"Look here, Amberley!" he said abruptly, "I wish you would give me a hand over this case."
"I know you do," replied Mr. Amberley, still smiling. "Frank, behave yourself," said his uncle.
"Oh, I know his little way, Matthews!" said the colonel.
"I've worked with him before. Now, own up, Amberley, you want to have a finger in this pie!"
"All right," said Frank. "But it's in."
"I thought as much. Now you know we can't have outsiders interfering, my dear fellow. No need for me to tell you that."
"Not a bit. I won't interfere."
"No, no, you misunderstand me! That wasn't what I meant."
"I know exactly what you meant, Colonel. You want me to act for the police. Very, very irregular."
"Possibly! Possibly! But you have worked with us before, after all. This case ought to interest you. It's one of the most incomprehensible I have ever struck."
