"Anything gone this time?" asked Tom Witherbee.

"Clothes!" exploded Mr. Davidson. "My room ransacked, Billy's room turned topsyturvy, bureau drawers dumped out on the floor and all that sort of thing."

"But when?"

"Since we came up here, of course! I had to send the boat back for my grips. I'm going away to-night and I forgot 'em. And then they saw what happened. A fine mess! I'd like to know what good it did to organize. He slipped right in under their noses and slipped out again."

"And no clue?"

"Clue—"

Mr. Davidson checked the word that was intended to follow immediately thereafter and glared at the Jones boy, who was the questioner.

"Clue!" he said, beginning afresh. "I've quit looking for clues. I'm looking for results. And I can get bunches of one and none of the other. And here I am, headed for Denver to-night, and nobody but a pack of fool servants to look after the place. I suppose the island'll be gone when I get back."

"It's appalling," said Marjorie Winter.

"You're right, ma'am," declared Mr. Davidson truculently. "It's worse than appalling. It's hell! Excuse me. But that's what it is."
