"I have one or two things which I would wish to do now that I am
in town. But I shall return by the twelve o'clock train, so as to
be there in time for your coming. "

"And you may expect us early in the afternoon. I have myself some
small business matters to attend to. Will you not wait and
breakfast? "

"No, I must go. My heart is lightened already since I have
confided my trouble to you. I shall look forward to seeing you
again this afternoon. " She dropped her thick black veil over her
face and glided from the room.

"And what do you think of it all, Watson? " asked Sherlock Holmes,
leaning back in his chair.

"It seems to me to be a most dark and sinister business. "

"Dark enough and sinister enough. "

"Yet if the lady is correct in saying that the flooring and walls
are sound, and that the door, window, and chimney are impassable,
then her sister must have been undoubtedly alone when she met her
mysterious end. "

"What becomes, then, of these nocturnal whistles, and what of the
very peculiar words of the dying woman? "

"I cannot think. "

"When you combine the ideas of whistles at night, the presence of
a band of gipsies who are on intimate terms with this old doctor,
the fact that we have every reason to believe that the doctor has
an interest in preventing his stepdaughter's marriage, the dying
allusion to a band, and, finally, the fact that Miss Helen Stoner
heard a metallic clang, which might have been caused by one of
those metal bars that secured the shutters falling back into its
place, I think that there is good ground to think that the
mystery may be cleared along those lines. "

"But what, then, did the gipsies do? "

"I cannot imagine. "

"I see many objections to any such theory. "

"And so do I. It is precisely for that reason that we are going
to Stoke Moran this day. I want to see whether the objections are
fatal, or if they may be explained away. But what in the name of
the devil! "

The ejaculation had been drawn from my companion by the fact that
our door had been suddenly dashed open, and that a huge man had
framed himself in the aperture. His costume was a peculiar
mixture of the professional and of the agricultural, having a
black top-hat, a long frock-coat, and a pair of high gaiters,
with a hunting-crop swinging in his hand. So tall was he that his
hat actually brushed the cross bar of the doorway, and his
breadth seemed to span it across from side to side. A large face,
seared with a thousand wrinkles, burned yellow with the sun, and
marked with every evil passion, was turned from one to the other
of us, while his deep-set, bile-shot eyes, and his high, thin,
fleshless nose, gave him somewhat the resemblance to a fierce old
bird of prey.

"Which of you is Holmes? " asked this apparition.

"My name, sir; but you have the advantage of me," said my
companion quietly.

"I am Dr. Grimesby Roylott, of Stoke Moran. "

"Indeed, Doctor," said Holmes blandly. "Pray take a seat. "

"I will do nothing of the kind. My stepdaughter has been here. I
have traced her. What has she been saying to you? "

"It is a little cold for the time of the year," said Holmes.

"What has she been saying to you? " screamed the old man
furiously.

"But I have heard that the crocuses promise well," continued my
companion imperturbably.

"Ha! You put me off, do you? " said our new visitor, taking a step
forward and shaking his hunting-crop. "I know you, you scoundrel!
I have heard of you before. You are Holmes, the meddler. "

My friend smiled.

"Holmes, the busybody! "

His smile broadened.

"Holmes, the Scotland Yard Jack-in-office! "

Holmes chuckled heartily. "Your conversation is most
entertaining," said he. "When you go out close the door, for
there is a decided draught. "

"I will go when I have said my say. Don't you dare to meddle with
my affairs. I know that Miss Stoner has been here. I traced her!
I am a dangerous man to fall foul of! See here. " He stepped
swiftly forward, seized the poker, and bent it into a curve with
his huge brown hands.

"See that you keep yourself out of my grip," he snarled, and
hurling the twisted poker into the fireplace he strode out of the
room.

"He seems a very amiable person," said Holmes, laughing. "I am
not quite so bulky, but if he had remained I might have shown him
that my grip was not much more feeble than his own. " As he spoke
he picked up the steel poker and, with a sudden effort,
straightened it out again.

"Fancy his having the insolence to confound me with the official
detective force! This incident gives zest to our investigation,
however, and I only trust that our little friend will not suffer
from her imprudence in allowing this brute to trace her. And now,
Watson, we shall order breakfast, and afterwards I shall walk
down to Doctors' Commons, where I hope to get some data which may
help us in this matter. "


It was nearly one o'clock when Sherlock Holmes returned from his
excursion. He held in his hand a sheet of blue paper, scrawled
over with notes and figures.

