West, and what is he to Mycroft?"

"I have it," I cried, and plunged among the litter of papers upon
the sofa. "Yes, yes, here he is, sure enough! Cadogen West was
the young man who was found dead on the Underground on Tuesday

Holmes sat up at attention, his pipe halfway to his lips.

"This must be serious, Watson. A death which has caused my
brother to alter his habits can be no ordinary one. What in the
world can he have to do with it? The case was featureless as I
remember it. The young man had apparently fallen out of the
train and killed himself. He had not been robbed, and there was
no particular reason to suspect violence. Is that not so?"

"There has been an inquest," said I, "and a good many fresh facts
have come out. Looked at more closely, I should certainly say
that it was a curious case."

"Judging by its effect upon my brother, I should think it must be
a most extraordinary one." He snuggled down in his armchair.
"Now, Watson, let us have the facts."

"The man's name was Arthur Cadogan West. He was twenty-seven
years of age, unmarried, and a clerk at Woolwich Arsenal."

"Government employ. Behold the link with Brother Mycroft!"

"He left Woolwich suddenly on Monday night. Was last seen by his
fiancee, Miss Violet Westbury, whom he left abruptly in the fog
about 7:30 that evening. There was no quarrel between them and
she can give no motive for his action. The next thing heard of
him was when his dead body was discovered by a plate-layer named
Mason, just outside Aldgate Station on the Underground system in


"The body was found at six on Tuesday morning. It was lying wide
of the metals upon the left hand of the track as one goes
eastward, at a point close to the station, where the line emerges
from the tunnel in which it runs. The head was badly crushed--an
injury which might well have been caused by a fall from the
train. The body could only have come on the line in that way.
Had it been carried down from any neighbouring street, it must
have passed the station barriers, where a collector is always
standing. This point seems absolutely certain."

"Very good. The case is definite enough. The man, dead or
alive, either fell or was precipitated from a train. So much is
clear to me. Continue."

"The trains which traverse the lines of rail beside which the
body was found are those which run from west to east, some being
purely Metropolitan, and some from Willesden and outlying
junctions. It can be stated for certain that this young man,
when he met his death, was travelling in this direction at some
late hour of the night, but at what point he entered the train it
is impossible to state."

"His ticket, of course, would show that."

"There was no ticket in his pockets."

"No ticket! Dear me, Watson, this is really very singular.
According to my experience it is not possible to reach the
platform of a Metropolitan train without exhibiting one's ticket.
Presumably, then, the young man had one. Was it taken from him
in order to conceal the station from which he came? It is
possible. Or did he drop it in the carriage? That is also
possible. But the point is of curious interest. I understand
that there was no sign of robbery?"

"Apparently not. There is a list here of his possessions. His
purse contained two pounds fifteen. He had also a check-book on
the Woolwich branch of the Capital and Counties Bank. Through
this his identity was established. There were also two dress-
circle tickets for the Woolwich Theatre, dated for that very
evening. Also a small packet of technical papers."

Holmes gave an exclamation of satisfaction.

"There we have it at last, Watson! British government--Woolwich.
Arsenal--technical papers--Brother Mycroft, the chain is
complete. But here he comes, if I am not mistaken, to speak for

A moment later the tall and portly form of Mycroft Holmes was
ushered into the room. Heavily built and massive, there was a
suggestion of uncouth physical inertia in the figure, but above
this unwieldy frame there was perched a head so masterful in its
brow, so alert in its steel-gray, deep-set eyes, so firm in its
lips, and so subtle in its play of expression, that after the
first glance one forgot the gross body and remembered only the
dominant mind.

At his heels came our old friend Lestrade, of Scotland Yard--thin
and austere. The gravity of both their faces foretold some
weighty quest. The detective shook hands without a word.
Mycroft Holmes struggled out of his overcoat and subsided into an

"A most annoying business, Sherlock," said he. "I extremely
dislike altering my habits, but the powers that be would take no
denial. In the present state of Siam it is most awkward that I
should be away from the office. But it is a real crisis. I have
never seen the Prime Minister so upset. As to the Admiralty--it
is buzzing like an overturned bee-hive. Have you read up the

"We have just done so. What were the technical papers?"

"Ah, there's the point! Fortunately, it has not come out. The
press would be furious if it did. The papers which this wretched
youth had in his pocket were the plans of the Bruce-Partington

Mycroft Holmes spoke with a solemnity which showed his sense of
the importance of the subject. His brother and I sat expectant.

"Surely you have heard of it? I thought everyone had heard of

"Only as a name."

"Its importance can hardly be exaggerated. It has been the most
jealously guarded of all government secrets. You may take it
from me that naval warfare becomes impossible withing the radius
of a Bruce-Partington's operation. Two years ago a very large
sum was smuggled through the Estimates and was expended in
acquiring a monopoly of the invention. Every effort has been
made to keep the secret. The plans, which are exceedingly
intricate, comprising some thirty separate patents, each
essential to the working of the whole, are kept in an elaborate
safe in a confidential office adjoining the arsenal, with
burglar-proof doors and windows. Under no conceivable
circumstances were the plans to be taken from the office. If the
chief constructor of the Navy desired to consult them, even he
was forced to go to the Woolwich office for the purpose. And yet
here we find them in the pocket of a dead junior clerk in the
heart of London. From an official point of view it's simply

"But you have recovered them?"

"No, Sherlock, no! That's the pinch. We have not. Ten papers
were taken from Woolwich. There were seven in the pocket of
Cadogan West. The three most essential are gone--stolen,
vanished. You must drop everything, Sherlock. Never mind your
usual petty puzzles of the police-court. It's a vital
international problem that you have to solve. Why did Cadogan
West take the papers, where are the missing ones, how did he die,
how came his body where it was found, how can the evil be set
right? Find an answer to all these questions, and you will have
done good service for your country."

