"It is hollow," said Thorndyke. "You must have observed that, when I held it up to drain, the water trickled out through the hole at the pointed end."
"Yes, I noticed that."
"Now take it up and shake it."
I did so and felt some heavy object rattle inside it.
"There is some loose body inside it," I said, "which fits it pretty closely, as it moves only in the long diameter."
"Quite so; your description is excellent. And now, what is the nature of this projectile?"
"I should say it is a miniature shell or explosive bullet."
"Wrong!" said Thorndyke. "A very natural inference, but a wrong one."
"Then what is the thing?" I demanded, my curiosity still further aroused.
"I will show you," he replied. "It is something much more subtle than an explosive bullet—which would really be a rather crude appliance—admirably thought out and thoroughly well executed. We have to deal with a most ingenious and capable man."
I was fain to laugh at his enthusiastic appreciation of the methods of his would-be assassin, and the humour of the situation then appeared to dawn on him, for he said, with an apologetic smile—
"I am not expressing approval, you must understand, but merely professional admiration. It is this class of criminal that creates the necessity for my services. He is my patron, so to speak; my ultimate employer. For the common crook can be dealt with quite efficiently by the common policeman!"
While he was speaking he had been fitting the little cylinder between two pads of tissue-paper in the vice, which he now screwed up tight. Then, with the fine metal saw, he began to cut the projectile, lengthwise, into two slightly unequal parts. This operation took some time, especially since he was careful not to cut the loose body inside, but at length the section was completed and the interior of the cylinder exposed, when he released it from the vice and held it up before me with an expression of triumph.
"Now, what do you make it?" he demanded.
I took the object in my fingers and looked at it closely, but was at first more puzzled than before. The loose body I now saw to be a cylinder of lead about half an inch long, accurately fitting the inside of the cylinder but capable of slipping freely backwards and forwards. The steel point which I had noticed in the hole at the apex of the conical end, was now seen to be the pointed termination of a slender steel rod which projected fully an inch into the cavity of the cylinder, and the conical end itself was a solid mass of lead.
"Well?" queried Thorndyke, seeing that I was still silent.
"You tell me it is not an explosive bullet," I replied, "otherwise I should have been confirmed in that opinion. I should have said that the percussion cap was carried by this lead plunger and struck on the end of that steel rod when the flight of the bullet was suddenly arrested."
"Very good indeed," said Thorndyke. "You are right so far that this is, in fact, the mechanism of a percussion shell.
"But look at this. You see this little rod was driven inside the bullet when the latter struck the wall. Let us replace it in its original position."
He laid the end of a small flat file against the end of the rod and pressed it firmly, when the rod slid through the hole until it projected an inch beyond the apex of the cone. Then he handed the projectile back to me.
A single glance at the point of the steel rod made the whole thing clear, and I gave a whistle of consternation; for the "rod" was a fine tube with a sharply pointed end.
"The infernal scoundrel!" I exclaimed; "it is a hypodermic needle."
"Yes. A veterinary hypodermic, of extra large bore. Now you see the subtlety and ingenuity of the whole thing. If he had had a reasonable chance he would certainly have succeeded."
"You speak quite regretfully," I said, laughing again at the oddity of his attitude towards the assassin.
"Not at all," he replied. "I have the character of a single-handed player, but even the most self-reliant man can hardly make a post-mortem on himself. I am merely appreciating an admirable piece of mechanical design most efficiently carried out. Observe the completeness of the thing, and the way in which all the necessities of the case are foreseen and met. This projectile was discharged from a powerful air-gun—the walking-stick form—provided with a force-pump and key. The barrel of that gun was rifled."
"How do you know that?" I asked.
"Well, to begin with, it would be useless to fit a needle to the projectile unless the latter was made to travel with the point forwards; but there is direct evidence that the barrel was rifled. You notice the little square projection on the back surface of the cylinder. That was evidently made to fit a washer or wad—probably a thin plate of soft metal which would be driven by the pressure from behind into the grooves of the rifling and thus give a spinning motion to the bullet. When the latter left the barrel, the wad would drop off, leaving it free."
