continued; fingering the rope; 〃that our wooden…legged friend; though a
fair climber; was not a professional sailor。 His hands were far from
horny。 My lens discloses more than one blood…mark; especially towards
the end of the rope; from which I gather that he slipped down with such
velocity that he took the skin off his hand。〃
〃This is all very well;〃 said I; 〃but the thing becomes more
unintelligible than ever。 How about this mysterious ally? How came he
into the room?〃
〃Yes; the ally!〃 repeated Holmes; pensively。 〃There are features of
interest about this ally。 He lifts the case from the regions of the
commonplace。 I fancy that this ally breaks fresh ground in the annals of
crime in this country;though parallel cases suggest themselves from India;
and; if my memory serves me; from Senegambia。〃
〃How came he; then?〃 I reiterated。 〃The door is locked; the
window is inaccessible。 Was it through the chimney?〃
The grate is much too small;〃 he answered。 〃I had already considered
that possibility。〃
〃How then?〃 I persisted。
〃You will not apply my precept;〃 he said; shaking his head。 〃How
often have I said to you that when you have eliminated the impossible
whatever remains; HOWEVER IMPROBABLE; must be the truth? We
know that he did not come through the door; the window; or the chimney。
We also know that he could not have been concealed in the room; as there
is no concealment possible。 Whence; then; did he come?〃

〃He came through the hole in the roof;〃 I cried。
〃Of course he did。 He must have done so。 If you will have the
kindness to hold the lamp for me; we shall now extend our researches to
the room above;the secret room in which the treasure was found。〃
He mounted the steps; and; seizing a rafter with either hand; he swung
himself up into the garret。 Then; lying on his face; he reached down for
the lamp and held it while I followed him。
The chamber in which we found ourselves was about ten feet one way
and six the other。 The floor was formed by the rafters; with thin lath…and…
plaster between; so that in walking one had to step from beam to beam。
The roof ran up to an apex; and was evidently the inner shell of the true
roof of the house。 There was no furniture of any sort; and the
accumulated dust of years lay thick upon the floor。
〃Here you are; you see;〃 said Sherlock Holmes; putting his hand
against the sloping wall。 〃This is a trap…door which leads out on to the
roof。 I can press it back; and here is the roof itself; sloping at a gentle
angle。 This; then; is the way by which Number One entered。 Let us see
if we can find one other traces of his individuality。〃
He held down the lamp to the floor; and as he did so I saw for the
second time that night a startled; surprised look come over his face。 For
myself; as I followed his gaze my skin was cold under my clothes。 The
floor was covered thickly with the prints of a naked foot;clear; well
defined; perfectly formed; but scarce half the size of those of an ordinary
man。
〃Holmes;〃 I said; in a whisper; 〃a child has done the horrid thing。〃
He had recovered his self…possession in an instant。 〃I was staggered
for the moment;〃 he said; 〃but the thing is quite natural。 My memory
failed me; or I should have been able to foretell it。 There is nothing more
to be learned here。 Let us go down。〃
〃What is your theory; then; as to those footmarks?〃 I asked; eagerly;
when we had regained the lower room once more。
〃My dear Watson; try a little analysis yourself;〃 said he; with a touch
of impatience。 〃You know my methods。 Apply them; and it will be
instructive to compare results。〃

〃I cannot conceive anything which will cover the facts;〃 I answered。
〃It will be clear enough to you soon;〃 he said; in an off…hand way。 〃I
think that there is nothing else of importance here; but I will look。〃 He
whipped out his lens and a tape measure; and hurried about the room on
his knees; measuring; comparing; examining; with his long thin nose only
a few inches from the planks; and his beady eyes gleaming and deep…set
like those of a bird。 So swift; silent; and furtive were his movements;
like those of a trained blood…hound picking out a scent; that I could not but
think what a terrible criminal he would have made had he turned his
energy and sagacity against the law; instead of exerting them in its defense。
As he hunted about; he kept muttering to himself; and finally he broke out
into a loud crow of delight。
〃We are certainly in luck;〃 said he。 〃We ought to have very little
trouble now。 Number One has had the misfortune to tread in the creosote。
You can see the outline of the edge of his small foot here at the side of this
evil…smelling mess。 The carboy has been cracked; You see; and the stuff
has leaked out。〃
〃What then?〃 I asked。
〃Why; we have got him; that's all;〃 said he。 〃I know a dog that would
follow that scent to the world's end。 If a pack can track a trailed herring
across a shire; how far can a specially…trained hound follow so pungent a
smell as this? It sounds like a sum in the rule of three。 The answer
should give us theBut halloo! here are the accredited representatives of
the law。〃
Heavy steps and the clamor of loud voices were audible from below;
and the hall door shut with a loud crash。
〃Before they come;〃 said Holmes; 〃just put your hand here on this
poor fellow's arm; and here on his leg。 What do you feel?〃
〃The muscles are as hard as a board;〃 I answered。
〃Quite so。 They are in a state of extreme contraction; far exceeding
the usual rigor mortis。 Coupled with this distortion of the face; this
Hippocratic smile; or 'risus sardonicus;' as the old writers called it; what
conclusion would it suggest to your mind?〃
〃Death from some powerful vegetable alkaloid;〃 I answered;〃some

strychnine…like substance which would produce tetanus。〃
〃That was the idea which occurred to me the instant I saw the drawn
muscles of the face。 On getting into the room I at once looked for the
means by which the poison had entered the system。 As you saw; I
discovered a thorn which had been driven or shot with no great force into
the scalp。 You observe that the part struck was that which would be
turned towards the hole in the ceiling if the man were erect in his chair。
Now examine the thorn。〃
I took it up gingerly and held it in the light of the lantern。 It was long;
sharp; and black; with a glazed look near the point as though some gummy
substance had dried upon it。 The bl
