"It looks like a pawn—one of the Staunton pattern," I said.
"Just what I thought; but it isn't. I've got to make twenty-four of them, and what the Doctor is going to do with them fairly beats me."
"Perhaps he has invented some new game," I suggested facetiously.
"He is always inventing new games and playing them mostly in courts of law, and then the other players generally lose. But this is a puzzler, and no mistake. Twenty-four of these to be turned up in the best-seasoned boxwood! What can they be for? Something to do with the experiments he is carrying on upstairs at this very moment, I expect." He shook his head, and, having carefully returned the drawing to his pocket-book, said, in a solemn tone—"Sir, there are times when the Doctor makes me fairly dance with curiosity. And this is one of them."
Although not afflicted with a curiosity so acute as that of Polton, I found myself speculating at intervals on the nature of my colleague's experiments and the purpose of the singular little objects which he had ordered to be made; but I was unacquainted with any of the cases on which he was engaged, excepting that of Reuben Hornby, and with the latter I was quite unable to connect a set of twenty-four boxwood chessmen. Moreover, on this day, I was to accompany Juliet on her second visit to Holloway, and that circumstance gave me abundant mental occupation of another kind.
At lunch, Thorndyke was animated and talkative but not communicative. He "had some work in the laboratory that he must do himself," he said, but gave no hint as to its nature; and as soon as our meal was finished, he returned to his labours, leaving me to pace up and down the walk, listening with ridiculous eagerness for the sound of the hansom that was to transport me to the regions of the blest, and—incidentally—to Holloway Prison.
When I returned to the Temple, the sitting-room was empty and hideously neat, as the result of Polton's spring-cleaning efforts. My colleague was evidently still at work in the laboratory, and, from the circumstance that the tea-things were set out on the table and a kettle of water placed in readiness on the gas-ring by the fireplace, I gathered that Polton also was full of business and anxious not to be disturbed.
Accordingly, I lit the gas and made my tea, enlivening my solitude by turning over in my mind the events of the afternoon.
Juliet had been charming—as she always was—frank, friendly and unaffectedly pleased to have my companionship. She evidently liked me and did not disguise the fact—why should she indeed?—but treated me with a freedom, almost affectionate, as though I had been a favourite brother; which was very delightful, and would have been more so if I could have accepted the relationship. As to her feelings towards me, I had not the slightest misgiving, and so my conscience was clear; for Juliet was as innocent as a child, with the innocence that belongs to the direct, straightforward nature that neither does evil itself nor looks for evil motives in others. For myself, I was past praying for. The thing was done and I must pay the price hereafter, content to reflect that I had trespassed against no one but myself. It was a miserable affair, and many a heartache did it promise me in the lonely days that were to come, when I should have said "good-bye" to the Temple and gone back to my old nomadic life; and yet I would not have had it changed if I could; would not have bartered the bitter-sweet memories for dull forgetfulness.
But other matters had transpired in the course of our drive than those that loomed so large to me in the egotism of my love. We had spoken of Mr. Hornby and his affairs, and from our talk there had emerged certain facts of no little moment to the inquiry on which I was engaged.
"Misfortunes are proverbially sociable," Juliet had remarked, in reference to her adopted uncle. "As if this trouble about Reuben were not enough, there are worries in the city. Perhaps you have heard of them."
I replied that Walter had mentioned the matter to me.
"Yes," said Juliet rather viciously; "I am not quite clear as to what part that good gentleman has played in the matter. It has come out, quite accidentally, that he had a large holding in the mines himself, but he seems to have 'cut his loss,' as the phrase goes, and got out of them; though how he managed to pay such large differences is more than we can understand. We think he must have raised money somehow to do it."
"Do you know when the mines began to depreciate?" I asked.
"Yes, it was quite a sudden affair—what Walter calls 'a slump'—and it occurred only a few days before the robbery. Mr. Hornby was telling me about it only yesterday, and he recalled it to me by a ridiculous accident that happened on that day."