"I see. I was wondering what the square projection was for. It is, as you say, extremely ingenious."
"Highly ingenious," said Thorndyke, enthusiastically, "and so is the whole device. See how perfectly it would have worked but for a mere fluke and for the complication of your presence. Supposing that I had been alone, so that he could have approached to a shorter distance. In that case he would not have missed, and the thing would have been done. You see how it was intended to be done, I suppose?"
"I think so," I answered; "but I should like to hear your account of the process."
"Well, you see, he first finds out that I am returning by a late train—which he seems to have done—and he waits for me at the terminus. Meanwhile he fills the cylinder with a solution of a powerful alkaloidal poison, which is easily done by dipping the needle into the liquid and sucking at the small hole near the back end, when the piston will be drawn up and the liquid will follow it. You notice that the upper side of the piston is covered with vaseline—introduced through the hole, no doubt—which would prevent the poison from coming out into the mouth, and make the cylinder secure from leakage. On my arrival, he follows me on his bicycle until I pass through a sufficiently secluded neighbourhood. Then he approaches me, or passes me and waits round a corner, and shoots at pretty close range. It doesn't matter where he hits me; all parts are equally vital, so he can aim at the middle of my back. Then the bullet comes spinning through the air point foremost; the needle passes through the clothing and enters the flesh, and, as the bullet is suddenly stopped, the heavy piston flies down by its own great momentum and squirts out a jet of the poison into the tissues. The bullet then disengages itself and drops on to the ground.
"Meanwhile, our friend has mounted his bicycle and is off, and when I feel the prick of the needle, I turn, and, without stopping to look for the bullet, immediately give chase. I am, of course, not able to overtake a man on a racing machine, but still I follow him some distance. Then the poison begins to take effect—the more rapidly from the violent exercise—and presently I drop insensible. Later on, my body is found. There are no marks of violence, and probably the needle-puncture escapes observation at the post-mortem, in which case the verdict will be death from heart-failure. Even if the poison and the puncture are discovered, there is no clue. The bullet lies some streets away, and is probably picked up by some boy or passing stranger, who cannot conjecture its use, and who would never connect it with the man who was found dead. You will admit that the whole plan has been worked out with surprising completeness and foresight."
"Yes," I answered; "there is no doubt that the fellow is a most infernally clever scoundrel. May I ask if you have any idea who he is?"
"Well," Thorndyke replied, "seeing that, as Carlyle has unkindly pointed out, clever people are not in an overwhelming majority, and that, of the clever people whom I know, only a very few are interested in my immediate demise, I am able to form a fairly probable conjecture."
"And what do you mean to do?"
"For the present I shall maintain an attitude of masterly inactivity and avoid the night air."
&nbs
p; "But, surely," I exclaimed, "you will take some measures to protect yourself against attempts of this kind. You can hardly doubt now that your accident in the fog was really an attempted murder."
"I never did doubt it, as a matter of fact, although I prevaricated at the time. But I have not enough evidence against this man at present, and, consequently, can do nothing but show that I suspect him, which would be foolish. Whereas, if I lie low, one of two things will happen; either the occasion for my removal (which is only a temporary one) will pass, or he will commit himself—will put a definite clue into my hands. Then we shall find the air-cane, the bicycle, perhaps a little stock of poison, and certain other trifles that I have in my mind, which will be good confirmatory evidence, though insufficient in themselves. And now, I think, I must really adjourn this meeting, or we shall be good for nothing to-morrow."
XII. It Might Have Been
It was now only a week from the date on which the trial was to open. In eight days the mystery would almost certainly be solved (if it was capable of solution), for the trial promised to be quite a short one, and then Reuben Hornby would be either a convicted felon or a free man, clear of the stigma of the crime.
