"Yes, sir," he said, but I could see that he was astonished at my request.

Half an hour later he returned.

"Please, sir," he said, "they went along the St. Eia footpath, and then turned off as if they meant to go to Chy-an-Wheal."

Of course there was nothing suspicious in this, and yet my mind was not at ease. I had never been a man given to morbid fancies, and had always been too much a materialist to pay attention to people who profess to believe in premonitions; and yet my meeting with this man and woman had again stirred a thousand fancies in my mind, while the little creature sleeping on the rug seemed in some way to cause vague fears to come into my mind. Perhaps this was because of the state of my health. It seemed to me that my life, humdrum and commonplace though it might appear, was surrounded by mystery. I had vague intuitions which had no basis of reason.

After a time I rose and went out. I wanted to shake off the feelings which possessed me. A few minutes later I was scrambling down the cliff-side, hidden by the thick scrub of bushes. Presently I had a view of the whole of the little bay, which seemed absolutely deserted. I was far from fit to undertake what I had planned to do, but I could not resist the impulse which possessed me. I descended farther, and soon I was at the foot of the cliffs, looking eagerly around me. I found my way into the cave, but there was nothing suspicious there. Evidently no one had visited it since the last high tide. The sandy floor was untrodden; there were no marks of any one having been there. I crept out again, but still no one was visible.

"What a fool I am," I said to myself. "I am like a nervous child following a will-o'-the-wisp of my own fancies."

Still, what I had seen and heard could not be without meaning. I could have sworn to the fact that I had heard people at this very spot only a few hours before. I had heard a man say, "Is that the lot?" and some one had given him an indistinct reply. Of course this might have meant nothing, and yet I was sure it had. Again I examined the rocks inch by inch, but my search was altogether unrewarded. I passed the little fissure which led to the cave again, and this time I saw what I had never seen before. In an obscure corner, not far from the entrance, was another fissure. It was very narrow, but still wide enough for a man to squeeze his body through. I wondered why I had never seen it before, but on reexamining it I realized that it was so curiously formed, that any one with only a match to illuminate the cave could easily miss it. I squeezed myself through the fissure, and found myself in a cave far larger than the first.

In an instant the mystery of the last few months became plain to me. The new cave was as perfect a hiding-place as could possibly be found. Altogether there must have been some hundreds of cans of petrol placed there. This petrol was by different makers. Evidently it had been bought in comparatively small quantities at various places, and had been brought there to be ready for use as necessity arose.

I understood now the meaning of the words I had heard only a little while before.

"Is that the lot?"