"Why do you not solve it yourself, Mycroft? You can see as far
as I."

"Possibly, Sherlock. But it is a question of getting details.
Give me your details, and from an armchair I will return you an
excellent expert opinion. But to run here and run there, to
cross-question railway guards, and lie on my face with a lens to
my eye--it is not my metier. No, you are the one man who can
clear the matter up. If you have a fancy to see your name in the
next honours list--"

My friend smiled and shook his head.

"I play the game for the game's own sake," said he. "But the
problem certainly presents some points of interest, and I shall
be very pleased to look into it. Some more facts, please."

"I have jotted down the more essential ones upon this sheet of
paper, together with a few addresses which you will find of
service. The actual official guardian of the papers is the
famous government expert, Sir James Walter, whose decorations and
sub-titles fill two lines of a book of reference. He has grown
gray in the service, is a gentleman, a favoured guest in the most
exalted houses, and, above all, a man whose patriotism is beyond
suspicion. He is one of two who have a key of the safe. I may
add that the papers were undoubtedly in the office during working
hours on Monday, and that Sir James left for London about three
o'clock taking his key with him. He was at the house of Admiral
Sinclair at Barclay Square during the whole of the evening when
this incident occurred."

"Has the fact been verified?"

"Yes; his brother, Colonel Valentine Walter, has testified to his
departure from Woolwich, and Admiral Sinclair to his arrival in
London; so Sir James is no longer a direct factor in the

"Who was the other man with a key?"

"The senior clerk and draughtsman, Mr. Sidney Johnson. He is a
man of forty, married, with five children. He is a silent,
morose man, but he has, on the whole, an excellent record in the
public service. He is unpopular with his colleagues, but a hard
worker. According to his own account, corroborated only by the
word of his wife, he was at home the whole of Monday evening
after office hours, and his key has never left the watch-chain
upon which it hangs."

"Tell us about Cadogan West."

"He has been ten years in the service and has done good work. He
has the reputation of being hot-headed and imperious, but a
straight, honest man. We have nothing against him. He was next
Sidney Johnson in the office. His duties brought him into daily,
personal contact with the plans. No one else had the handling of

"Who locked up the plans that night?"

"Mr. Sidney Johnson, the senior clerk."

"Well, it is surely perfectly clear who took them away. They are
actually found upon the person of this junior clerk, Cadogan
West. That seems final, does it not?"

"It does, Sherlock, and yet it leaves so much unexplained. In
the first place, why did he take them?"

"I presume they were of value?"

"He could have got several thousands for them very easily."

"Can you suggest any possible motive for taking the papers to
London except to sell them?"

"No, I cannot."

"Then we must take that as our working hypothesis. Young West
took the papers. Now this could only be done by having a false

"Several false keys. He had to open the building and the room."

"He had, then, several false keys. He took the papers to London
to sell the secret, intending, no doubt, to have the plans
themselves back in the safe next morning before they were missed.
While in London on this treasonable mission he met his end."


"We will suppose that he was travelling back to Woolwich when he
was killed and thrown out of the compartment."

"Aldgate, where the body was found, is considerably past the
station London Bridge, which would be his route to Woolwich."

"Many circumstances could be imagined under which he would pass
London Bridge. There was someone in the carriage, for example,
with whom he was having an absorbing interview. This interview
led to a violent scene in which he lost his life. Possibly he
tried to leave the carriage, fell out on the line, and so met his
end. The other closed the door. There was a thick fog, and
nothing could be seen."

"No better explanation can be given with our present knowledge;
and yet consider, Sherlock, how much you leave untouched. We
will suppose, for argument's sake, that young Cadogan West HAD
determined to convey these papers to London. He would naturally
have made an appointment with the foreign agent and kept his
evening clear. Instead of that he took two tickets for the
theatre, escorted his fiancee halfway there, and then suddenly

"A blind," said Lestrade, who had sat listening with some
impatience to the conversation.

"A very singular one. That is objection No. 1. Objection No. 2:
We will suppose that he reaches London and sees the foreign
agent. He must bring back the papers before morning or the loss
will be discovered. He took away ten. Only seven were in his
pocket. What had become of the other three? He certainly would
not leave them of his own free will. Then, again, where is the
price of his treason? Once would have expected to find a large
sum of money in his pocket."

"It seems to me perfectly clear," said Lestrade. "I have no
doubt at all as to what occurred. He took the papers to sell
them. He saw the agent. They could not agree as to price. He
started home again, but the agent went with him. In the train
the agent murdered him, took the more essential papers, and threw
his body from the carriage. That would account for everything,
would it not?"

"Why had he no ticket?"

"The ticket would have shown which station was nearest the
agent's house. Therefore he took it from the murdered man's

"Good, Lestrade, very good," said Holmes. "Your theory holds
together. But if this is true, then the case is at an end. On
the one hand, the traitor is dead. On the other, the plans of
the Bruce-Partington submarine are presumably already on the
Continent. What is there for us to do?"

"To act, Sherlock--to act!" cried Mycroft, springing to his feet.
"All my instincts are against this explanation. Use your powers!
Go to the scene of the crime! See the people concerned! Leave
no stone unturned! In all your career you have never had so
great a chance of serving your country."

"Well, well!" said Holmes, shrugging his shoulders. "Come,
Watson! And you, Lestrade, could you favour us with your company
for an hour or two? We will begin our investigation by a visit
to Aldgate Station. Good-bye, Mycroft. I shall let you have a
report before evening, but I warn you in advance that you have
little to expect."