For several days past, Thorndyke had been in almost constant possession of the laboratory, while his own small room, devoted ordinarily to bacteriology and microscopical work was kept continually locked; a state of things that reduced Polton to a condition of the most extreme nervous irritation, especially when, as he told me indignantly, he met Mr. Anstey emerging from the holy of holies, grinning and rubbing his hands and giving utterance to genial but unparliamentary expressions of amused satisfaction.
I had met Anstey on several occasions lately, and each time liked him better than the last; for his whimsical, facetious manner covered a nature (as it often does) that was serious and thoughtful; and I found him, not only a man of considerable learning, but one also of a lofty standard of conduct. His admiration for Thorndyke was unbounded, and I could see that the two men collaborated with the utmost sympathy and mutual satisfaction.
But although I regarded Mr. Anstey with feelings of the liveliest friendship, I was far from gratified when, on the morning of which I am writing, I observed him from our sitting-room window crossing the gravelled space from Crown Office Row and evidently bearing down on our chambers. For the fact is that I was awaiting the arrival of Juliet, and should greatly have preferred to be alone at the moment, seeing that Thorndyke had already gone out. It is true that my fair enslaver was not due for nearly half-an-hour, but then, who could say how long Anstey would stay, or what embarrassments might arise from my efforts to escape? By all of which it may be perceived that my disease had reached a very advanced stage, and that I was unequal to those tactics of concealment that are commonly attributed to the ostrich.
A sharp rap of the knocker announced the arrival of the disturber of my peace, and when I opened the door Anstey walked in with the air of a man to whom an hour more or less is of no consequence whatever. He shook my hand with mock solemnity, and, seating himself upon the edge of the table, proceeded to roll a cigarette with exasperating deliberation.
"I infer," said he, "that our learned brother is practising parlour magic upstairs, or peradventure he has gone on a journey?"
"He has a consultation this morning," I answered. "Was he expecting you?"
"Evidently not, or he would have been here. No, I just looked in to ask a question about the case of your friend Hornby. You know it comes on for trial next week?"
"Yes; Thorndyke told me. What do you think of Hornby's prospects? Is he going to be convicted, or will he get an acquittal?"
"He will be entirely passive," replied Anstey, "but we"—here he slapped his chest impressively—"are going to secure an acquittal. You will be highly entertained, my learned friend, and Mr. The Enemy will be excessively surprised." He inspected the newly-made cigarette with a critical air and chuckled softly.
"You seem pretty confident," I remarked.
"I am," he answered, "though Thorndyke considers failure possible—which, of course, it is if the jury-box should chance to be filled with microcephalic idiots and the judge should prove incapable of understanding simple technical evidence. But we hope that neither of these things will happen, and, if they do not, we feel pretty safe. By the way, I hope I am not divulging your principal's secrets?"
"Well," I replied, with a smile, "you have been more explicit than Thorndyke ever has."
"Have I?" he exclaimed, with mock anxiety; "then I must swear you to secrecy. Thorndyke is so very close—and he is quite right too. I never cease admiring his tactics of allowing the enemy to fortify and barricade the entrance that he does not mean to attack. But I see you are wishing me at the devil, so give me a cigar and I will go—though not to that particular destination."
"Will you have one of Thorndyke's special brand?" I asked malignantly.
"What! those foul Trichinopolies? Not while brown paper is to be obtained at every stationer's; I'd sooner smoke my own wig."
I tendered my own case, from which he selected a cigar with anxious care and much sniffing; then he bade me a ceremonious adieu and departed down the stairs, blithely humming a melody from the latest comic opera.
He had not left more than five minutes when a soft and elaborate rat-tat from the little brass knocker brought my heart into my mouth. I ran to the door and flung it open, revealing Juliet standing on the threshold.
"May I come in?" she asked. "I want to have a few words with you before we start."
I looked at her with some anxiety, for she was manifestly agitated, and the hand that she held out to me trembled.
"I am greatly upset, Dr. Jervis," she said, ignoring the chair that I had placed for her. "Mr. Lawley has been giving us his views of poor Reuben's case, and his attitude fills me with dismay."
