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

that so strongly engages a man's sympathy.

      In short, I realised that, had there been no such person as Reuben Hornby, I should have viewed Miss Gibson with uncommon interest.

      But, unfortunately, Reuben Hornby was a most palpable reality, and, moreover, the extraordinary difficulties of his position entitled him to very special consideration by any man of honour. It was true that Miss Gibson had repudiated any feelings towards Reuben other than those of old-time friendship; but young ladies are not always impartial judges of their own feelings, and, as a man of the world, I could not but have my own opinion on the matter—which opinion I believed to be shared by Thorndyke. The conclusions to which my cogitations at length brought me were: first, that I was an egotistical donkey, and, second, that my relations with Miss Gibson were of an exclusively business character and must in future be conducted on that basis, with the added consideration that I was the confidential agent, for the time being, of Reuben Hornby, and in honour bound to regard his interests as paramount.

      "I am hoping," said Thorndyke, as he held out his hand for my teacup, "that these profound reflections of yours are connected with the Hornby affair; in which case I should expect to hear that the riddle is solved and the mystery made plain."

      "Why should you expect that?" I demanded, reddening somewhat, I suspect, as I met his twinkling eye. There was something rather disturbing in the dry, quizzical smile that I encountered and the reflection that I had been under observation, and I felt as much embarrassed as I should suppose a self-conscious water-flea might feel on finding itself on the illuminated stage of a binocular microscope.

      "My dear fellow," said Thorndyke, "you have not spoken a word for the last quarter of an hour; you have devoured your food with the relentless regularity of a sausage-machine, and you have, from time to time, made the most damnable faces at the coffee-pot—though there I'll wager the coffee-pot was even with you, if I may judge by the presentment that it offers of my own countenance."

      I roused myself from my reverie with a laugh at Thorndyke's quaint conceit and a glance at the grotesquely distorted reflection of my face in the polished silver.

      "I am afraid I have been a rather dull companion this morning," I admitted apologetically.

      "By no means," replied Thorndyke, with a grin. "On the contrary, I have found you both amusing and instructive, and I only spoke when I had exhausted your potentialities as a silent entertainer."

      "You are pleased to be facetious at my expense," said I.

      "Well, the expense was not a very heavy one," he retorted. "I have been merely consuming a by-product of your mental activity—Hallo! that's Anstey already."

      A peculiar knock, apparently delivered with the handle of a walking-stick on the outer door, was the occasion of this exclamation, and as Thorndyke sprang up and flung the door open, a clear, musical voice was borne in, the measured cadences of which proclaimed at once the trained orator.

      "Hail, learned brother!" it exclaimed. "Do I disturb you untimely at your studies?" Here our visitor entered the room and looked round critically. "'Tis even so," he declared. "Physiological chemistry and its practical applications appears to be the subject. A physico-chemical inquiry into the properties of streaky bacon and fried eggs. Do I see another learned brother?"

      He peered keenly at me through his pince-nez, and I gazed at him in some embarrassment.

      "This is my friend Jervis, of whom you have heard me speak," said Thorndyke. "He is with us in this case, you know."

      "The echoes of your fame have reached me, sir," said Anstey, holding out his hand. "I am proud to know you. I should have recognised you instantly from the portrait of your lamented uncle in Greenwich Hospital."

      "Anstey is a wag, you understand," explained Thorndyke, "but he has lucid intervals. He'll have one presently if we are patient."

      "Patient!" snorted our eccentric visitor, "it is I who need to be patient when I am dragged into police courts and other sinks of iniquity to plead for common thieves and robbers like a Kennington Lane advocate."

      "You've been talking to Lawley, I see," said Thorndyke.

      "Yes, and he tells me that we haven't a leg to stand upon."

      "No, we've got to stand on our heads, as men of intellect should. But Lawley knows nothing about the case."

      "He thinks he knows it all," said Anstey.

      "Most fools do," retorted Thorndyke. "They arrive at their knowledge by intuition—a deuced easy road and cheap travelling too. We reserve our defence—I suppose you agree to that?"

      "I suppose so. The magistrate is sure to commit unless you have an unquestionable alibi."

      "We shall put in an alibi, but we are not depending on it."

      "Then we had better reserve our defence," said Anstey; "and it is time that we wended on our pilgrimage, for we are due at Lawley's at half-past ten. Is Jervis coming with us?"

      "Yes, you'd better come," said Thorndyke. "It's the adjourned hearing of poor Hornby's case, you know. There won't be anything done on our side, but we may be able to glean some hint from the prosecution."

      "I should like to hear what takes place, at any rate," I said, and we accordingly sallied forth together in the direction of Lincoln's Inn, on the north side of which Mr. Lawley's office was situated.

      "Ah!" said the solicitor, as we entered, "I am glad you've come; I was getting anxious—it doesn't do to be late on these occasions, you know. Let me see, do you know Mr. Walter Hornby? I don't think you do." He presented Thorndyke and me to our client's cousin, and as we shook hands, we viewed one another with a good deal of mutual interest.

      "I have heard about you from my aunt," said he, addressing himself more particularly to me. "She appears to regard you as a kind of legal Maskelyne and Cooke. I hope, for my cousin's sake, that you will be able to work the wonders that she anticipates. Poor old fellow! He looks pretty bad, doesn't he?"

      I glanced at Reuben, who was at the moment talking to Thorndyke, and as he caught my eye he held out his hand with a warmth that I found very pathetic. He seemed to have aged since I had last seen him, and was pale and rather thinner, but he was composed in his manner and seemed to me to be taking his trouble very well on the whole.

      "Cab's at the door, sir," a clerk announced.

      "Cab," repeated Mr. Lawley, looking dubiously at me; "we want an omnibus."

      "Dr. Jervis and I can walk," Walter Hornby suggested. "We shall probably get there as soon as you, and it doesn't matter if we don't."

      "Yes, that will do," said Mr. Lawley; "you two walk down together. Now let us go."

      We trooped out on to the pavement, beside which a four-wheeler was drawn up, and as the others were entering the cab, Thorndyke stood close beside me for a moment.

      "Don't let him pump you," he said in a low voice, without looking at me; then he sprang into the cab and slammed the door.

      "What an extraordinary affair this is," Walter Hornby remarked, after we had been walking in silence for a minute or two; "a most ghastly business. I must confess that I can make neither head nor tail of it."

      "How is that?" I asked.

      "Why, do you see, there are apparently only two possible theories of the crime, and each of them seems to be unthinkable. On the one hand there is Reuben, a man of the most scrupulous honour, as far as my experience of him goes, committing a mean and sordid theft for which no motive can be discovered—for he is not poor, nor pecuniarily embarrassed nor in the smallest degree avaricious. On the other hand, there is this thumb-print, which, in the opinion of the experts, is tantamount to the evidence of an eye-witness that he did commit the theft. It is positively bewildering. Don't you think so?"

      "As you put it," I answered, "the case is extraordinarily puzzling."

      "But how else would you put it?" he demanded,