An hour later Holmes, Lestrade and I stood upon the Underground
railroad at the point where it emerges from the tunnel
immediately before Aldgate Station. A courteous red-faced old
gentleman represented the railway company.

"This is where the young man's body lay," said he, indicating a
spot about three feet from the metals. "It could not have fallen
from above, for these, as you see, are all blank walls.
Therefore, it could only have come from a train, and that train,
so far as we can trace it, must have passed about midnight on

"Have the carriages been examined for any sign of violence?"

"There are no such signs, and no ticket has been found."

"No record of a door being found open?"


"We have had some fresh evidence this morning," said Lestrade.
"A passenger who passed Aldgate in an ordinary Metropolitan train
about 11:40 on Monday night declares that he heard a heavy thud,
as of a body striking the line, just before the train reached the
station. There was dense fog, however, and nothing could be
seen. He made no report of it at the time. Why, whatever is the
matter with Mr. Holmes?"

My friend was standing with an expression of strained intensity
upon his face, staring at the railway metals where they curved
out of the tunnel. Aldgate is a junction, and there was a
network of points. On these his eager, questioning eyes were
fixed, and I saw on his keen, alert face that tightening of the
lips, that quiver of the nostrils, and concentration of the
heavy, tufted brows which I knew so well.

"Points," he muttered; "the points."

"What of it? What do you mean?"

"I suppose there are no great number of points on a system such
as this?"

"No; they are very few."

"And a curve, too. Points, and a curve. By Jove! if it were
only so."

"What is it, Mr. Holmes? Have you a clue?"

"An idea--an indication, no more. But the case certainly grows
in interest. Unique, perfectly unique, and yet why not? I do
not see any indications of bleeding on the line."

"There were hardly any."

"But I understand that there was a considerable wound."

"The bone was crushed, but there was no great external injury."

"And yet one would have expected some bleeding. Would it be
possible for me to inspect the train which contained the
passenger who heard the thud of a fall in the fog?"

"I fear not, Mr. Holmes. The train has been broken up before
now, and the carriages redistributed."

"I can assure you, Mr. Holmes," said Lestrade, "that every
carriage has been carefully examined. I saw to it myself."

It was one of my friend's most obvious weaknesses that he was
impatient with less alert intelligences than his own.

"Very likely," said he, turning away. "As it happens, it was not
the carriages which I desired to examine. Watson, we have done
all we can here. We need not trouble you any further, Mr.
Lestrade. I think our investigations must now carry us to

At London Bridge, Holmes wrote a telegram to his brother, which
he handed to me before dispatching it. It ran thus:

See some light in the darkness, but it may possibly flicker out.
Meanwhile, please send by messenger, to await return at Baker
Street, a complete list of all foreign spies or international
agents known to be in England, with full address.


"That should be helpful, Watson," he remarked as we took our
seats in the Woolwich train. "We certainly owe Brother Mycroft a
debt for having introduced us to what promises to be a really
very remarkable case."

His eager face still wore that expression of intense and high-
strung energy, which showed me that some novel and suggestive
circumstance had opened up a stimulating line of thought. See
the foxhound with hanging ears and drooping tail as it lolls
about the kennels, and compare it with the same hound as, with
gleaming eyes and straining muscles, it runs upon a breast-high
scent--such was the change in Holmes since the morning. He was a
different man from the limp and lounging figure in the mouse-
coloured dressing-gown who had prowled so restlessly only a few
hours before round the fog-girt room.

"There is material here. There is scope," said he. "I am dull
indeed not to have understood its possibilities."

"Even now they are dark to me."

"The end is dark to me also, but I have hold of one idea which
may lead us far. The man met his death elsewhere, and his body
was on the ROOF of a carriage."

"On the roof!"

"Remarkable, is it not? But consider the facts. Is it a
coincidence that it is found at the very point where the train
pitches and sways as it comes round on the points? Is not that
the place where an object upon the roof might be expected to fall
off? The points would affect no object inside the train. Either
the body fell from the roof, or a very curious coincidence has
occurred. But now consider the question of the blood. Of
course, there was no bleeding on the line if the body had bled
elsewhere. Each fact is suggestive in itself. Together they
have a cumulative force."

"And the ticket, too!" I cried.

"Exactly. We could not explain the absence of a ticket. This
would explain it. Everything fits together."

"But suppose it were so, we are still as far as ever from
unravelling the mystery of his death. Indeed, it becomes not
simpler but stranger."

"Perhaps," said Holmes, thoughtfully, "perhaps." He relapsed
into a silent reverie, which lasted until the slow train drew up
at last in Woolwich Station. There he called a cab and drew
Mycroft's paper from his pocket.

"We have quite a little round of afternoon calls to make," said
he. "I think that Sir James Walter claims our first attention."

The house of the famous official was a fine villa with green
lawns stretching down to the Thames. As we reached it the fog
was lifting, and a thin, watery sunshine was breaking through. A
butler answered our ring.

"Sir James, sir!" said he with solemn face. "Sir James died this

"Good heavens!" cried Holmes in amazement. "How did he die?"

"Perhaps you would care to step in, sir, and see his brother,
Colonel Valentine?"

"Yes, we had best do so."

We were ushered into a dim-lit drawing-room, where an instant
later we were joined by a very tall, handsome, light-beared man
of fifty, the younger brother of the dead scientist. His wild
eyes, stained cheeks, and unkempt hair all spoke of the sudden
blow which had fallen upon the household. He was hardly
articulate as he spoke of it.

"It was this horrible scandal," said he. "My brother, Sir James,
was a man of very sensitive honour, and he could not survive such
an affair. It broke his heart. He was always so proud of the
efficiency of his department, and this was a crushing blow."

