All at once the night-breeze wafted to them the scent of a good cigar, and they knew that whoever it was must be smoking. At the same moment, Morton felt a tug at his line, and he knew a fish had hooked itself. It was all he could do to keep from dragging it in; but he was, in spite of his boasting, afraid of his nocturnal expedition coming to his father's ears, and he remained still. Fisherman Dick had moved so silently that Morton had not heard him; but all at once the planks overhead seemed veined with light, and the figure of the fisherman could be seen dimly, with his face close up to a hole in the planking. The light died out as quickly as it shone, and the odour of tobacco diffused itself again, while the man overhead began to walk slowly up and down. Tug-tug-tug! How that fish--a big one, too--did pull! But Morton resisted the temptation, and waited, till all at once it seemed to him that the smoker must have heard them, and was about to come down, for he was evidently listening. Then there was a shuffling of feet, a curious expiration of the breath, and a sort of grunt, followed by utter silence; and then, some fifty yards away, right in front of where Morton sat, there was a faint golden splash in the sea, and the noise of, as it were, a falling stone or piece of wood. Almost at the same moment Morton noticed that his line had become phosphorescent, and he could see it for some distance down as the fish he had hooked dragged it here and there. Then there was a sigh overhead as of relief, and the steps were heard again, gradually going back along the pier, and dying slowly away. Simultaneously, Morton Denville and the fisherman began hauling in their lines, the former listening the while, to make sure that the promenader did not return; and then, as all was silent, their captives were drawn on to the open planking, to break the silence with flapping and beating and tangling the lines. "What light was that, Dick?" said Morton, as he threw his fish into the basket. "Dunno, zackly. Some way o' lighting another cigar." "Who was it--could you see?" "How's it likely I could see, squintin' through a hole like that? Some 'un or 'nother stretching his legs, 'cause he ain't got no work to do, I s'pose." "But couldn't you see his face?" "See his face? Is it likely? Just you get up and look through that hole. Why, I had to look straight up, then sidewise, and then straight up again, and that bends your sight about so as you couldn't even do anything with a spyglass." "I believe you could see who it was, and won't tell me." "Hear that, now! Why shouldn't I want to tell? Says you, I'm out on the sly, and nobody mustn't know I'm here." "No, I didn't," said Morton shortly. "Well, lad, not in words you didn't; but that's how it seemed to be, so I kep' as quiet as I could, and whoever it was didn't hear us." "What did he throw into the water?"
