'Scotland Yard would give a good deal to know this address, my dear fellow.'

'They shan't have it,' cried Lord Arthur, laughing; and after shaking the young Russian warmly by the hand he ran downstairs, examined the paper, and told the coachman to drive to Soho Square.

There he dismissed him, and strolled down Greek Street, till he came to a place called Bayle's Court. He passed under the archway, and found himself in a curious cul-de-sac, that was apparently occupied by a French Laundry, as a perfect network of clothes-lines was stretched across from house to house, and there was a flutter of white linen in the morning air. He walked to the end, and knocked at a little green house. After some delay, during which every window in the court became a blurred mass of peering faces, the door was opened by a rather rough-looking foreigner, who asked him in very bad English what his business was. Lord Arthur handed him the paper Count Rouvaloff had given him. When the man saw it he bowed, and invited Lord Arthur into a very shabby front parlour on the ground-floor, and in a few moments Herr Winckelkopf, as he was called in England, bustled into the room, with a very wine-stained napkin round his neck, and a fork in his left hand.
