e 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

For a minute I stood there with the paper in my hands thinking out the

he had set an agent--the boy, perhaps--upon my track, and this was his
report. Possibly I had taken no step since I had been upon the moor
which had not been observed and reported. Always there was this feeling
of an unseen force, a fine net drawn round us with infinite skill and
delicacy, holding us so lightly that it was only at some supreme moment
that one realized that one was indeed entangled in its meshes.

If there was one report there might be others, so I looked round the hut
in search of them. There was no trace, however, of anything of the kind,
nor could I discover any sign which might indicate the character or
intentions of the man who lived in this singular place, save that he
must be of Spartan habits and cared little for the comforts of life.
When I thought of the heavy rains and looked at the gaping roof I
understood how strong and immutable must be the purpose which had kept
him in that inhospitable abode. Was he our malignant enemy, or was he by
chance our guardian angel? I swore that I would not leave t
