Sir Arthur Conan Doyle: Memoirs of Sherlock Holmes

1. Adventure I: Silver Blaze (continued)

"I was already convinced, or almost convinced, that John Straker went down to the stables in the dead of the night and took out Silver Blaze. For what purpose? For a dishonest one, obviously, or why should he drug his own stable-boy? And yet I was at a loss to know why. There have been cases before now where trainers have made sure of great sums of money by laying against their own horses, through agents, and then preventing them from winning by fraud. Sometimes it is a pulling jockey. Sometimes it is some surer and subtler means. What was it here? I hoped that the contents of his pockets might help me to form a conclusion.

"And they did so. You cannot have forgotten the singular knife which was found in the dead man's hand, a knife which certainly no sane man would choose for a weapon. It was, as Dr. Watson told us, a form of knife which is used for the most delicate operations known in surgery. And it was to be used for a delicate operation that night. You must know, with your wide experience of turf matters, Colonel Ross, that it is possible to make a slight nick upon the tendons of a horse's ham, and to do it subcutaneously, so as to leave absolutely no trace. A horse so treated would develop a slight lameness, which would be put down to a strain in exercise or a touch of rheumatism, but never to foul play."

"Villain! Scoundrel!" cried the Colonel.

"We have here the explanation of why John Straker wished to take the horse out on to the moor. So spirited a creature would have certainly roused the soundest of sleepers when it felt the prick of the knife. It was absolutely necessary to do it in the open air."

"I have been blind!" cried the Colonel. "Of course that was why he needed the candle, and struck the match."