"We had hoped that he might have given us some indications which
would have helped us to clear the matter up."

"I assure you that it was all a mystery to him as it is to you
and to all of us. He had already put all his knowledge at the
disposal of the police. Naturally he had no doubt that Cadogan
West was guilty. But all the rest was inconceivable."

"You cannot throw any new light upon the affair?"

"I know nothing myself save what I have read or heard. I have no
desire to be discourteous, but you can understand, Mr. Holmes,
that we are much disturbed at present, and I must ask you to
hasten this interview to an end."

"This is indeed an unexpected development," said my friend when
we had regained the cab. "I wonder if the death was natural, or
whether the poor old fellow killed himself! If the latter, may
it be taken as some sign of self-reproach for duty neglected? We
must leave that question to the future. Now we shall turn to the
Cadogan Wests."

A small but well-kept house in the outskirts of the town
sheltered the bereaved mother. The old lady was too dazed with
grief to be of any use to us, but at her side was a white-faced
young lady, who introduced herself as Miss Violet Westbury, the
fiancee of the dead man, and the last to see him upon that fatal

"I cannot explain it, Mr. Holmes," she said. "I have not shut an
eye since the tragedy, thinking, thinking, thinking, night and
day, what the true meaning of it can be. Arthur was the most
single-minded, chivalrous, patriotic man upon earth. He would
have cut his right hand off before he would sell a State secret
confided to his keeping. It is absurd, impossible, preposterous
to anyone who knew him."

"But the facts, Miss Westbury?"

"Yes, yes; I admit I cannot explain them."

"Was he in any want of money?"

"No; his needs were very simple and his salary ample. He had
saved a few hundreds, and we were to marry at the New Year."

"No signs of any mental excitement? Come, Miss Westbury, be
absolutely frank with us."

The quick eye of my companion had noted some change in her
manner. She coloured and hesitated.

"Yes," she said at last, "I had a feeling that there was
something on his mind."

"For long?"

"Only for the last week or so. He was thoughtful and worried.
Once I pressed him about it. He admitted that there was
something, and that it was concerned with his official life. 'It
is too serious for me to speak about, even to you,' said he. I
could get nothing more."

Holmes looked grave.

"Go on, Miss Westbury. Even if it seems to tell against him, go
on. We cannot say what it may lead to."

"Indeed, I have nothing more to tell. Once or twice it seemed to
me that he was on the point of telling me something. He spoke
one evening of the importance of the secret, and I have some
recollection that he said that no doubt foreign spies would pay a
great deal to have it."

My friend's face grew graver still.

"Anything else?"

"He said that we were slack about such matters--that it would be
easy for a traitor to get the plans."

"Was it only recently that he made such remarks?"

"Yes, quite recently."

"Now tell us of that last evening."

"We were to go to the theatre. The fog was so thick that a cab
was useless. We walked, and our way took us close to the office.
Suddenly he darted away into the fog."

"Without a word?"

"He gave an exclamation; that was all. I waited but he never
returned. Then I walked home. Next morning, after the office
opened, they came to inquire. About twelve o'clock we heard the
terrible news. Oh, Mr. Holmes, if you could only, only save his
honour! It was so much to him."

Holmes shook his head sadly.

"Come, Watson," said he, "our ways lie elsewhere. Our next
station must be the office from which the papers were taken.

"It was black enough before against this young man, but our
inquiries make it blacker," he remarked as the cab lumbered off.
"His coming marriage gives a motive for the crime. He naturally
wanted money. The idea was in his head, since he spoke about it.
He nearly made the girl an accomplice in the treason by telling
her his plans. It is all very bad."

"But surely, Holmes, character goes for something? Then, again,
why should he leave the girl in the street and dart away to
commit a felony?"

"Exactly! There are certainly objections. But it is a
formidable case which they have to meet."

Mr. Sidney Johnson, the senior clerk, met us at the office and
received us with that respect which my companion's card always
commanded. He was a thin, gruff, bespectacled man of middle age,
his cheeks haggard, and his hands twitching from the nervous
strain to which he had been subjected.

"It is bad, Mr. Holmes, very bad! Have you heard of the death of
the chief?"

"We have just come from his house."

"The place is disorganized. The chief dead, Cadogan West dead,
our papers stolen. And yet, when we closed our door on Monday
evening, we were as efficient an office as any in the government
service. Good God, it's dreadful to think of! That West, of all
men, should have done such a thing!"

"You are sure of his guilt, then?"

"I can see no other way out of it. And yet I would have trusted
him as I trust myself."

"At what hour was the office closed on Monday?"

"At five."

"Did you close it?"

"I am always the last man out."

"Where were the plans?"

"In that safe. I put them there myself."

"Is there no watchman to the building?"

"There is, but he has other departments to look after as well.
He is an old soldier and a most trustworthy man. He saw nothing
that evening. Of course the fog was very thick."

"Suppose that Cadogan West wished to make his way into the
building after hours; he would need three keys, would he not,
before the could reach the papers?"

"Yes, he would. The key of the outer door, the key of the
office, and the key of the safe."

"Only Sir James Walter and you had those keys?"

"I had no keys of the doors--only of the safe."

"Was Sir James a man who was orderly in his habits?"

"Yes, I think he was. I know that so far as those three keys are
concerned he kept them on the same ring. I have often seen them

"And that ring went with him to London?"

"He said so."

"And your key never left your possession?"


"Then West, if he is the culprit, must have had a duplicate. And
yet none was found upon his body. One other point: if a clerk
in this office desired to sell the plans, would it not be simply
to copy the plans for himself than to take the originals, as was
actually done?"

