The water-pipe feels pretty firm. Here goes, anyhow."
There was a scuffling of feet, and the lantern began to come steadily down the side of the wall. Then with a light spring he came on to the barrel, and from there to the earth.
"It was easy to follow him," he said, drawing on his stockings and boots. "Tiles were loosened the whole way along, and in his hurry he had dropped this. It confirms my diagnosis, as you doctors express it."
The object which he held up to me was a small pocket or pouch woven out of colored grasses and with a few tawdry beads strung round it. In shape and size it was not unlike a cigarette-case. Inside were half a dozen spines of dark wood, sharp at one end and rounded at the other, like that which had struck Bartholomew Sholto.
"They are hellish things," said he. "Look out that you don't prick yourself. I'm delighted to have them, for the chances are that they are all he has. There is the less fear of you or me finding one in our skin before long. I would sooner face a Martini bullet, myself. Are you game for a six-mile trudge, Watson?"
"Certainly," I answered.
"Your leg will stand it?"
"Oh, yes."
"Here you are, doggy! Good old Toby! Smell it, Toby, smell it!" He pushed the creasote handkerchief under the dog's nose, while the creature stood with its fluffy legs separated, and with a most comical cock to its head, like a connoisseur sniffing the bouquet of a famous vintage. Holmes then threw the handkerchief to a distance, fastened a stout cord to the mongrel's collar, and led him to the foot of the water-barrel. The creature instantly broke into a succession of high, tremulous yelps, and, with his nose on the ground, and his tail in the air, pattered off upon the trail at a pace which strained his leash and kept us at the top of our speed.
The east had been gradually whitening, and we could now see some distance in the cold gray light. The square, massive house, with its black, empty windows and high, bare walls, towered up, sad and forlorn, behind us. Our course led right across the grounds, in and out among the trenches and pits with which they were scarred and intersected. The whole place, with its scattered dirt-heaps and ill-grown shrubs, had a blighted, ill-omened look which harmonized with the black tragedy which hung over it.
On reaching the boundary wall Toby ran along, whining eagerly, underneath its shadow, and stopped finally in a corner screened by a young beech. Where the two walls joined, several bricks had been loosened, and the crevices left were worn down and rounded upon the lower side, as though they had frequently been used as a ladder. Holmes clambered up, and, taking the dog from me, he dropped it over upon the other side.
"There's the print of wooden-leg's hand," he remarked, as I mounted up beside him. "You see the slight smudge of blood upon the white plaster. What a lucky thing it is that we have had no very heavy rain since yesterday! The scent will lie upon the road in spite of their eight-and-twenty hours' start."
I confess that I had my doubts myself when I reflected upon the great traffic which had passed along the London road in the interval. My fears were soon appeased, however. Toby never hesitated or swerved, but waddled on in his peculiar rolling fashion. Clearly, the pungent smell of the creasote rose high above all other contending scents.
"Do not imagine," said Holmes, "that I depend for my success in this case upon the mere chance of one of these fellows having put his foot in the chemical. I have knowledge now which would enable me to trace them in many different ways. This, however, is the readiest and, since fortune has put it into our hands, I should be culpable if I neglected it. It has, however, prevented the case from becoming the pretty little intellectual problem which it at one time promised to be. There might have been some credit to be gained out of it, but for this too palpable clue."
"There is credit, and to spare," said I.
