and poured out a stream of remarks, while Holmes threw
in an occasional question or interjection. Colonel Ross leaned back with
his arms folded and his hat tilted over his eyes, while I listened with
interest to the dialogue of the two detectives. Gregory was formulating
his theory, which was almost exactly what Holmes had foretold in the
train.

"The net is drawn pretty close round Fitzroy Simpson," he remarked, "and
I believe myself that he is our man. At the same time I recognize that
the evidence is purely circumstantial, and that some new development may
upset it."

"How about Straker's knife?"

"We have quite come to the conclusion that he wounded himself in his
fall."

"My friend Dr. Watson made that suggestion to me as we came down. If so,
it would tell against this man Simpson."

"Undoubtedly. He has neither a knife nor any sign of a wound. The
evidence against him is certainly very strong. He had a great interest
in the disappearance of the favorite. He lies under suspicion of having
poisoned the stable-boy, he was undoubtedly out in the storm, he was
armed with a heavy stick, and his cravat was found in the dead man's
hand. I really think we have enough to go before a jury."

Holmes shook his head. "A clever counsel would tear it all to rags,"
said he. "Why should he take the horse out of the stable? If he wished
to injure it why could he not do it there? Has a duplicate key been
found in his possession? What chemist sold him the powdered opium? Above
all, where could he, a stranger to the district, hide a horse, and such
a horse as this? What is his own explanation as to the paper which he
wished the maid to give to the stable-boy?"

"He says that it was a ten-pound note. One was found in his purse. But
your other difficulties are not so formidable as they seem. He is not
a stranger to the district. He has twice lodged at Tavistock in the
summer. The opium was probably brought from London. The key, having
served its purpose, would be hurled away. The horse may be at the bottom
of one of the pits or old mines upon the moor."

"What does he say about the cravat?"

"He acknowledges that it is his, and declares that he had lost it. But a
new element has been introduced into the case which may account for his
leading the horse from the stable."

Holmes pricked up his ears.

"We have found traces which show that a party of gypsies encamped on
Monday night within a mile of the spot where the murder t
