“I’ve always heard that you people at Scotland Yard have lists of all secret societies and things like that that are formed in London.”

“We try to keep up to date,” said Superintendent Battle cautiously.

“I suppose a great many of them aren’t really dangerous.”

“We’ve got a very good rule to go by,” said Battle. “The more they talk, the less they’ll do. You’d be surprised how well that works out.”

“And I’ve heard that very often you let them go on?”

Battle nodded.
