"That's it, exactly," he said. "Think of the poor wretch's excitement when he saw your flag!"

Still, on looking back, it seems curious that we overlooked the way the red-headed man had followed Hutchins about. True, men are polygamous animals, Tish says, and are quite capable of following one woman about while they are sincerely in love with somebody else. But, when you think of it, the detective had apparently followed Hutchins from the start, and had gone into the wilderness to be near her, with only a suitcase and a mackintosh coat; which looked like a mad infatuation.

[Tish says she thought of this at the time, and that; from what she had seen of the P.T.S., Hutchins was much prettier. But she says she decided that men often love one quality in one girl and another in another; that he probably loved Hutchins's beauty and the amiability of the P.T.S. Also, she says, she reflected that the polygamy of the Far East is probably due to this tendency in the male more than to a preponderance of women.] Tish called me aside while Mr. McDonald was gathering firewood. "I'm a fool and a guilty woman, Lizzie," she said. "Because of an unjust suspicion I have possibly wrecked this poor boy's life."

I tried to soothe her. "They might have been wretchedly unhappy together, Tish," I said; "and, anyhow, I doubt whether he is able to support a wife. There's nothing much in keeping a livery stable nowadays."

"There's only one thing that still puzzles me," Tish observed: "granting that the grocery order was a grocery order, what about the note?"

We might have followed this line of thought, and saved what occurred later, but that a new idea suddenly struck Tish. She is curious in that way; her mind works very rapidly at times, and because I cannot take her mental hurdles, so to speak, she is often impatient.

"Lizzie," she said suddenly, "did you notice that when the anchor was lifted, we drifted directly to this island? Don't stare at me like that. Use your wits."

When I failed instantly to understand, however, she turned abruptly and left me, disappearing in the shadows.

For the next hour nothing happened. Tish was not in sight and Aggie slept by the fire. Hutchins sat with her chin cupped in her hands, and Mr. McDonald gathered driftwood.

Hutchins only spoke once. "I'm awfully sorry about the canoe, Miss Lizzie," she said; "it was silly and--and selfish. I don't always act like a bad child. The truth is, I'm rather upset and nervous. I hate to be thwarted--I'm sorry I can't explain any further."
