"Then we must lose no time in going to the woman," said the duke.
As he spoke, the cab which had been signalled by the detective drove up, and the cabman jumped down and opened the door.
The duke entered it and sat down on the back cushions.
His grace's servant, Kerr, came up to the window for orders.
"Take my luggage home to Elmthorpe House. Give my respects to Lady Belgrade, and say that I will join her ladyship this afternoon," said the duke.
The servant touched his hat and withdrew.
"To Number ——, Westminster Road," ordered Mr. Setter, as he mounted to the box-seat beside the cabman.
The latter started his horses at a good rate of speed, so that a drive of about forty minutes brought them to their destination.
The detective jumped down and opened the door, saying,
"Excuse me, your grace; but, I think, perhaps I ought to go in first to ensure you an interview with the woman?"