"I have seen the will of the deceased wife," said he. "To
determine its exact meaning I have been obliged to work out the
present prices of the investments with which it is concerned. The
total income, which at the time of the wife's death was little
short of 1100 pounds, is now, through the fall in agricultural
prices, not more than 750 pounds. Each daughter can claim an
income of 250 pounds, in case of marriage. It is evident,
therefore, that if both girls had married, this beauty would have
had a mere pittance, while even one of them would cripple him to
a very serious extent. My morning's work has not been wasted,
since it has proved that he has the very strongest motives for
standing in the way of anything of the sort. And now, Watson,
this is too serious for dawdling, especially as the old man is
aware that we are interesting ourselves in his affairs; so if you
are ready, we shall call a cab and drive to Waterloo. I should be
very much obliged if you would slip your revolver into your
pocket. An Eley's No. 2 is an excellent argument with gentlemen
who can twist steel pokers into knots. That and a tooth-brush
are, I think, all that we need. "

At Waterloo we were fortunate in catching a train for
Leatherhead, where we hired a trap at the station inn and drove
for four or five miles through the lovely Surrey lanes. It was a
perfect day, with a bright sun and a few fleecy clouds in the
heavens. The trees and wayside hedges were just throwing out
their first green shoots, and the air was full of the pleasant
smell of the moist earth. To me at least there was a strange
contrast between the sweet promise of the spring and this
sinister quest upon which we were engaged. My companion sat in
the front of the trap, his arms folded, his hat pulled down over
his eyes, and his chin sunk upon his breast, buried in the
deepest thought. Suddenly, however, he started, tapped me on the
shoulder, and pointed over the meadows.

"Look there! " said he.

A heavily timbered park stretched up in a gentle slope,
thickening into a grove at the highest point. From amid the
branches there jutted out the grey gables and high roof-tree of a
very old mansion.

"Stoke Moran? " said he.

"Yes, sir, that be the house of Dr. Grimesby Roylott," remarked
the driver.

"There is some building going on there," said Holmes; "that is
where we are going. "

"There's the village," said the driver, pointing to a cluster of
roofs some distance to the left; "but if you want to get to the
house, you'll find it shorter to get over this stile, and so by
the foot-path over the fields. There it is, where the lady is
walking. "

"And the lady, I fancy, is Miss Stoner," observed Holmes, shading
his eyes. "Yes, I think we had better do as you suggest. "

We got off, paid our fare, and the trap rattled back on its way
to Leatherhead.

"I thought it as well," said Holmes as we climbed the stile,
"that this fellow should think we had come here as architects, or
on some definite business. It may stop his gossip.
Good-afternoon, Miss Stoner. You see that we have been as good as
our word. "

Our client of the morning had hurried forward to meet us with a
face which spoke her joy. "I have been waiting so eagerly for
you," she cried, shaking hands with us warmly. "All has turned
out splendidly. Dr. Roylott has gone to town, and it is unlikely
that he will be back before evening. "

"We have had the pleasure of making the doctor's acquaintance,"
said Holmes, and in a few words he sketched out what had
occurred. Miss Stoner turned white to the lips as she listened.

"Good heavens! " she cried, "he has followed me, then. "

"So it appears. "

"He is so cunning that I never know when I am safe from him. What
will he say when he returns? "

"He must guard himself, for he may find that there is someone
more cunning than himself upon his track. You must lock yourself
up from him to-night. If he is violent, we shall take you away to
your aunt's at Harrow. Now, we must make the best use of our
time, so kindly take us at once to the rooms which we are to
examine. "

The building was of grey, lichen-blotched stone, with a high
central portion and two curving wings, like the claws of a crab,
thrown out on each side. In one of these wings the windows were
broken and blocked with wooden boards, while the roof was partly
caved in, a picture of ruin. The central portion was in little
better repair, but the right-hand block was comparatively modern,
and the blinds in the windows, with the blue smoke curling up
from the chimneys, showed that this was where the family resided.
Some scaffolding had been erected against the end wall, and the
stone-work had been broken into, but there were no signs of any
workmen at the moment of our visit. Holmes walked slowly up and
down the ill-trimmed lawn and examined with deep attention the
outsides of the windows.

