“Certainly, there is a boy who seems to have some secret errand.”

“And what the errand is even a county constable could guess. But not one word shall they have from me, and I bind you to secrecy also, Dr. Watson. Not a word! You understand!”

“Just as you wish.”

“They have treated me shamefully - shamefully. When the facts come out in Frankland v. Regina I venture to think that a thrill of indignation will run through the country. Nothing would induce me to help the police in any way. For all they cared it might have been me, instead of my effigy, which these rascals burned at the stake. Surely you are not going! You will help me to empty the decanter in honour of this great occasion!”

But I resisted all his solicitations and succeeded in dissuading him from his announced intention of walking home with me. I kept the road as long as his eye was on me, and then I struck off across the moor and made for the stony hill over which the boy had disappeared. Everything was working in my favour, and I swore that it should not be through lack of energy or perseverance that I should miss the chance which fortune had thrown in my way.

The sun was already sinking when I reached the summit of the hill, and the long slopes beneath me were all golden-green on one side and gray shadow on the other. A haze lay low upon the farthest sky-line, out of which jutted the fantastic shapes of Belliver and Vixen Tor. Over the wide expanse there was no sound and no movement. One great gray bird, a gull or curlew, soared aloft in the blue heaven. He and I seemed to be the only living things between the huge arch of the sky and the desert beneath it. The barren scene, the sense of loneliness, and the mystery and urgency of my task all struck a chill into my heart. The boy was nowhere to be seen. But down beneath me in a cleft of the hills there was a circle of the old stone huts, and in the middle of them there was one which retained sufficient roof to act as a screen against the weather. My heart leaped within me as I saw it. This must be the burrow where the stranger lurked. At last my foot was on the threshold of his hiding place - his secret was within my grasp.

As I approached the hut, walking as warily as Stapleton would do when with poised net he drew near the settled butterfly, I satisfied myself that the place had indeed been used as a habitation. A vague pathway among the boulders led to the dilapidated opening which served as a door. All was silent within. The unknown might be lurking there, or he might be prowling on the moor. My nerves tingled with the sense of adventure. Throwing aside my cigarette, I closed my hand upon the butt of my revolver and, walking swiftly up to the door, I looked in. The place was empty.

But there were ample signs that I had not come upon a false scent. This was certainly where the man lived. Some blankets rolled in a waterproof lay upon that very stone slab upon which neolithic man had once slumbered. The ashes of a fire were heaped in a rude grate. Beside it lay some cooking utensils and a bucket half-full of water. A litter of empty tins showed that the place had been occupied for some time, and I saw, as my eyes became accustomed to the checkered light, a pannikin and a half-full bottle of spirits standing in the corner. In the middle of the hut a flat stone served the purpose of a table, and upon this stood a small cloth bundle - the same, no doubt, which I had seen through the telescope upon the shoulder of the boy. It contained a loaf of bread, a tinned tongue, and two tins of preserved peaches. As I set it down again, after having examined it, my heart leaped to see that beneath it there lay a sheet of paper with writing upon it. I raised it, and this was what I read, roughly scrawled in pencil: “Dr. Watson has gone to Coombe Tracey.”
