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 grey 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 grey 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.