"This, I take it, belongs to the room in which you used to sleep,
the centre one to your sister's, and the one next to the main
building to Dr. Roylott's chamber? "

"Exactly so. But I am now sleeping in the middle one. "

"Pending the alterations, as I understand. By the way, there does
not seem to be any very pressing need for repairs at that end
wall. "

"There were none. I believe that it was an excuse to move me from
my room. "

"Ah! that is suggestive. Now, on the other side of this narrow
wing runs the corridor from which these three rooms open. There
are windows in it, of course? "

"Yes, but very small ones. Too narrow for anyone to pass
through. "

"As you both locked your doors at night, your rooms were
unapproachable from that side. Now, would you have the kindness
to go into your room and bar your shutters? "

Miss Stoner did so, and Holmes, after a careful examination
through the open window, endeavoured in every way to force the
shutter open, but without success. There was no slit through
which a knife could be passed to raise the bar. Then with his
lens he tested the hinges, but they were of solid iron, built
firmly into the massive masonry. "Hum! " said he, scratching his
chin in some perplexity, "my theory certainly presents some
difficulties. No one could pass these shutters if they were
bolted. Well, we shall see if the inside throws any light upon
the matter. "

A small side door led into the whitewashed corridor from which
the three bedrooms opened. Holmes refused to examine the third
chamber, so we passed at once to the second, that in which Miss
Stoner was now sleeping, and in which her sister had met with her
fate. It was a homely little room, with a low ceiling and a
gaping fireplace, after the fashion of old country-houses. A
brown chest of drawers stood in one corner, a narrow
white-counterpaned bed in another, and a dressing-table on the
left-hand side of the window. These articles, with two small
wicker-work chairs, made up all the furniture in the room save
for a square of Wilton carpet in the centre. The boards round and
the panelling of the walls were of brown, worm-eaten oak, so old
and discoloured that it may have dated from the original building
of the house. Holmes drew one of the chairs into a corner and sat
silent, while his eyes travelled round and round and up and down,
taking in every detail of the apartment.

"Where does that bell communicate with? " he asked at last
pointing to a thick bell-rope which hung down beside the bed, the
tassel actually lying upon the pillow.

"It goes to the housekeeper's room. "

"It looks newer than the other things? "

"Yes, it was only put there a couple of years ago. "

"Your sister asked for it, I suppose? "

"No, I never heard of her using it. We used always to get what we
wanted for ourselves. "

"Indeed, it seemed unnecessary to put so nice a bell-pull there.
You will excuse me for a few minutes while I satisfy myself as to
this floor. " He threw himself down upon his face with his lens in
his hand and crawled swiftly backward and forward, examining
minutely the cracks between the boards. Then he did the same with
the wood-work with which the chamber was panelled. Finally he
walked over to the bed and spent some time in staring at it and
in running his eye up and down the wall. Finally he took the
bell-rope in his hand and gave it a brisk tug.

"Why, it's a dummy," said he.

"Won't it ring? "

"No, it is not even attached to a wire. This is very interesting.
You can see now that it is fastened to a hook just above where
the little opening for the ventilator is. "

"How very absurd! I never noticed that before. "

"Very strange! " muttered Holmes, pulling at the rope. "There are
one or two very singular points about this room. For example,
what a fool a builder must be to open a ventilator into another
room, when, with the same trouble, he might have communicated
with the outside air! "

"That is also quite modern," said the lady.

"Done about the same time as the bell-rope? " remarked Holmes.

"Yes, there were several little changes carried out about that
time. "

"They seem to have been of a most interesting character--dummy
bell-ropes, and ventilators which do not ventilate. With your
permission, Miss Stoner, we shall now carry our researches into
the inner apartment. "

Dr. Grimesby Roylott's chamber was larger than that of his
step-daughter, but was as plainly furnished. A camp-bed, a small
wooden shelf full of books, mostly of a technical character, an
armchair beside the bed, a plain wooden chair against the wall, a
round table, and a large iron safe were the principal things
which met the eye. Holmes walked slowly round and examined each
and all of them with the keenest interest.

"What's in here? " he asked, tapping the safe.

"My stepfather's business papers. "

"Oh! you have seen inside, then? "

"Only once, some years ago. I remember that it was full of
papers.
"

"There isn't a cat in it, for example? "

"No. What a strange idea! "

"Well, look at this! " He took up a small saucer of milk which
stood on the top of it.

"No; we don't keep a cat. But there is a cheetah and a baboon. "

"Ah, yes, of course! Well, a cheetah is just a big cat, and yet a
saucer of milk does not go very far in satisfying its wants, I
daresay. There is one point which I should wish to determine. " He
squatted down in front of the wooden chair and examined the seat
of it with the greatest attention.

