"Well, put it into execution at once," returned his superior.

Manners looked at his watch.

"That way won't do until after six o'clock. After six o'clock, Herr Baron, I will take you into the presence of the most beautiful girl in England."

"I do not admire English beauty," answered Rathenau, caustically.

Manners lifted his hands.

"Ah, but this one, she is wonderful!"

"How will she know about Treves, any more than we do?"

Manners looked across at him.

"Leave that to me," he said, "I can assure you she will know." He took out his pocket-book and looked up an address. "If we go now," he said, "we shall get there a little after six, in time to interview the lady on her return from business."

Half an hour later a taxi sped along Kentish Town Road and turned into Bowles Avenue, Camden Town. The street was a particularly respectable one, with windows and doors freshly painted. Judging from the cleanliness of the curtains and the brightness of the door handles, the inhabitants of this thoroughfare each took a pride in his residence.
