"I can't think. I supposed of course you must have seen him. It was only a little while ago, not more than an hour. Have you been here all that time?"

"Yes, I've been here for the last two hours. What part of your grounds was it? Would you like to have me go over there and look around?"

"No, thank you. You are very kind, but I am sure it won't be necessary. He has gone by now, of course."

"I should be glad to try." Then, noticing her glance at his limp, he added: "Oh, I can navigate after a fashion, well enough for a short cruise like that. But it is funny that, if there was a tramp there such a little while ago, I didn't run afoul of him. Why, I was over there myself."

"You were?"

"Yes, you see, I——"

He stopped short. He had been about to tell of his short walk and how he had inadvertently trespassed within the Fair Harbor boundaries. But before he could speak the words a sudden and amazing thought flashed upon him.

"Eh?" he cried. "Why—why, I wonder——"

His visitor was leaning forward. Judging by her expression, she, too, was experiencing a similar sensation of startled surmise.

"Why——" repeated the captain.