"Thank you. That is quite settled," said he, rising and putting
his lens in his pocket. "Hullo! Here is something interesting! "

The object which had caught his eye was a small dog lash hung on
one corner of the bed. The lash, however, was curled upon itself
and tied so as to make a loop of whipcord.

"What do you make of that, Watson? "

"It's a common enough lash. But I don't know why it should be
tied. "

"That is not quite so common, is it? Ah, me! it's a wicked world,
and when a clever man turns his brains to crime it is the worst
of all. I think that I have seen enough now, Miss Stoner, and
with your permission we shall walk out upon the lawn. "

I had never seen my friend's face so grim or his brow so dark as
it was when we turned from the scene of this investigation. We
had walked several times up and down the lawn, neither Miss
Stoner nor myself liking to break in upon his thoughts before he
roused himself from his reverie.

"It is very essential, Miss Stoner," said he, "that you should
absolutely follow my advice in every respect. "

"I shall most certainly do so. "

"The matter is too serious for any hesitation. Your life may
depend upon your compliance. "

"I assure you that I am in your hands. "

"In the first place, both my friend and I must spend the night in
your room. "

Both Miss Stoner and I gazed at him in astonishment.

"Yes, it must be so. Let me explain. I believe that that is the
village inn over there? "

"Yes, that is the Crown. "

"Very good. Your windows would be visible from there? "

"Certainly. "

"You must confine yourself to your room, on pretence of a
headache, when your stepfather comes back. Then when you hear him
retire for the night, you must open the shutters of your window,
undo the hasp, put your lamp there as a signal to us, and then
withdraw quietly with everything which you are likely to want
into the room which you used to occupy. I have no doubt that, in
spite of the repairs, you could manage there for one night. "

"Oh, yes, easily. "

"The rest you will leave in our hands. "

"But what will you do? "

"We shall spend the night in your room, and we shall investigate
the cause of this noise which has disturbed you. "

"I believe, Mr. Holmes, that you have already made up your mind,"
said Miss Stoner, laying her hand upon my companion's sleeve.

"Perhaps I have. "

"Then, for pity's sake, tell me what was the cause of my sister's
death. "

"I should prefer to have clearer proofs before I speak. "

"You can at least tell me whether my own thought is correct, and
if she died from some sudden fright. "

"No, I do not think so. I think that there was probably some more
tangible cause. And now, Miss Stoner, we must leave you for if
Dr. Roylott returned and saw us our journey would be in vain.
Good-bye, and be brave, for if you will do what I have told you,
you may rest assured that we shall soon drive away the dangers
that threaten you. "

Sherlock Holmes and I had no difficulty in engaging a bedroom and
sitting-room at the Crown Inn. They were on the upper floor, and
from our window we could command a view of the avenue gate, and
of the inhabited wing of Stoke Moran Manor House. At dusk we saw
Dr. Grimesby Roylott drive past, his huge form looming up beside
the little figure of the lad who drove him. The boy had some
slight difficulty in undoing the heavy iron gates, and we heard
the hoarse roar of the doctor's voice and saw the fury with which
he shook his clinched fists at him. The trap drove on, and a few
minutes later we saw a sudden light spring up among the trees as
the lamp was lit in one of the sitting-rooms.

"Do you know, Watson," said Holmes as we sat together in the
gathering darkness, "I have really some scruples as to taking you
to-night. There is a distinct element of danger. "

"Can I be of assistance? "

"Your presence might be invaluable. "

"Then I shall certainly come. "

"It is very kind of you. "

"You speak of danger. You have evidently seen more in these rooms
than was visible to me. "

"No, but I fancy that I may have deduced a little more. I imagine
that you saw all that I did. "

"I saw nothing remarkable save the bell-rope, and what purpose
that could answer I confess is more than I can imagine. "

"You saw the ventilator, too? "

"Yes, but I do not think that it is such a very unusual thing to
have a small opening between two rooms. It was so small that a
rat could hardly pass through. "

"I knew that we should find a ventilator before ever we came to
Stoke Moran. "

"My dear Holmes! "

"Oh, yes, I did. You remember in her statement she said that her
sister could smell Dr. Roylott's cigar. Now, of course that
suggested at once that there must be a communication between the
two rooms. It could only be a small one, or it would have been
remarked upon at the coroner's inquiry. I deduced a ventilator. "

"But what harm can there be in that? "

