We sauntered down the street and looked quickly at the house. A brass sign on the wall beside the door read, "Mme. Margot's Beauty Shop."

"I see," commented Kennedy. "You know women of the type who frequent the Futurist and the Montmartre are always running to the hairdressing and manicure parlours. They make themselves 'beautiful' under the expert care of the various specialists and beauty doctors. Then, too, they keep in touch that way with what is going on in the demi-monde. That is their club, so to speak. It is part of the beauty shop's trade to impart such information—at least of a beauty shop in this neighbourhood."

I regarded the place curiously.

"Come, Walter, don't stare," nudged Kennedy. "Let's take a turn down to the Prince Henry and wait. We can get a bite to eat, too."

I had hardly expected that the pickpocket would play fair, but evidently the lure of the remaining twenty dollars was too strong. We had scarcely finished our dinner when he came in.

"Here it is," he whispered. "The house man here at the Prince Henry knows me. Slip me the twenty."

Kennedy leisurely tore the wrappings from the packet.

"I suppose you have already looked at this first and found that it isn't worth anything to you compared to twenty dollars. Anyhow, you kept your word. Hello—what is it?"

He had disclosed several small packets. Inside each, sealed, was a peculiar glistening whitish powder.

"H'm," mused Kennedy, "another job for the chemist. Here's the bankroll."
