“I couldn’t say, Chot; it’s too much of a problem for me. What were the noises in the night? Had Mr. Lawrence anything to do with them? What this and what that? One might go on asking questions forever, but finding the answers is another matter.”

“Well, he must have had urgent reasons for leaving at that time of night. No man wants to have his sleep disturbed to take a journey that can just as well be taken by daylight.”

“Then I suppose this was a journey that couldn’t be taken by daylight.”

They were still discussing the matter of their host’s disappearance, and the strange noises of the night, when they were startled by a yell from Bert, and turning their gaze in the direction of the lodge, saw him start up from the hammock and stand for an instant in a listening attitude. Then, looking over toward them, he beckoned to them in such a vigorous way that they knew he meant come at once. As they pushed their canoes into the water and jumped aboard, they saw him dash madly into the lodge.

Fleet, Pod and Hoki had heard the cry, and dropping their fishing tackle, they, too, rushed toward the lodge Pod leading by several lengths.

“Something wrong, sure,” said Chot, between clenched teeth. “A little faster, Tom; we may be needed.”

The other boys reached the lodge first and disappeared within just as Chot and Tom were pulling their canoes up on the island. When they had negotiated the slight rise and entered the building, there was no one to be seen.

Fleet came perspiring out of the basement a moment later, followed by Pod and Hoki. Their faces were white and they were shaking in every limb.

“What’s the matter?” Chot demanded, seizing Fleet’s arm and shaking him violently.

“It’s—it’s Bert,” was the reply.