"Well, there is at least a curious coincidence of dates. A
ventilator is made, a cord is hung, and a lady who sleeps in the
bed dies. Does not that strike you? "

"I cannot as yet see any connection. "

"Did you observe anything very peculiar about that bed? "

"No. "

"It was clamped to the floor. Did you ever see a bed fastened
like that before? "

"I cannot say that I have. "

"The lady could not move her bed. It must always be in the same
relative position to the ventilator and to the rope--or so we may
call it, since it was clearly never meant for a bell-pull. "

"Holmes," I cried, "I seem to see dimly what you are hinting at.
We are only just in time to prevent some subtle and horrible
crime. "

"Subtle enough and horrible enough. When a doctor does go wrong
he is the first of criminals. He has nerve and he has knowledge.
Palmer and Pritchard were among the heads of their profession.
This man strikes even deeper, but I think, Watson, that we shall
be able to strike deeper still. But we shall have horrors enough
before the night is over; for goodness' sake let us have a quiet
pipe and turn our minds for a few hours to something more
cheerful. "


About nine o'clock the light among the trees was extinguished,
and all was dark in the direction of the Manor House. Two hours
passed slowly away, and then, suddenly, just at the stroke of
eleven, a single bright light shone out right in front of us.

"That is our signal," said Holmes, springing to his feet; "it
comes from the middle window. "

As we passed out he exchanged a few words with the landlord,
explaining that we were going on a late visit to an acquaintance,
and that it was possible that we might spend the night there. A
moment later we were out on the dark road, a chill wind blowing
in our faces, and one yellow light twinkling in front of us
through the gloom to guide us on our sombre errand.

There was little difficulty in entering the grounds, for
unrepaired breaches gaped in the old park wall. Making our way
among the trees, we reached the lawn, crossed it, and were about
to enter through the window when out from a clump of laurel
bushes there darted what seemed to be a hideous and distorted
child, who threw itself upon the grass with writhing limbs and
then ran swiftly across the lawn into the darkness.

"My God! " I whispered; "did you see it? "

Holmes was for the moment as startled as I. His hand closed like
a vice upon my wrist in his agitation. Then he broke into a low
laugh and put his lips to my ear.

"It is a nice household," he murmured. "That is the baboon. "

I had forgotten the strange pets which the doctor affected. There
was a cheetah, too; perhaps we might find it upon our shoulders
at any moment. I confess that I felt easier in my mind when,
after following Holmes' example and slipping off my shoes, I
found myself inside the bedroom. My companion noiselessly closed
the shutters, moved the lamp onto the table, and cast his eyes
round the room. All was as we had seen it in the daytime. Then
creeping up to me and making a trumpet of his hand, he whispered
into my ear again so gently that it was all that I could do to
distinguish the words:

"The least sound would be fatal to our plans. "

I nodded to show that I had heard.

"We must sit without light. He would see it through the
ventilator. "

I nodded again.

"Do not go asleep; your very life may depend upon it. Have your
pistol ready in case we should need it. I will sit on the side of
the bed, and you in that chair. "

I took out my revolver and laid it on the corner of the table.

Holmes had brought up a long thin cane, and this he placed upon
the bed beside him. By it he laid the box of matches and the
stump of a candle. Then he turned down the lamp, and we were left
in darkness.

How shall I ever forget that dreadful vigil? I could not hear a
sound, not even the drawing of a breath, and yet I knew that my
companion sat open-eyed, within a few feet of me, in the same
state of nervous tension in which I was myself. The shutters cut
off the least ray of light, and we waited in absolute darkness.

From outside came the occasional cry of a night-bird, and once at
our very window a long drawn catlike whine, which told us that
the cheetah was indeed at liberty. Far away we could hear the
deep tones of the parish clock, which boomed out every quarter of
an hour. How long they seemed, those quarters! Twelve struck, and
one and two and three, and still we sat waiting silently for
whatever might befall.

Suddenly there was the momentary gleam of a light up in the
direction of the ventilator, which vanished immediately, but was
succeeded by a strong smell of burning oil and heated metal.
Someone in the next room had lit a dark-lantern. I heard a gentle
sound of movement, and then all was silent once more, though the
smell grew stronger. For half an hour I sat with straining ears.
Then suddenly another sound became audible--a very gentle,
soothing sound, like that of a small jet of steam escaping
continually from a kettle. The instant that we heard it, Holmes
sprang from the bed, struck a match, and lashed furiously with
his cane at the bell-pull.