"What was that?" I inquired.
"Why, I cut my finger and nearly fainted," she answered, with a shamefaced little laugh. "It was rather a bad cut, you know, but I didn't notice it until I found my hand covered with blood. Then I turned suddenly faint, and had to lie down on the hearthrug—it was in Mr. Hornby's study, which I was tidying up at the time. Here I was found by Reuben, and a dreadful fright it gave him at first; and then he tore up his handkerchief to tie up the wounded finger, and you never saw such an awful mess as he got his hands in. He might have been arrested as a murderer, poor boy, from the condition he was in. It will make your professional gorge rise to learn that he fastened up the extemporised bandage with red tape, which he got from the writing table after rooting about among the sacred papers in the most ruthless fashion.
"When he had gone I tried to put the things on the table straight again, and really you might have thought some horrible crime had been committed; the envelopes and papers were all smeared with blood and marked with the print of gory fingers. I remembered it afterwards, when Reuben's thumb-mark was identified, and thought that perhaps one of the papers might have got into the safe by accident; but Mr. Hornby told me that was impossible; he tore the leaf off his memorandum block at the time when he put away the diamonds."
Such was the gist of our conversation as the cab rattled through the streets on the way to the prison; and certainly it contained matter sufficiently important to draw away my thoughts from other subjects, more agreeable, but less relevant to the case. With a sudden remembrance of my duty, I drew forth my notebook, and was in the act of committing the statements to writing, when Thorndyke entered the room.
"Don't let me interrupt you, Jervis," said he. "I will make myself a cup of tea while you finish your writing, and then you shall exhibit the day's catch and hang your nets out to dry."
I was not long in finishing my notes, for I was in a fever of impatience to hear Thorndyke's comments on my latest addition to our store of information. By the time the kettle was boiling my entries were completed, and I proceeded forthwith to retail to my colleague those extracts from my conversation with Juliet that I have just recorded.
He listened, as usual, with deep and critical attention.
"This is very interesting and important," he said, when I had finished; "really, Jervis, you are a most invaluable coadjutor. It seems that information, which would be strictly withheld from the forbidding Jorkins, trickles freely and unasked into the ear of the genial Spenlow. Now, I suppose you regard your hypothesis as having received very substantial confirmation?"
"Certainly, I do."
"And very justifiably. You see now how completely you were in the right when you allowed yourself to entertain this theory of the crime in spite of its apparent improbability. By the light of these new facts it has become quite a probable explanation of the whole affair, and if it could only be shown that Mr. Hornby's memorandum block was among the papers on the table, it would rise to a high degree of probability. The obvious moral is, never disregard the improbable. By the way, it is odd that Reuben failed to recall this occurrence when I questioned him. Of course, the bloody finger-marks were not discovered until he had gone, but one would have expected him to recall the circumstance when I asked him, pointedly, if he had never left bloody finger-prints on any papers."
"I must try to find out if Mr. Hornby's memorandum block was on the table and among the marked papers," I said.
"Yes, that would be wise,"
he answered, "though I don't suppose the information will be forthcoming."
My colleague's manner rather disappointed me. He had heard my report with the greatest attention, he had discussed it with animation, but yet he seemed to attach to the new and—as they appeared to me—highly important facts an interest that was academic rather than practical. Of course, his calmness might be assumed; but this did not seem likely, for John Thorndyke was far too sincere and dignified a character to cultivate in private life the artifices of the actor. To strangers, indeed, he presented habitually a calm and impassive exterior; but this was natural to him, and was but the outward sign of his even and judicial habit of mind.
No; there was no doubt that my startling news had left him unmoved, and this must be for one of two reasons: either he already knew all that I had told him (which was perfectly possible), or he had some other and better means of explaining the crime. I was turning over these two alternatives, not unobserved by my watchful colleague, when Polton entered the room; a broad grin was on his face, and a drawing-board, that he carried like a tray, bore twenty-four neatly turned boxwood pieces.
