“There is some mistake. You are wrong, sir. What is your name? Mr. Superintendent—my name is Siegel.”

“I dare say it is. Then why did you call yourself Witt?”

“I do not know what you mean.”

“I don’t forget faces. I should know you anywhere. You’re the Mr. Witt who prosecuted Dr. Horace Wilton. Come, come, the game’s up now.”

“What do you mean by that, sir?”

“Time to tell the truth,” said Reggie sweetly, “time you began to think of yourself, isn’t it? We know all about the evidence in the Wilton burglary. Why did you do it, Mr. Witt? It wasn’t safe, you know.”

“What do you want?”

“Well, where’s your friend Mr. Kuyper? We had better have him in.”

“Mr. Kuyper has gone out, sir.”

Reggie laughed. “Oh, I don’t think so. You’re not doing yourself justice. I don’t suppose you wanted to trap Dr. Wilton. You’d better consider your position. What is Mr. Kuyper’s little game with you?”
