"Whoever it is will get no good by it," said Miss Drewitt, who had had a pious upbringing.

"And if they've got the map they'll go after the island," said the captain, pursuing his train of thought.

"Perhaps they won't find it after all," said Prudence.

"Perhaps they won't," said the captain, gruffly.

He got up and paced the room restlessly. Prudence, watching him with much sympathy, had a sudden idea.

"Edward Tredgold was in here alone this afternoon," she said, significantly.

"No, no," said the captain, warmly. "Whoever has got it, it isn't Edward Tredgold. I expect the talk about it has leaked out and somebody has slipped in and taken it. I ought to have been more careful."

"He started when you said that you had burnt it," persisted Miss Drewitt, unwilling to give up a theory so much to her liking. "You mark my words if his father and Mr. Chalk and that Mr. Stobell don't go away for a holiday soon. Good-night."

She kissed him affectionately under the left eye—a place overlooked by his beard—and went upstairs again. The captain filled his pipe and, resuming his chair, sat in a brown study until the clock of the neighbouring church struck two.

It was about the same time that Mr. Chalk fell asleep, thoroughly worn out by the events of the evening and a conversation with Mr. Stobell and Mr. Tredgold, whom he had met on the way home waiting for him.