"Hang Mr. Lawley!" I muttered, and then apologised hastily. "What made you go to him, Miss Gibson?"
"I didn't go to him; he came to us. He dined with us last night—he and Walter—and his manner was gloomy in the extreme. After dinner Walter took him apart with me and asked him what he really thought of the case. He was most pessimistic. 'My dear sir,' he said, 'the only advice I can give you is that you prepare yourself to contemplate disaster as philosophically as you can. In my opinion your cousin is almost certain to be convicted.' 'But,' said Walter, 'what about the defence? I understood that there was at least a plausible case.' Mr. Lawley shrugged his shoulders. 'I have a sort of alibi that will go for nothing, but I have no evidence to offer in answer to that of the prosecution, and no case; and I may say, speaking in confidence, that I do not believe there is any case. I do not see how there can be any case, and I have heard nothing from Dr. Thorndyke to lead me to suppose that he has really done anything in the matter.' Is this true, Dr. Jervis? Oh! do tell me the real truth about it! I have been so miserable and terrified since I heard this, and I was so full of hope before. Tell me, is it true? Will Reuben be sent to prison after all?"
In her agitation she laid her hands on my arm and looked up into my face with her grey eyes swimming with tears, and was so piteous, so trustful, and, withal, so bewitching that my reserve melted like snow before a July sun.
"It is not true," I answered, taking her hands in mine and speaking perforce in a low tone that I might not betray my emotion. "If it were, it would mean that I have wilfully deceived you, that I have been false to our friendship; and how much that friendship has been to me, no one but myself will ever know."
She crept a little closer to me with a manner at once penitent and wheedling.
"You are not going to be angry with me, are you? It was foolish of me to listen to Mr. Lawley after all you have told me, and it did look like a want of trust in you, I know. But you, who are so strong and wise, must make allowance for a woman who is neither. It is all so terrible that I am quite unstrung; but say you are not really displeased with me, for that would hurt me most of all."
Oh! Delilah! That c
oncluding stroke of the shears severed the very last lock, and left me—morally speaking—as bald as a billiard ball. Henceforth I was at her mercy and would have divulged, without a scruple, the uttermost secrets of my principal, but that that astute gentleman had placed me beyond the reach of temptation.
"As to being angry with you," I answered, "I am not, like Thorndyke, one to essay the impossible, and if I could be angry it would hurt me more than it would you. But, in fact, you are not to blame at all, and I am an egotistical brute. Of course you were alarmed and distressed; nothing could be more natural. So now let me try to chase away your fears and restore your confidence.
"I have told you what Thorndyke said to Reuben: that he had good hopes of making his innocence clear to everybody. That alone should have been enough."
"I know it should," murmured Juliet remorsefully; "please forgive me for my want of faith."
"But," I continued, "I can quote you the words of one to whose opinions you will attach more weight. Mr. Anstey was here less than half-an-hour ago—"
"Do you mean Reuben's counsel?"
"Yes."
"And what did he say? Oh, do tell me what he said."
"He said, in brief, that he was quite confident of obtaining an acquittal, and that the prosecution would receive a great surprise. He seemed highly pleased with his brief, and spoke with great admiration of Thorndyke."
"Did he really say that—that he was confident of an acquittal?" Her voice was breathless and unsteady, and she was clearly, as she had said, quite unstrung. "What a relief it is," she murmured incoherently; "and so very, very kind of you!" She wiped her eyes and laughed a queer, shaky little laugh; then, quite suddenly, she burst into a passion of sobbing.
Hardly conscious of what I did, I drew her gently towards me, and rested her head on my shoulder whilst I whispered into her ear I know not what words of consolation; but I am sure that I called her "dear Juliet," and probably used other expressions equally improper and reprehensible. Presently she recovered herself, and, having dried her eyes, regarded me somewhat shamefacedly, blushing hotly, but smiling very sweetly nevertheless.