Thorndyke at once entered into the unspoken jest that beamed from the countenance of his subordinate.
"Here is Polton with a problem for you, Jervis," he said. "He assumes that I have invented a new parlour game, and has been trying to work out the moves. Have you succeeded yet, Polton?"
"No, sir, I haven't; but I suspect that one of the players will be a man in a wig and gown."
"Perhaps you are right," said Thorndyke; "but that doesn't take you very far. Let us hear what Dr. Jervis has to say."
"I can make nothing of them," I answered. "Polton showed me the drawing this morning, and then was terrified lest he had committed a breach of confidence, and I have been trying ever since, without a glimmer of success, to guess what they can be for."
"H'm," grunted Thorndyke, as he sauntered up and down the room, teacup in hand, "to guess, eh? I like not that word 'guess' in the mouth of a man of science. What do you mean by a 'guess'?"
His manner was wholly facetious, but I professed to take his question seriously, and replied—
"By a guess, I mean a conclusion arrived at without data."
"Impossible!" he exclaimed, with mock sternness. "Nobody but an utter fool arrives at a conclusion without data."
"Then I must revise my definition instantly," I rejoined. "Let us say that a guess is a conclusion drawn from insufficient facts."
"That is better," said he; "but perhaps it would be better still to say that a guess is a particular and definite conclusion deduced from facts which properly yield only a general and indefinite one. Let us take an instance," he continued. "Looking out of the window, I see a man walking round Paper Buildings. Now suppose I say, after the fashion of the inspired detective of the romances, 'That man is a stationmaster or inspector,' that would be a guess. The observed facts do not yield the conclusion, though they do warrant a conclusion less definite and more general."
"You'd have been right though, sir!" exclaimed Polton, who had stepped forward with me to examine the unconscious subject of the demonstration. "That gent used to be the stationmaster at Camberwell. I remember him well."
The little man was evidently greatly impressed.
"I happen to be right, you see," said Thorndyke; "but I might as easily have been wrong."
"You weren't though, sir," said Polton. "You spotted him at a glance."
In his admiration of the result he cared not a fig for the correctness of the means by which it had been attained.
"Now why do I suggest that he is a stationmaster?" pursued Thorndyke, disregarding his assistant's comment.
"I suppose you were looking at his feet," I answered. "I seem to have noticed that peculiar, splay-footed gait in stationmasters, now that you mention it."
"Quite so. The arch of the foot has given way; the plantar ligaments have become stretched and the deep calf muscles weakened. Then, since bending of the weakened arch causes discomfort, the feet have become turned outwards, by which the bending of the foot is reduced to a minimum; and as the left foot is the more flattened, so it is turned out more than the right. Then the turning out of the toes causes the legs to splay outward from the knees downwards—a very conspicuous condition in a tall man like this one—and you notice that the left leg splays out more than the other.
"But we know that depression of the arch of the foot is brought about by standing for long periods. Continuous pressure on a living structure weakens it, while intermittent pressure strengthens it; so the man who stands on his feet continuously develops a flat instep and a weak calf, while the professional dancer or runner acquires a high instep and a strong calf. Now there are many occupations which involve prolonged standing and so induce the condition of flat foot: waiters, hall-porters, hawkers, policemen, shop-walkers, salesmen, and station officials are examples. But the waiter's gait is characteristic—a quick, shuffling walk which enables him to carry liquids without spilling them. This man walks with a long, swinging stride; he is obviously not a waiter. His dress and appearance in general exclude the idea of a hawker or even a hall-porter; he is a man of poor physique and so cannot be a policeman. The shop-walker or salesman is accustomed to move in relatively confined spaces, and so acquires a short, brisk step, and his dress tends to rather exuberant smartness; the station official patrols long platforms, often at a rapid pace, and so tends to take long strides, while his dress is dignified and neat rather than florid. The last-mentioned characteristics, you see, appear in the subject of our analysis; he agrees with the general description of a stationmaster. But if we therefore conclude that he is a stationmaster, we fall into the time-honoured fallacy of the undistributed middle term—the fallacy that haunts all brilliant guessers, including the detective, not only of romance, but too often also of real life. All that the observed facts justify us in inferring is that this man is engaged in some mode of life that necessitates a good deal of standing; the rest is mere guess-work."