"It would take considerable technical knowledge to copy the plans
in an effective way."

"But I suppose either Sir James, or you, or West has that
technical knowledge?"

"No doubt we had, but I beg you won't try to drag me into the
matter, Mr. Holmes. What is the use of our speculating in this
way when the original plans were actually found on West?"

"Well, it is certainly singular that he should run the risk of
taking originals if he could safely have taken copies, which
would have equally served his turn."

"Singular, no doubt--and yet he did so."

"Every inquiry in this case reveals something inexplicable. Now
there are three papers still missing. They are, as I understand,
the vital ones."

"Yes, that is so."

"Do you mean to say that anyone holding these three papers, and
without the seven others, could construct a Bruce-Partington

"I reported to that effect to the Admiralty. But to-day I have
been over the drawings again, and I am not so sure of it. The
double valves with the automatic self-adjusting slots are drawn
in one of the papers which have been returned. Until the
foreigners had invented that for themselves they could not make
the boat. Of course they might soon get over the difficulty."

"But the three missing drawings are the most important?"


"I think, with your permission, I will now take a stroll round
the premises. I do not recall any other question which I desired
to ask."

He examined the lock of the safe, the door of the room, and
finally the iron shutters of the window. It was only when we
were on the lawn outside that his interest was strongly excited.
There was a laurel bush outside the window, and several of the
branches bore signs of having been twisted or snapped. He
examined them carefully with his lens, and then some dim and
vague marks upon the earth beneath. Finally he asked the chief
clerk to close the iron shutters, and he pointed out to me that
they hardly met in the centre, and that it would be possible for
anyone outside to see what was going on within the room.

"The indications are ruined by three days' delay. They may mean
something or nothing. Well, Watson, I do not think that Woolwich
can help us further. It is a small crop which we have gathered.
Let us see if we can do better in London."

Yet we added one more sheaf to our harvest before we left
Woolwich Station. The clerk in the ticket office was able to say
with confidence that he saw Cadogan West--whom he knew well by
sight--upon the Monday night, and that he went to London by the
8:15 to London Bridge. He was alone and took a single third-
class ticket. The clerk was struck at the time by his excited
and nervous manner. So shaky was he that he could hardly pick up
his change, and the clerk had helped him with it. A reference to
the timetable showed that the 8:15 was the first train which it
was possible for West to take after he had left the lady about

"Let us reconstruct, Watson," said Holmes after half an hour of
silence. "I am not aware that in all our joint researches we
have ever had a case which was more difficult to get at. Every
fresh advance which we make only reveals a fresh ridge beyond.
And yet we have surely made some appreciable progress.

"The effect of our inquiries at Woolwich has in the main been
against young Cadogan West; but the indications at the window
would lend themselves to a more favourable hypothesis. Let us
suppose, for example, that he had been approached by some foreign
agent. It might have been done under such pledges as would have
prevented him from speaking of it, and yet would have affected
his thoughts in the direction indicated by his remarks to his
fiancee. Very good. We will now suppose that as he went to the
theatre with the young lady he suddenly, in the fog, caught a
glimpse of this same agent going in the direction of the office.
He was an impetuous man, quick in his decisions. Everything gave
way to his duty. He followed the man, reached the window, saw
the abstraction of the documents, and pursued the thief. In this
way we get over the objection that no one would take originals
when he could make copies. This outsider had to take originals.
So far it holds together."

"What is the next step?"

"Then we come into difficulties. One would imagine that under
such circumstances the first act of young Cadogan West would be
to seize the villain and raise the alarm. Why did he not do so?
Could it have been an official superior who took the papers?
That would explain West's conduct. Or could the chief have given
West the slip in the fog, and West started at once to London to
head him off from his own rooms, presuming that he knew where the
rooms were? The call must have been very pressing, since he left
his girl standing in the fog and made no effort to communicate
with her. Our scent runs cold here, and there is a vast gap
between either hypothesis and the laying of West's body, with
seven papers in his pocket, on the roof of a Metropolitan train.
My instinct now is to work form the other end. If Mycroft has
given us the list of addresses we may be able to pick our man and
follow two tracks instead of one."

Surely enough, a note awaited us at Baker Street. A government
messenger had brought it post-haste. Holmes glanced at it and
threw it over to me.

There are numerous small fry, but few who would handle so big an
affair. The only men worth considering are Adolph Mayer, of 13
Great George Street, Westminster; Louis La Rothiere, of Campden
Mansions, Notting Hill; and Hugo Oberstein, 13 Caulfield Gardens,
Kensington. The latter was known to be in town on Monday and is
now reported as having left. Glad to hear you have seen some
light. The Cabinet awaits your final report with the utmost
anxiety. Urgent representations have arrived from the very
highest quarter. The whole force of the State is at your back if
you should need it.


"I'm afraid," said Holmes, smiling, "that all the queen's horses
and all the queen's men cannot avail in this matter." He had
spread out his big map of London and leaned eagerly over it.
"Well, well," said he presently with an exclamation of
satisfaction, "things are turning a little in our direction at
last. Why, Watson, I do honestly believe that we are going to
pull it off, after all." He slapped me on the shoulder with a
sudden burst of hilarity. "I am going out now. It is only a
reconnaissance. I will do nothing serious without my trusted
comrade and biographer at my elbow. Do you stay here, and the
odds are that you will see me again in an hour or two. If time
hangs heavy get foolscap and a pen, and begin your narrative of
how we saved the State."

