His head had been shattered by a savage blow from some heavy weapon, and he was wounded on the thigh, where there was a long, clean cut, inflicted evidently by some very sharp instrument. It was clear, however, that Straker had defended himself vigorously against his assailants, for in his right hand he held a small knife, which was clotted with blood up to the handle, while in his left he clasped a red and black silk cravat, which was recognized by the maid as having been worn on the preceding evening by the stranger who had visited the stables. Hunter, on recovering from his stupor, was also quite positive as to the ownership of the cravat. He was equally certain that the same stranger had, while standing at the window, drugged his curried mutton, and so deprived the stables of their watchman. As to the missing horse, there were abundant proofs in the mud which lay at the bottom of the fatal hollow that he had been there at the time of the struggle. But from that morning he has disappeared, and although a large reward has been offered, and all the gypsies of Dartmoor are on the alert, no news has come of him. Finally, an analysis has shown that the remains of his supper left by the stable-lad contain an appreciable quantity of powdered opium, while the people at the house partook of the same dish on the same night without any ill effect.
"Those are the main facts of the case, stripped of all surmise, and stated as baldly as possible. I shall now recapitulate what the police have done in the matter.
"Inspector Gregory, to whom the case has been committed, is an extremely competent officer. Were he but gifted with imagination he might rise to great heights in his profession. On his arrival he promptly found and arrested the man upon whom suspicion naturally rested. There was little difficulty in finding him, for he inhabited one of those villas which I have mentioned. His name, it appears, was Fitzroy Simpson. He was a man of excellent birth and education, who had squandered a fortune upon the turf, and who lived now by doing a little quiet and genteel book-making in the sporting clubs of London. An examination of his betting-book shows that bets to the amount of five thousand pounds had been registered by him against the favorite. On being arrested he volunteered that statement that he had come down to Dartmoor in the hope of getting some information about the King's Pyland horses, and also about Desborough, the second favorite, which was in charge of Silas Brown at the Mapleton stables. He did not attempt to deny that he had acted as described upon the evening before, but declared that he had no sinister designs, and had simply wished to obtain first-hand information. When confronted with his cravat, he turned very pale, and was utterly unable to account for its presence in the hand of the murdered man. His wet clothing showed that he had been out in the storm of the night before, and his stick, which was a Penang-lawyer weighted with lead, was just such a weapon as might, by repeated blows, have inflicted the terrible injuries to which the trainer had succumbed. On the other hand, there was no wound upon his person, while the state of Straker's knife would show that one at least of his assailants must bear his mark upon him. There you have it all in a nutshell, Watson, and if you can give me any light I shall be infinitely obliged to you."
I had listened with the greatest interest to the statement which Holmes, with characteristic clearness, had laid before me. Though most of the facts were familiar to me, I had not sufficiently appreciated their relative importance, nor their connection to each other.
"Is in not possible," I suggested, "that the incised would upon Straker may have been caused by his own knife in the convulsive struggles which follow any brain injury?"
"It is more than possible; it is probable," said Holmes. "In that case one of the main points in favor of the accused disappears."
"And yet," said I, "even now I fail to understand what the theory of the police can be."
"I am afraid that whatever theory we state has very grave objections to it," returned my companion.
