Forrest accompanied us. I had promised to find him some lunch if he would do so, and to drive him back afterwards, and he was glad of the opportunity of obtaining from us such particulars as we could furnish him with concerning the person of whom he was in search. "Unless you want to send a message from Regent Street to the City," I remarked; "in which case one would save time by employing a sloth as messenger." The inspector waved aside the objection as frivolous. He occupied an easy chair opposite me; he was smoking one of my best cigars with every sign of active enjoyment; he sipped his glass of claret—he rarely touched anything stronger, he informed me—with the air of a connoisseur. "We shall beat him with the telegraph," said he. "Clearly he has one retreat where he can put up his car in safety. Probably he has more than one. It is not impossible for him to have several.

I suppose there is no one residing near whom you would consider a likely object of suspicion?" There flashed across my mind the strange similarity between Mannering's voice and the Motor Pirate's. But the notion was so absurd I was ashamed to mention it. I assured the inspector I knew of no one. "At all events, my
