The nocturnal visitor was a young man, frail and thin, with a black moustache, which intensified the deadly pallor of his face. He could not have been much above twenty years of age. I have never seen any human being who appeared to be in such a pitiable fright, for his teeth were visibly chattering, and he was shaking in every limb. He was dressed like a gentleman, in Norfolk jacket and knickerbockers, with a cloth cap upon his head. We watched him staring round with frightened eyes. Then he laid the candle-end upon the table and disappeared from our view into one of the corners. He returned with a large book, one of the logbooks which formed a line upon the shelves. Leaning on the table, he rapidly turned over the leaves of this volume until he came to the entry which he sought. Then, with an angry gesture of his clenched hand, he closed the book, replaced it in the corner, and put out the light. He had hardly turned to leave the hut when Hopkin’s hand was on the fellow’s collar, and I heard his loud gasp of terror as he understood that he was taken. The candle was relit, and there was our wretched captive, shivering and cowering in the grasp of the detective. He sank down upon the sea-chest, and looked helplessly from one of us to the other.
