“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.”
“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 tomorrow.”

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
