THE DR. THORNDYKE TRILOGY (Forensic Science Mysteries). R. Austin Freeman

have forgotten him even for a single instant."

      "You can see him to-morrow, if you like," I said; and, casting my good resolutions to the winds, I added: "I shall be going to see him myself, and perhaps Dr. Thorndyke will go."

      "Would you let me call at the Temple and go with you? Should I be much in the way? It is rather an alarming thing to go to a prison alone."

      "It is not to be thought of," I answered. "If you will call at the Temple—it is on the way—we can drive to Holloway together. I suppose you are resolved to go? It will be rather unpleasant, as you are probably aware."

      "I am quite resolved. What time shall I come to the Temple?"

      "About two o'clock, if that will suit you."

      "Very well. I will be punctual; and now you must go or you will be caught."

      She pushed me gently towards the door and, holding out her hand, said—

      "I haven't thanked you half enough and I never can. Good-bye!"

      She was gone, and I stood alone in the street, up which yellowish wreaths of fog were beginning to roll. It had been quite clear and bright when I entered the house, but now the sky was settling down into a colourless grey, the light was failing and the houses dwindling into dim, unreal shapes that vanished at half their height. Nevertheless I stepped out briskly and strode along at a good pace, as a young man is apt to do when his mind is in somewhat of a ferment. In truth, I had a good deal to occupy my thoughts and, as will often happen both to young men and old, those matters that bore most directly upon my own life and prospects were the first to receive attention.

      What sort of relations were growing up between Juliet Gibson and me? And what was my position? As to hers, it seemed plain enough; she was wrapped up in Reuben Hornby and I was her very good friend because I was his. But for myself, there was no disguising the fact that I was beginning to take an interest in her that boded ill for my peace of mind.

      Never had I met a woman who so entirely realised my conception of what a woman should be, nor one who exercised so great a charm over me. Her strength and dignity, her softness and dependency, to say nothing of her beauty, fitted her with the necessary weapons for my complete and utter subjugation. And utterly subjugated I was—there was no use in denying the fact, even though I realised already that the time would presently come when she would want me no more and there would remain no remedy for me but to go away and try to forget her.

      But was I acting as a man of honour? To this I felt I could fairly answer "yes," for I was but doing my duty, and could hardly act differently if I wished to. Besides, I was jeopardising no one's happiness but my own, and a man may do as he pleases with his own happiness. No; even Thorndyke could not accuse me of dishonourable conduct.

      Presently my thoughts took a fresh turn and I began to reflect upon what I had heard concerning Mr. Hornby. Here was a startling development, indeed, and I wondered what difference it would make in Thorndyke's hypothesis of the crime. What his theory was I had never been able to guess, but as I walked along through the thickening fog I tried to fit this new fact into our collection of data and determine its bearings and significance.

      In this, for a time, I failed utterly. The red thumb-mark filled my field of vision to the exclusion of all else. To me, as to everyone else but Thorndyke, this fact was final and pointed to a conclusion that was unanswerable. But as I turned the story of the crime over and over, there came to me presently an idea that set in motion a new and very startling train of thought.

      Could Mr. Hornby himself be the thief? His failure appeared sudden to the outside world, but he must have seen difficulties coming. There, indeed, was the thumb-mark on the leaf which he had torn from his pocket-block. Yes! but who had seen him tear it off? No one. The fact rested on his bare statement.

      But the thumb-mark? Well, it was possible (though unlikely)—still possible—that the mark might have been made accidentally on some previous occasion and forgotten by Reuben, or even unnoticed. Mr. Hornby had seen the "Thumbograph," in fact his own mark was in it, and so would have had his attention directed to the importance of finger-prints in identification. He might have kept the marked paper for future use, and, on the occasion of the robbery, pencilled a dated inscription on it, and slipped it into the safe as a sure means of diverting suspicion. All this was improbable in the highest degree, but then so was every other explanation of the crime; and as to the unspeakable baseness of the deed, what action is too base for a gambler in difficulties?

      I was so much excited and elated by my own ingenuity in having formed an intelligible and practicable theory of the crime, that I was now impatient to reach home that I might impart my news to Thorndyke and see how they affected him. But as I approached the centre of the town the fog grew so dense that all my attention was needed to enable me to thread my way safely through the traffic; while the strange, deceptive aspect that it lent to familiar objects and the obliteration of landmarks made my progress so slow that it was already past six o'clock when I felt my way down Middle Temple Lane and crept through Crown Office Row towards my colleague's chambers.

      On the doorstep I found Polton peering with anxious face into the blank expanse of yellow vapour.

      "The Doctor's late, sir," said he. "Detained by the fog, I expect. It must be pretty thick in the Borough."

      (I may mention that, to Polton, Thorndyke was The Doctor. Other inferior creatures there were, indeed, to whom the title of "doctor" in a way, appertained; but they were of no account in Polton's eyes. Surnames were good enough for them.)

      "Yes, it must be," I replied, "judging by the condition of the Strand."

      I entered and ascended the stairs, glad enough of the prospect of a warm and well-lighted room after my comfortless groping in the murky streets, and Polton, with a final glance up and down the walk reluctantly followed.

      "You would like some tea, sir, I expect?" said he, as he let me in (though I had a key of my own now).

      I thought I should, and he accordingly set about the preparations in his deft methodical way, but with an air of abstraction that was unusual with him.

      "The Doctor said he should be home by five," he remarked, as he laid the tea-pot on the tray.

      "Then he is a defaulter," I answered. "We shall have to water his tea."

      "A wonderful punctual man, sir, is the Doctor," pursued Polton. "Keeps his time to the minute, as a rule, he does."

      "You can't keep your time to a minute in a 'London Particular,'" I said a little impatiently, for I wished to be alone that I might think over matters, and Polton's nervous flutterings irritated me somewhat. He was almost as bad as a female housekeeper.

      The little man evidently perceived my state of mind, for he stole away silently, leaving me rather penitent and ashamed, and, as I presently discovered on looking out of the window, resumed his vigil on the doorstep. From this coign of vantage he returned after a time to take away the tea-things; and thereafter, though it was now dark as well as foggy, I could hear him softly flitting up and down the stairs with a gloomy stealthiness that at length reduced me to a condition as nervously apprehensive as his own.

A Suspicious Accident

       Table of Contents

      The Temple clock had announced in soft and confidential tones that it was a quarter to seven, in which statement it was stoutly supported by its colleague on our mantelpiece, and still there was no sign of Thorndyke. It was really a little strange, for he was the soul of punctuality, and moreover, his engagements were of such a kind as rendered punctuality possible. I was burning with impatience to impart my news to him, and this fact, together with the ghostly proceedings of Polton, worked me up to a state of nervous tension that rendered either rest or thought equally impossible. I looked out of the window at the lamp below, glaring redly through the fog, and then, opening the door, went out on to the landing to listen.
