“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. Then I thought of the whistle. Of course he must recall the snake before the morning light revealed it to the victim. He had trained it, probably by the use of the milk which we saw, to return to him when summoned. He would put it through this ventilator at the hour that he thought best, with the certainty that it would crawl down the rope and land on the bed. It might or might not bite the occupant, perhaps she might escape every night for a week, but sooner or later she must fall a victim.
“I had come to these conclusions before ever I had entered his room.An inspection of his chair showed me that he had been in the habit of standing on it, which of course would be necessary in order that he should reach the ventilator. The sight of the safe, the saucer of milk, and the loop of whipcord were enough to finally dispel any doubts which may have remained. The metallic clang heard by Miss Stoner was obviously caused by her stepfather hastily closing the door of his safe upon its terrible occupant. Having once made up my mind, you know the steps which I took in order to put the matter to the proof. I heard the creature hiss as I have no doubt that you did also, and I instantly lit the light and attacked it.”
“With the result of driving it through the ventilator.”
“And also with the result of causing it to turn upon its master at the other side. Some of the blows of my cane came home and roused its snakish temper, so that it flew upon the first person it saw. In this way I am no doubt indirectly responsible for Dr. Grimesby Roylott’s death, and I cannot say that it is likely to weigh very heavily upon my conscience.”
IX. THE ADVENTURE OF THE ENGINEER’S THUMB
Of all the problems which have been submitted to my friend,Mr. Sherlock Holmes,for solution during the years of our intimacy,there were only two which I was the means of introducing to his notice—that of Mr. Hatherley’s thumb, and that of Colonel Warburton’s madness. Of these the latter may have afforded a finer field for an acute and original observer, but the other was so strange in its inception and so dramatic in its details that it may be the more worthy of being placed upon record, even if it gave my friend fewer openings for those deductive methods of reasoning by which he achieved such remarkable results. The story has, I believe, been told more than once in the newspapers, but, like all such narratives, its effect is much less striking when set forth _en bloc_ in a single half-column of print than when the facts slowly evolve before your own eyes, and the mystery clears gradually away as each new discovery furnishes a step which leads on to the complete truth. At the time the circumstances made a deep impression upon me, and the lapse of two years has hardly served to weaken the effect.
It was in the summer of ’89, not long after my marriage,that the events occurred which I am now about to summarise.I had returned to civil practice and had finally abandoned Holmes in his Baker Street rooms, although I continually visited him and occasionally even persuaded him to forgo his Bohemian habits so far as to come and visit us. My practice had steadily increased, and as I happened to live at no very great distance from Paddington Station, I got a few patients from among the officials. One of these, whom I had cured of a painful and lingering disease, was never weary of advertising my virtues and of endeavouring to send me on every sufferer over whom he might have any influence.
One morning, at a little before seven o’clock,I was awakened by the maid tapping at the door to announce that two men had come from Paddington and were waiting in the consulting-room. I dressed hurriedly, for I knew by experience that railway cases were seldom trivial, and hastened downstairs. As I descended, my old ally, the guard, came out of the room and closed the door tightly behind him.
“I’ve got him here,” he whispered,jerking his thumb over his shoulder; “he’s all right.”
“What is it, then?” I asked, for his manner suggested that it was some strange creature which he had caged up in my room.
“It’s a new patient,” he whispered.“I thought I’d bring him round myself;then he couldn’t slip away. There he is,all safe and sound. I must go now, Doctor;I have my dooties, just the same as you.” And off he went, this trusty tout,without even giving me time to thank him.
I entered my consulting-room and found a gentleman seated by the table.He was quietly dressed in a suit of heather tweed with a soft cloth cap which he had laid down upon my books. Round one of his hands he had a handkerchief wrapped, which was mottled all over with bloodstains. He was young, not more than five-and-twenty, I should say, with a strong, masculine face; but he was exceedingly pale and gave me the impression of a man who was suffering from some strong agitation, which it took all his strength of mind to control.
“I am sorry to knock you up so early, Doctor,” said he,“but I have had a very serious accident during the night.I came in by train this morning,and on inquiring at Paddington as to where I might find a doctor,a worthy fellow very kindly escorted me here.I gave the maid a card,but I see that she has left it upon the side-table.”
I took it up and glanced at it. “Mr. Victor Hatherley,hydraulic engineer, 16A, Victoria Street (3rd floor).” That was the name, style,and abode of my morning visitor.“I regret that I have kept you waiting,” said I,sitting down in my library-chair.“You are fresh from a night journey, I understand,which is in itself a monotonous occupation.”
“Oh, my night could not be called monotonous,” said he,and laughed. He laughed very heartily, with a high,ringing note, leaning back in his chair and shaking his sides.All my medical instincts rose up against that laugh.
“Stop it!” I cried; “pull yourself together!” and I poured out some water from a caraffe.
It was useless, however.He was off in one of those hysterical outbursts which come upon a strong nature when some great crisis is over and gone. Presently he came to himself once more, very weary and pale-looking.
“I have been making a fool of myself,” he gasped.
“Not at all. Drink this.” I dashed some brandy into the water,and the colour began to come back to his bloodless cheeks.