"It's wonderful," said Polton, gazing at the now distant figure; "perfectly wonderful. I should never have known he was a stationmaster." With this and a glance of deep admiration at his employer, he took his departure.
"You will also observe," said Thorndyke, with a smile, "that a fortunate guess often brings more credit than a piece of sound reasoning with a less striking result."
"Yes, that is unfortunately the case, and it is certainly true in the present instance. Your reputation, as far as Polton is concerned, is now firmly established even if it was not before. In his eyes you are a wizard from whom nothing is hidden. But to return to these little pieces, as I must call them, for the lack of a better name. I can form no hypothesis as to their use. I seem to have no 'departure,' as the nautical phrase goes, from which to start an inquiry. I haven't even the material for guess-work. Ought I to be able to arrive at any opinion on the subject?"
Thorndyke picked up one of the pieces, fingering it delicately and inspecting with a critical eye the flat base on which it stood, and reflected for a few moments.
"It is easy to trace a connection when one knows all the facts," he said at length, "but it seems to me that you have the materials from which to form a conjecture. Perhaps I am wrong, but I think, when you have had more experience, you will find yourself able to work out a problem of this kind. What is required is constructive imagination and a rigorous exactness in reasoning. Now, you are a good reasoner, and you have recently shown me that you have the necessary imagination; you merely lack experience in the use of your faculties. When you learn my purpose in having these things made—as you will before long—you will probably be surprised that their use did not occur to you. And now let us go forth and take a brisk walk to refresh ourselves (or perhaps I should say myself) after the day's labour."
XI. The Ambush
"I am going to ask for your collaboration in another case," said Thorndyke, a day or two later. "It appears to be one of suicide, but the
solicitors to the 'Griffin' office have asked me to go down to the place, which is in the neighbourhood of Barnet, and be present at the post-mortem and the inquest. They have managed to arrange that the inquest shall take place directly after the post-mortem, so that we shall be able to do the whole business in a single visit."
"Is the case one of any intricacy?" I asked.
"I don't think so," he answered. "It looks like a common suicide; but you can never tell. The importance of the case at present arises entirely from the heavy insurance; a verdict of suicide will mean a gain of ten thousand pounds to the 'Griffin,' so, naturally, the directors are anxious to get the case settled and not inclined to boggle over a little expense."
"Naturally. And when will the expedition take place?" I asked.
"The inquest is fixed for to-morrow—what is the matter? Does that fall foul of any arrangement of yours?"
"Oh, nothing of any importance," I replied hastily, deeply ashamed of the momentary change of countenance that my friend had been so quick to observe.
"Well, what is it?" persisted Thorndyke. "You have got something on."
"It is nothing, I tell you, but what can be quite easily arranged to suit your plans."
"Cherchez la—h'm?" queried Thorndyke, with an exasperating grin.
"Yes," I answered, turning as red as a pickled cabbage; "since you are so beastly inquisitive. Miss Gibson wrote, on behalf of Mrs. Hornby, asking me to dine with them en famille to-morrow evening, and I sent off an acceptance an hour ago."
"And you call that 'nothing of any importance'!" exclaimed Thorndyke. "Alas! and likewise alackaday (which is an approximately synonymous expression)! The age of chivalry is past, indeed. Of course you must keep your appointment; I can manage quite well alone."
"We shouldn't be back early enough for me to go to Kensington from the station, I suppose?"
"No; certainly not. I find that the trains are very awkward; we should not reach King's Cross until nearly one in the morning."
