“Toby lives at No. 7 on the left here.” He moved slowly forward with his candle among the queer animal family which he had gathered round him. In the uncertain, shadowy light I could see dimly that there were glancing, glimmering eyes peeping down at us from every cranny and corner. Even the rafters above our heads were lined by solemn fowls, who lazily shifted their weight from one leg to the other as our voices disturbed their slumbers. Toby proved to be an ugly, long-haired, lop-eared creature, half spaniel and half lurcher, brown-and-white in colour, with a very clumsy waddling gait. It accepted after some hesitation a lump of sugar which the old naturalist handed to me, and, having thus sealed an alliance, it followed me to the cab, and made no difficulties about accompanying me. It had just struck three on the Palace clock when I found myself back once more at Pondicherry Lodge. The ex-prize-fighter McMurdo had, I found, been arrested as an accessory, and both he and Mr. Sholto had been marched off to the station. Two constables guarded the narrow gate, but they allowed me to pass with the dog on my mentioning the detective’s name. Holmes was standing on the door-step, with his hands in his pockets, smoking his pipe. “Ah, you have him there!” said he. “Good dog, then! Athelney Jones has gone. We have had an immense display of energy since you left. He has arrested not only friend Thaddeus, but the gatekeeper, the housekeeper, and the Indian servant. We have the place to ourselves, but for a sergeant upstairs. Leave the dog here, and come up.” We tied Toby to the hall table, and re-ascended the stairs. The room was as he had left it, save that a sheet had been draped over the central figure. A weary-looking police-sergeant reclined in the corner. “Lend me your bull’s-eye, sergeant,” said my companion. “Now tie this bit of card round my neck, so as to hang it in front of me. Thank you. Now I must kick off my boots and stockings.—Just you carry them down with you, Watson. I am going to do a little climbing. And dip my handkerchief into the creasote. That will do. Now come up into the garret with me for a moment.” We clambered up through the hole. Holmes turned his light once more upon the footsteps in the dust. “I wish you particularly to notice these footmarks,” he said. “Do you observe anything noteworthy about them?” “They belong,” I said, “to a child or a small woman.” “Apart from their size, though. Is there nothing else?” “They appear to be much as other footmarks.” “Not at all. Look here! This is the print of a right foot in the dust. Now I make one with my naked foot beside it. What is the chief difference?” “Your toes are all cramped together. The other print has each toe distinctly divided.” “Quite so. That is the point. Bear that in mind. Now, would you kindly step over to that flap-window and smell the edge of the wood-work? I shall stay here, as I have this handkerchief in my hand.”
