He turned back with the inspector, while Holmes and I walked slowly across the moor. The sun was beginning to sink behind the stable of Mapleton, and the long, sloping plain in front of us was tinged with gold, deepening into rich, ruddy browns where the faded ferns and brambles caught the evening light. But the glories of the landscape were all wasted upon my companion, who was sunk in the deepest thought.

“It’s this way, Watson,” said he at last. “We may leave the question of who killed John Straker for the instant and confine ourselves to finding out what has become of the horse. Now, supposing that he broke away during or after the tragedy, where could he have gone to? The horse is a very gregarious creature. If left to himself his instincts would have been either to return to King’s Pyland or go over to Mapleton. Why should he run wild upon the moor? He would surely have been seen by now. And why should gypsies kidnap him? These people always clear out when they hear of trouble, for they do not wish to be pestered by the police. They could not hope to sell such a horse. They would run a great risk and gain nothing by taking him. Surely that is clear.”

“Where is he, then?”

“I have already said that he must have gone to King’s Pyland or to Mapleton. He is not at King’s Pyland. Therefore he is at Mapleton. Let us take that as a working hypothesis and see what it leads us to. This part of the moor, as the inspector remarked, is very hard and dry. But it falls away towards Mapleton, and you can see from here that there is a long hollow over yonder, which must have been very wet on Monday night. If our supposition is correct, then the horse must have crossed that, and there is the point where we should look for his tracks.”

We had been walking briskly during this conversation, and a few more minutes brought us to the hollow in question. At Holmes’s request I walked down the bank to the right, and he to the left, but I had not taken fifty paces before I heard him give a shout and saw him waving his hand to me. The track of a horse was plainly outlined in the soft earth in front of him, and the shoe which he took from his pocket exactly fitted the impression.

“See the value of imagination,” said Holmes. “It is the one quality which Gregory lacks. We imagined what might have happened, acted upon the supposition, and find ourselves justified. Let us proceed.”

We crossed the marshy bottom and passed over a quarter of a mile of dry, hard turf. Again the ground sloped, and again we came on the tracks. Then we lost them for half a mile, but only to pick them up once more quite close to Mapleton. It was Holmes who saw them first, and he stood pointing with a look of triumph upon his face. A man’s track was visible beside the horse’s.

“The horse was alone before,” I cried.

“Quite so. It was alone before. Hullo, what is this?”

The double track turned sharp off and took the direction of King’s Pyland. Holmes whistled, and we both followed along after it. His eyes were on the trail, but I happened to look a little to one side and saw to my surprise the same tracks coming back again in the opposite direction.

“One for you, Watson,” said Holmes when I pointed it out. “You have saved us a long walk, which would have brought us back on our own traces. Let us follow the return track.”

We had not to go far. It ended at the paving of asphalt which led up to the gates of the Mapleton stables. As we approached, a groom ran out from them.

“We don’t want any loiterers about here,” said he.

“I only wished to ask a question,” said Holmes, with his finger and thumb in his waistcoat pocket. “Should I be too early to see your master, Mr. Silas Brown, if I were to call at five o’clock to-morrow morning?”

“Bless you, sir, if anyone is about he will be, for he is always the first stirring. But here he is, sir, to answer your questions for himself. No, sir, no, it is as much as my place is worth to let him see me touch your money. Afterwards, if you like.”

As Sherlock Holmes replaced the half-crown which he had drawn from his pocket, a fierce-looking elderly man strode out from the gate with a hunting-crop swinging in his hand.

“What’s this, Dawson!” he cried. “No gossiping! Go about your business! And you, what the devil do you want here?”

“Ten minutes’ talk with you, my good sir,” said Holmes in the sweetest of voices.

“I’ve no time to talk to every gadabout. We want no strangers here. Be off, or you may find a dog at your heels.”

Holmes leaned forward and whispered something in the trainer’s ear. He started violently and flushed to the temples.

“It’s a lie!” he shouted. “An infernal lie!”

“Very good. Shall we argue about it here in public or talk it over in your parlour?”

“Oh, come in if you wish to.”

Holmes smiled. “I shall not keep you more than a few minutes, Watson,” said he. “Now, Mr. Brown, I am quite at your disposal.”