I felt some reflection of his elation in my own mind, for I knew
well that he would not depart so far from his usual austerity of
demeanour unless there was good cause for exultation. All the
long November evening I waited, filled with impatience for his
return. At last, shortly after nine o'clock, there arrived a
messenger with a note:

Am dining at Goldini's Restaurant, Gloucester Road, Kensington.
Please come at once and join me there. Bring with you a jemmy, a
dark lantern, a chisel, and a revolver.


It was a nice equipment for a respectable citizen to carry
through the dim, fog-draped streets. I stowed them all
discreetly away in my overcoat and drove straight to the address
given. There sat my friend at a little round table near the door
of the garish Italian restaurant.

"Have you had something to eat? Then join me in a coffee and
curacao. Try one of the proprietor's cigars. They are less
poisonous than one would expect. Have you the tools?"

"They are here, in my overcoat."

"Excellent. Let me give you a short sketch of what I have done,
with some indication of what we are about to do. Now it must be
evident to you, Watson, that this young man's body was PLACED on
the roof of the train. That was clear from the instant that I
determined the fact that it was from the roof, and not from a
carriage, that he had fallen."

"Could it not have been dropped from a bridge?"

"I should say it was impossible. If you examine the roofs you
will find that they are slightly rounded, and there is no railing
round them. Therefore, we can say for certain that young Cadogan
West was placed on it."

"How could he be placed there?"

"That was the question which we had to answer. There is only one
possible way. You are aware that the Underground runs clear of
tunnels at some points in the West End. I had a vague memory
that as I have travelled by it I have occasionally seen windows
just above my head. Now, suppose that a train halted under such
a window, would there be any difficulty in laying a body upon the

"It seems most improbable."

"We must fall back upon the old axiom that when all other
contingencies fail, whatever remains, however improbable, must be
the truth. Here all other contingencies HAVE failed. When I
found that the leading international agent, who had just left
London, lived in a row of houses which abutted upon the
Underground, I was so pleased that you were a little astonished
at my sudden frivolity."

"Oh, that was it, was it?"

"Yes, that was it. Mr. Hugo Oberstein, of 13 Caulfield Gardens,
had become my objective. I began my operations at Gloucester
Road Station, where a very helpful official walked with me along
the track and allowed me to satisfy myself not only that the
back-stair windows of Caulfield Gardens open on the line but the
even more essential fact that, owing to the intersection of one
of the larger railways, the Underground trains are frequently
held motionless for some minutes at that very spot."

"Splendid, Holmes! You have got it!"

"So far--so far, Watson. We advance, but the goal is afar.
Well, having seen the back of Caulfield Gardens, I visited the
front and satisfied myself that the bird was indeed flown. It is
a considerable house, unfurnished, so far as I could judge, in
the upper rooms. Oberstein lived there with a single valet, who
was probably a confederate entirely in his confidence. We must
bear in mind that Oberstein has gone to the Continent to dispose
of his booty, but not with any idea of flight; for he had no
reason to fear a warrant, and the idea of an amateur domiciliary
visit would certainly never occur to him. Yet that is precisely
what we are about to make."

"Could we not get a warrant and legalize it?"

"Hardly on the evidence."

"What can we hope to do?"

"We cannot tell what correspondence may be there."

"I don't like it, Holmes."

"My dear fellow, you shall keep watch in the street. I'll do the
criminal part. It's not a time to stick at trifles. Think of
Mycroft's note, of the Admiralty, the Cabinet, the exalted person
who waits for news. We are bound to go."

My answer was to rise from the table.

"You are right, Holmes. We are bound to go."

He sprang up and shook me by the hand.

"I knew you would not shrink at the last," said he, and for a
moment I saw something in his eyes which was nearer to tenderness
than I had ever seen. The next instant he was his masterful,
practical self once more.

"It is nearly half a mile, but there is no hurry. Let us walk,"
said he. "Don't drop the instruments, I beg. Your arrest as a
suspicious character would be a most unfortunate complication."

Caulfield Gardens was one of those lines of flat-faced pillared,
and porticoed houses which are so prominent a product of the
middle Victorian epoch in the West End of London. Next door
there appeared to be a children's party, for the merry buzz of
young voices and the clatter of a piano resounded through the
night. The fog still hung about and screened us with its
friendly shade. Holmes had lit his lantern and flashed it upon
the massive door.

"This is a serious proposition," said he. "It is certainly
bolted as well as locked. We would do better in the area. There
is an excellent archway down yonder in case a too zealous
policeman should intrude. Give me a hand, Watson, and I'll do
the same for you."

A minute later we were both in the area. Hardly had we reached
the dark shadows before the step of the policeman was heard in
the fog above. As its soft rhythm died away, Holmes set to work
upon the lower door. I saw him stoop and strain until with a
sharp crash it flew open. We sprang through into the dark
passage, closing the area door behind us. Holmes let the way up
the curving, uncarpeted stair. His little fan of yellow light
shone upon a low window.

"Here we are, Watson--this must be the one." He threw it open,
and as he did so there was a low, harsh murmur, growing steadily
into a loud roar as a train dashed past us in the darkness.
Holmes swept his light along the window-sill. It was thickly
coated with soot from the passing engines, but the black surface
was blurred and rubbed in places.

"You can see where they rested the body. Halloa, Watson! what is
this? There can be no doubt that it is a blood mark." He was
pointing to faint discolourations along the woodwork of the
window. "Here it is on the stone of the stair also. The
demonstration is complete. Let us stay here until a train

We had not long to wait. The very next train roared from the
tunnel as before, but slowed in the open, and then, with a
creaking of brakes, pulled up immediately beneath us. It was not
four feet from the window-ledge to the roof of the carriages.
Holmes softly closed the window.

"So far we are justified," said he. "What do you think of it,

"A masterpiece. You have never risen to a greater height."

