“We are out every night somewhere,” the girl said. “And madame will never allow us to pay a farthing. She must be very rich, for she’s ordered eight new frocks from Lucille’s.”

“She has no friends in London, has she?” Falconer asked casually.

“She didn’t have any when she arrived, but, of course, she now knows one or two people to whom we’ve introduced her.”

On the following day another curious telegram came through the wireless station at Witham. Dispatched from Marseilles, it had been sent across by wireless from Paris, and was addressed to Mildmay. It was in plain language, and read: “Urgent that Marguerite should come over. The change would do her good.—Jules.”

This puzzled Geoffrey more than ever. Why was madame wanted urgently at Marseilles, and what hidden meaning was contained in the declaration that the change would do her good? He was very anxious to ascertain if she ever met the mysterious Mildmay, and for that purpose he went to London one evening and again saw his friend the liftman.

No lady had visited Mr. Mildmay to his knowledge. She certainly might have called when he was off duty.

Hence Falconer determined to watch again, and after the lapse of several weary evenings, he one night followed Mildmay to the Savoy, where, just before supper-time, he took a seat in the lounge and idly lit a cigarette.

Ten minutes later Geoffrey saw standing at the head of the short flight of stairs the familiar figure of Madame Claudet, wearing a gorgeous theatre wrap. Her quick eye recognised Mildmay; therefore she went to take off her wrap, and a few moments later joined him.

From a distance Falconer watched them closely. Mildmay’s greeting appeared the reverse of cordial, for on his face was an angry, morose expression. After a brief conversation, they passed into the supper-room, where, in order to escape recognition, Geoffrey was forced to leave them. But he had established the fact of their secret friendship.

Next evening when he went to Upper Brook Street he found Sylvia alone, her mother having gone to the theatre with madame.
