“Before you fired the signal shot?”

“Yes. I could hardly believe my eyes. He just seemed to disappear into thin air. Well, I didn’t lose any time firing the shot, I can tell you. I could see your boat away up the bay.”

“The wind was against us,” said Frank. “We tried to get here quickly, but we didn’t have any luck.”

“He’s still on the island,” said Joe quickly. “I’m pretty sure of that.”

“Wonder how he got here,” remarked Chet. “There isn’t any other ice-boat around, that we saw.”

“Probably walked over from the mainland,” Frank remarked. “Well, I guess we had better explore a bit and see if we can’t get a sight of him. You’re sure you didn’t recognize him, Joe?”

“No. I couldn’t say if the man was Hanleigh or not. I didn’t get a good look at him at all.”

“We’ll get a good look at him,” growled Biff. “And mighty soon, too.”

“I suggest that two of us take the north side of the island and the other two take the south,” said Joe.

Frank shook his head.