"You see it, Watson? " he yelled. "You see it? "

But I saw nothing. At the moment when Holmes struck the light I
heard a low, clear whistle, but the sudden glare flashing into my
weary eyes made it impossible for me to tell what it was at which
my friend lashed so savagely. I could, however, see that his face
was deadly pale and filled with horror and loathing. He had
ceased to strike and was gazing up at the ventilator when
suddenly there broke from the silence of the night the most
horrible cry to which I have ever listened. It swelled up louder
and louder, a hoarse yell of pain and fear and anger all mingled
in the one dreadful shriek. They say that away down in the
village, and even in the distant parsonage, that cry raised the
sleepers from their beds. It struck cold to our hearts, and I
stood gazing at Holmes, and he at me, until the last echoes of it
had died away into the silence from which it rose.

"What can it mean? " I gasped.

"It means that it is all over," Holmes answered. "And perhaps,
after all, it is for the best. Take your pistol, and we will
enter Dr. Roylott's room. "

With a grave face he lit the lamp and led the way down the
corridor. Twice he struck at the chamber door without any reply
from within. Then he turned the handle and entered, I at his
heels, with the cocked pistol in my hand.

It was a singular sight which met our eyes. On the table stood a
dark-lantern with the shutter half open, throwing a brilliant
beam of light upon the iron safe, the door of which was ajar.
Beside this table, on the wooden chair, sat Dr. Grimesby Roylott
clad in a long grey dressing-gown, his bare ankles protruding
beneath, and his feet thrust into red heelless Turkish slippers.
Across his lap lay the short stock with the long lash which we
had noticed during the day. His chin was cocked upward and his
eyes were fixed in a dreadful, rigid stare at the corner of the
ceiling. Round his brow he had a peculiar yellow band, with
brownish speckles, which seemed to be bound tightly round his
head. As we entered he made neither sound nor motion.

"The band! the speckled band! " whispered Holmes.

I took a step forward. In an instant his strange headgear began
to move, and there reared itself from among his hair the squat
diamond-shaped head and puffed neck of a loathsome serpent.

"It is a swamp adder! " cried Holmes; "the deadliest snake in
India. He has died within ten seconds of being bitten. Violence
does, in truth, recoil upon the violent, and the schemer falls
into the pit which he digs for another. Let us thrust this
creature back into its den, and we can then remove Miss Stoner to
some place of shelter and let the county police know what has
happened. "

As he spoke he drew the dog-whip swiftly from the dead man's lap,
and throwing the noose round the reptile's neck he drew it from
its horrid perch and, carrying it at arm's length, threw it into
the iron safe, which he closed upon it.

Such are the true facts of the death of Dr. Grimesby Roylott, of
Stoke Moran. It is not necessary that I should prolong a
narrative which has already run to too great a length by telling
how we broke the sad news to the terrified girl, how we conveyed
her by the morning train to the care of her good aunt at Harrow,
of how the slow process of official inquiry came to the
conclusion that the doctor met his fate while indiscreetly
playing with a dangerous pet. The little which I had yet to learn
of the case was told me by Sherlock Holmes as we travelled back
next day.

"I had," said he, "come to an entirely erroneous conclusion which
shows, my dear Watson, how dangerous it always is to reason from
insufficient data. The presence of the gipsies, and the use of
the word 'band,' which was used by the poor girl, no doubt, to
explain the appearance which she had caught a hurried glimpse of
by the light of her match, were sufficient to put me upon an
entirely wrong scent. I can only claim the merit that I instantly
reconsidered my position when, however, it became clear to me
that whatever danger threatened an occupant of the room could not
come either from the window or the door. My attention was
speedily drawn, as I have already remarked to you, to this
ventilator, and to the bell-rope which hung down to the bed. The
discovery that this was a dummy, and that the bed was clamped to
the floor, instantly gave rise to the suspicion that the rope was
there as a bridge for something passing through the hole and
coming to the bed. The idea of a snake instantly occurred to me,
and when I coupled it with my knowledge that the doctor was
furnished with a supply of creatures from India, I felt that I
was probably on the right track. The idea of using a form of
poison which could not possibly be discovered by any chemical
test was just such a one as would occur to a clever and ruthless
man who had had an Eastern training. The rapidity with which such
a poison would take effect would also, from his point of view, be
an advantage. It would be a sharp-eyed coroner, indeed, who could
distinguish the two little dark punctures which would show where
the poison fangs had done their work.
