“I don’t quite understand,” said Anthony.

“Why are we all being kept here in this way? The inquest was over yesterday. The Prince’s body will be removed to London where it is being given out that he died of heart failure. And still nobody is allowed to leave the house. Mr. Lomax knows no more than I do. He refers me to Superintendent Battle.”

“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.”
