"You'll make your arrest all right," promised Amberley. "I'm not sure you don't deserve promotion for this case. I wish I'd seen you getting into the motorboat."
"Yes, I've no doubt you do, sir. But p'r'aps instead of keeping on about me and the motorboat you'll tell me who I been chasing all this time?"
"But I thought you knew that," said Mr. Amberley, raising his brows.
"I got my doubts," confessed the sergeant. "When I said to you what I did say about that Baker - what I meant was…'
"Don't spoil it, Sergeant. You said he was my man." The sergeant said cautiously: "Suppose I did?"
"You were quite right," said Mr. Amberley. "He is my man."
The sergeant swallowed hard, but recovered immediately and said brazenly: "That's what I was saying if you hadn't gone and interrupted me. Spotted him at once, I did."
Mr. Amberley grinned. "Yes? Just as you spotted the real criminal?"
"Look here, sir!" said the sergeant. "If it ain't Baker there's only one other man it can be, so far as I can see, and that's Mr. Fountain."
"At last!" said Amberley. "Of course it was Fountain."
