The taxi containing Manners and Cherriton drew to a halt before the door of No. 65. Cherriton paid the driver and dismissed him. The two men crossed the pavement, and Manners lifted the bright brass knocker. Three times Manners knocked.

He was that day attired with particular smartness in a grey, soft felt hat, a grey frock-coat, and light fawn linen gaiters. The Baron was wearing a navy-blue suit, made for him at the Army and Navy Stores. He also wore a grey felt hat, set well back on his head. In his hip pocket he carried a Mauser pistol, but this was always part of his apparel, as it were. Manners carried other little aids to his personal safety. But upon that evening their mission was pacific. They had only a desire to ask a certain lady if she had news of Treves.

Three times Manners applied the knocker; then footsteps came rapidly along the passage. The door was opened by a tall, brown-haired girl, wearing a white blouse and blue skirt, both of which Cherriton noticed were well cut. The girl's complexion was not pale, yet tended towards pallor. Her cheeks were softly rounded, her chin small, yet firm. Her eyes were grey, frank and steady in gaze. Cherriton, noticing her long, curved lashes and finely-arched brows, conceded that here, for once, he was looking upon a truly beautiful English woman.

"Good evening," Manners was saying. He had lifted his hat with extreme politeness.

"Good evening," responded the girl, looking with puzzled eyes from one man to the other.

"You have no doubt forgotten me," Manners spoke again, and then a faint recognition came to the girl's eyes.

"Oh, not at all," she said. "Will you come in?" She led the way to a little parlour, a bright little apartment, where she lived alone. She had made it as pretty and comfortable as possible with her small means.

The two Germans entered the room, and Manners closed the door. After some preliminary conversation he broached the subject of his visit, but artfully and cunningly hiding it in a veil of words.

"I have some business, madam," he said, "with"—he paused a moment—"with Mr. Treves. I have lost his address; I wonder if you could give it me?"

The girl looked at him a moment; an expression of reserve came into her face.
