“Superintendent Battle has something up his sleeve,” said Anthony thoughtfully. “And it seems the essence of his plan that nobody should leave.”

“But, excuse me, Mr. Cade, you have been away.”

“With a string tied to my leg. I’ve no doubt that I was shadowed the whole time. I shouldn’t have been given a chance of disposing of the revolver or anything of that kind.”

“Ah, the revolver,” said Isaacstein thoughtfully. “That has not yet been found, I think?”

“Not yet.”

“Possibly thrown into the lake in passing.”

“Very possibly.”

“Where is Superintendent Battle? I have not seen him this afternoon.”