"I cannot agree with you there. From the moment that I conceived
the idea of the body being upon the roof, which surely was not a
very abstruse one, all the rest was inevitable. If it were not
for the grave interests involved the affair up to this point
would be insignificant. Our difficulties are still before us.
But perhaps we may find something here which may help us."

We had ascended the kitchen stair and entered the suite of rooms
upon the first floor. One was a dining-room, severely furnished
and containing nothing of interest. A second was a bedroom,
which also drew blank. The remaining room appeared more
promising, and my companion settled down to a systematic
examination. It was littered with books and papers, and was
evidently used as a study. Swiftly and methodically Holmes
turned over the contents of drawer after drawer and cupboard
after cupboard, but no gleam of success came to brighten his
austere face. At the end of an hour he was no further than when
he started.

"The cunning dog has covered his tracks," said he. "He has left
nothing to incriminate him. His dangerous correspondence has
been destroyed or removed. This is our last chance."

It was a small tin cash-box which stood upon the writing-desk.
Holmes pried it open with his chisel. Several rolls of paper
were within, covered with figures and calculations, without any
note to show to what they referred. The recurring words, "water
pressure" and "pressure to the square inch" suggested some
possible relation to a submarine. Holmes tossed them all
impatiently aside. There only remained an envelope with some
small newspaper slips inside it. He shook them out on the table,
and at once I saw by his eager face that his hopes had been

"What's this, Watson? Eh? What's this? Record of a series of
messages in the advertisements of a paper. Daily Telegraph agony
column by the print and paper. Right-hand top corner of a page.
No dates--but messages arrange themselves. This must be the

"Hoped to hear sooner. Terms agreed to. Write fully to address
given on card.


"Next comes:

"Too complex for description. Must have full report, Stuff
awaits you when goods delivered.


"Then comes:

"Matter presses. Must withdraw offer unless contract completed.
Make appointment by letter. Will confirm by advertisement.



"Monday night after nine. Two taps. Only ourselves. Do not be
so suspicious. Payment in hard cash when goods delivered.


"A fairly complete record, Watson! If we could only get at the
man at the other end!" He sat lost in thought, tapping his
fingers on the table. Finally he sprang to his feet.

"Well, perhaps it won't be so difficult, after all. There is
nothing more to be done here, Watson. I think we might drive
round to the offices of the Daily Telegraph, and so bring a good
day's work to a conclusion."

Mycroft Holmes and Lestrade had come round by appointment after
breakfast next day and Sherlock Holmes had recounted to them our
proceedings of the day before. The professional shook his head
over our confessed burglary.

"We can't do these things in the force, Mr. Holmes," said he.
"No wonder you get results that are beyond us. But some of these
days you'll go too far, and you'll find yourself and your friend
in trouble."

"For England, home and beauty--eh, Watson? Martyrs on the altar
of our country. But what do you think of it, Mycroft?"

"Excellent, Sherlock! Admirable! But what use will you make of

Holmes picked up the Daily Telegraph which lay upon the table.

"Have you seen Pierrot's advertisement to-day?"

"What? Another one?"

"Yes, here it is:

"To-night. Same hour. Same place. Two taps. Most vitally
important. Your own safety at stake.


"By George!" cried Lestrade. "If he answers that we've got him!"

"That was my idea when I put it in. I think if you could both
make it convenient to come with us about eight o'clock to
Caulfield Gardens we might possibly get a little nearer to a

One of the most remarkable characteristics of Sherlock Holmes was
his power of throwing his brain out of action and switching all
his thoughts on to lighter things whenever he had convinced
himself that he could no longer work to advantage. I remember
that during the whole of that memorable day he lost himself in a
monograph which he had undertaken upon the Polyphonic Motets of
Lassus. For my own part I had none of this power of detachment,
and the day, in consequence, appeared to be interminable. The
great national importance of the issue, the suspense in high
quarters, the direct nature of the experiment which we were
trying--all combined to work upon my nerve. It was a relief to
me when at last, after a light dinner, we set out upon our
expedition. Lestrade and Mycroft met us by appointment at the
outside of Gloucester Road Station. The area door of Oberstein's
house had been left open the night before, and it was necessary
for me, as Mycroft Holmes absolutely and indignantly declined to
climb the railings, to pass in and open the hall door. By nine
o'clock we were all seated in the study, waiting patently for our

An hour passed and yet another. When eleven struck, the measured
beat of the great church clock seemed to sound the dirge of our
hopes. Lestrade and Mycroft were fidgeting in their seats and
looking twice a minute at their watches. Holmes sat silent and
composed, his eyelids half shut, but every sense on the alert.
He raised his head with a sudden jerk.

"He is coming," said he.

There had been a furtive step past the door. Now it returned.
We heard a shuffling sound outside, and then two sharp taps with
the knocker. Holmes rose, motioning us to remain seated. The gas
in the hall was a mere point of light. He opened the outer door,
and then as a dark figure slipped past him he closed and fastened
it. "This way!" we heard him say, and a moment later our man
stood before us. Holmes had followed him closely, and as the man
turned with a cry of surprise and alarm he caught him by the
collar and threw him back into the room. Before our prisoner had
recovered his balance the door was shut and Holmes standing with
his back against it. The man glared round him, staggered, and
fell senseless upon the floor. With the shock, his broad-brimmed
hat flew from his head, his cravat slipped sown from his lips,
and there were the long light beard and the soft, handsome
delicate features of Colonel Valentine Walter.

Holmes gave a whistle of surprise.

"You can write me down an ass this time, Watson," said he. "This
was not the bird that I was looking for."

