He looked rather startled. "That's it exactly," he said, after a moment. "As well as I can make out there are about a hundred. If you think," he said fiercely, raising his voice, "that I'm going to back out and let somebody else in, I'm not. And that's flat."

"It's a life-and-death matter," said Tish.

"You bet it's a life-and-death matter."

"And--what about the--the red-headed man over there?"

His reply amazed us all. "He's harmless," he said. "I don't like him, naturally; but I admire the way he holds on. He's making the best of a bad business."

"Do you know why he's here?"

He looked uneasy for once.

"Well, I've got a theory," he replied; but, though his voice was calm, he changed color.

"Then perhaps you'll tell me what that signal means?"

Tish gave him the glasses and he saw the red flag. I have never seen a man look so unhappy.

"Holy cats!" he said, and almost dropped the glasses. "Why, he--he must be expecting somebody!"

"So I should imagine," Tish commented dryly. "He sent a letter by the boat to-day."

"The h--l he did!" And then: "That's ridiculous! You're mistaken. As a--as a matter of fact, I went over there the other night and commandeered his fountain pen."

So it had not fallen out of his pocket!

"I'll be frank, ladies," he said. "It's my object just now to keep that chap from writing letters. It doesn't matter why, but it's vital."

He was horribly cast down when we told him about Hutchins and the pen and ink.

"So that's it!" he said gloomily. "And the flag's a signal, of course. Ladies, you have done it out of the kindness of your hearts, I know; but I think you have wrecked my life."

He took a gloomy departure and left us all rather wrought up. Who were we, as Tish said, to imperil a fellow man? And another thing--if there was a reward on him, why should we give it to a red-haired detective, who was rude to harmless animals and ate canned corn for breakfast?

With her customary acumen Tish solved the difficulty that very evening.

"The simplest thing," she said, "of course, would be to go over during the night and take the flag away; but he may have more red handkerchiefs. Then, too, he seems to be a light sleeper, and it would be awkward to have him shoot at us."
