"I stand here for a taxi, but we have agreed to walk, is it not so?

A man was standing there, engaged in conversation with a plainly-dressed young woman.

To Norgate there was something vaguely familiar about the latter, who turned to glance at him as they strolled by on the other side of the road.

It was not until they reached the corner of the street, however, that he remembered.

She was the young woman at the telephone call office near Westbourne Grove!.
