I stood for some moments transfixed with surprise at seeing Tom Kinlay in this situation. He was lying with his head and shoulders upon a square box and snoring loudly. Behind him were piled up many kegs, which I doubted not were filled with contraband spirits. As I reasoned on all this I surmised that Tom was there probably by the directions of his father, whom, after what I had heard and seen, I could not but associate with the smugglers.

I now, for the first time, saw also some shade of reason for the enmity that had existed between Carver and my father. At the time of the wreck of the Undine, years before, when he was stranded in the cavern, Carver had no doubt seen the convenience of the place for smuggling purposes. The cave was commodious, and the fact that its situation was little known among the natives gave it the additional advantage of secrecy.

I could not tell whether Kinlay had carried on his illicit traffic whilst my father was alive, but I guessed that this was so; and believing that my father was the only man who knew his secret, I saw reason sufficient for enmity. My father's death had removed the one great obstacle in the way of Carver's carrying on the smuggling unsuspected. It had also enabled him to become a pilot--a position which gave unusual opportunity to a man so unscrupulous. As pilot he was able to board any vessel that entered the Orcadian waters, and in the case of ships which came over from the Continent or from the north of Scotland with contraband goods, a transfer of cargo could be boldly effected without exciting suspicion. And here in the cave I saw before me a part of the smuggler's store.

Having explored the cavern by the light of my lantern, I was forced to believe that Thora was not there. I returned once more to the kegs of spirits before departing.

Tom was still sound asleep. Approaching him, I turned the light upon him and knelt down, shielding the light from his closed eyes.

Suddenly I was alarmed by hearing the noise of voices at the outer part of the cave--the voices of many men. I blew out the light of my lantern, rose to my feet, and slipped into the shadow to watch, for I did not doubt that these were the smugglers.

I had not stood there very long before I observed a flickering of lights, and the sound of men's feet and voices came nearer and nearer. Then I saw the lights of two lanterns, and distinguished the figures of five men. Their sea jackets were powdered with snow.

"Now, lads," said a hoarse voice that I recognized as Carver Kinlay's, "look smart. Get as many as ye can into the boat, then roll the others into the water."

His eyes rested upon the sleeping form of his son.

"Hullo!" he cried, "why, here is the young devil after all!"