"Who is he?" asked Mycroft eagerly.

"The younger brother of the late Sir James Walter, the head of
the Submarine Department. Yes, yes; I see the fall of the cards.
He is coming to. I think that you had best leave his examination
to me."

We had carried the prostrate body to the sofa. Now our prisoner
sat up, looked round him with a horror-stricken face, and passed
his hand over his forehead, like one who cannot believe his own

"What is this?" he asked. "I came here to visit Mr. Oberstein."

"Everything is known, Colonel Walter," said Holmes. "How an
English gentleman could behave in such a manner is beyond my
comprehension. But your whole correspondence and relations with
Oberstein are within our knowledge. So also are the
circumstances connected with the death of young Cadogan West.
Let me advise you to gain at least the small credit for
repentance and confession, since there are still some details
which we can only learn from your lips."

The man groaned and sank his face in his hands. We waited, but
he was silent.

"I can assure you," said Holmes, "that every essential is already
known. We know that you were pressed for money; that you took an
impress of the keys which your brother held; and that you entered
into a correspondence with Oberstein, who answered your letters
through the advertisement columns of the Daily Telegraph. We are
aware that you went down to the office in the fog on Monday
night, but that you were seen and followed by young Cadogan West,
who had probably some previous reason to suspect you. He saw
your theft, but could not give the alarm, as it was just possible
that you were taking the papers to your brother in London.
Leaving all his private concerns, like the good citizen that he
was, he followed you closely in the fog and kept at your heels
until you reached this very house. There he intervened, and then
it was, Colonel Walter, that to treason you added the more
terrible crime of murder."

"I did not! I did not! Before God I swear that I did not!"
cried our wretched prisoner.

"Tell us, then, how Cadogan West met his end before you laid him
upon the roof of a railway carriage."

"I will. I swear to you that I will. I did the rest. I confess
it. It was just as you say. A Stock Exchange debt had to be
paid. I needed the money badly. Oberstein offered me five
thousand. It was to save myself from ruin. But as to murder, I
am as innocent as you."

"What happened, then?"

"He had his suspicions before, and he followed me as you
describe. I never knew it until I was at the very door. It was
thick fog, and one could not see three yards. I had given two
taps and Oberstein had come to the door. The young man rushed up
and demanded to know what we were about to do with the papers.
Oberstein had a short life-preserver. He always carried it with
him. As West forced his way after us into the house Oberstein
struck him on the head. The blow was a fatal one. He was dead
within five minutes. There he lay in the hall, and we were at
our wit's end what to do. Then Oberstein had this idea about the
trains which halted under his back window. But first he examined
the papers which I had brought. He said that three of them were
essential, and that he must keep them. 'You cannot keep them,'
said I. 'There will be a dreadful row at Woolwich if they are
not returned.' 'I must keep them,' said he, 'for they are so
technical that it is impossible in the time to make copies.'
'Then they must all go back together to-night,' said I. He
thought for a little, and then he cried out that he had it.
'Three I will keep,' said he. 'The others we will stuff into the
pocket of this young man. When he is found the whole business
will assuredly be put to his account.' I could see no other way
out of it, so we did as he suggested. We waited half an hour at
the window before a train stopped. It was so thick that nothing
could be seen, and we had no difficulty in lowering West's body
on to the train. That was the end of the matter so far as I was

"And your brother?"

"He said nothing, but he had caught me once with his keys, and I
think that he suspected. I read in his eyes that he suspected.
As you know, he never held up his head again."

There was silence in the room. It was broken by Mycroft Holmes.

"Can you not make reparation? It would ease your conscience, and
possibly your punishment."

"What reparation can I make?"

"Where is Oberstein with the papers?"

"I do not know."

"Did he give you no address?"

"He said that letters to the Hotel du Louvre, Paris, would
eventually reach him."

"Then reparation is still within your power," said Sherlock

"I will do anything I can. I owe this fellow no particular good-
will. He has been my ruin and my downfall."

"Here are paper and pen. Sit at this desk and write to my
dictation. Direct the envelope to the address given. That is
right. Now the letter:

"Dear Sir:

"With regard to our transaction, you will no doubt have observed
by now that one essential detail is missing. I have a tracing
which will make it complete. This has involved me in extra
trouble, however, and I must ask you for a further advance of
five hundred pounds. I will not trust it to the post, nor will I
take anything but gold or notes. I would come to you abroad, but
it would excite remark if I left the country at present.
Therefore I shall expect to meet you in the smoking-room of the
Charing Cross Hotel at noon on Saturday. Remember that only
English notes, or gold, will be taken.

"That will do very well. I shall be very much surprised if it
does not fetch our man."

And it did! It is a matter of history--that secret history of a
nation which is often so much more intimate and interesting than
its public chronicles--that Oberstein, eager to complete the coup
of his lifetime, came to the lure and was safely engulfed for
fifteen years in a British prison. In his trunk were found the
invaluable Bruce-Partington plans, which he had put up for
auction in all the naval centres of Europe.

Colonel Walter died in prison towards the end of the second year
of his sentence. As to Holmes, he returned refreshed to his
monograph upon the Polyphonic Motets of Lassus, which has since
been printed for private circulation, and is said by experts to
be the last word upon the subject. Some weeks afterwards I
learned incidentally that my friend spent a day at Windsor,
whence be returned with a remarkably fine emerald tie-pin. When
I asked him if he had bought it, he answered that it was a
present from a certain gracious lady in whose interests he had
once been fortunate enough to carry out a small commission. He
said no more; but I fancy that I could guess at that lady's
august name, and I have little doubt that the emerald pin will
forever recall to my friend's memory the adventure of the Bruce-
Partington plans.
