“Are you certain, Rudolph,” one of the men was saying, “that this new chauffeur of yours is the man for the job?”

“Have I ever made a mistake in summing up a man?” I heard Rayne answer. “I always trust my judgment when choosing a new hand.”

Where, before, had I heard the first speaker’s voice? I knew that voice quite well, yet, try as I would, I could not for the life of me place it.

“Yes,” the first speaker replied; “but, remember, in this case we are running an enormous risk. If the least hitch should occur——”

They lowered their voices until their talk became inaudible, and presently I heard one of them go out of the room. After waiting a minute longer I left the room and went along the short passage, which I now knew must lead to the room where I had heard them talking.

Rayne was alone, standing on the hearthrug with his back to the big, open firegrate.

“Did you send for me, sir?” I inquired.

“I did, Hargreave,” he replied in a friendly tone. “I sent for you because I want you to go to Paris to-night. You will take with you the suit-case you still have in your possession, and as you will go by a trading steamer from Newcastle, the voyage will take you some days. The suit-case contains valuable documents, so you must on no account let it out of your sight, even for a minute, from the time you leave here until you hand it over personally to the gentleman I am sending you to—Monsieur Duperré. He is staying at the Hôtel Ombrone, that very smart and exclusive place in the Rue de Rivoli. He will give you a receipt, which you will bring back to me here at once, coming then by the ordinary route. You won’t go by train to-day to Newcastle; you will drive yourself there in the Fiat. Paul will go with you and drive the car back.”

He went on to give me one or two minor instructions, and then ended: “That’s all, Hargreave.”
