She emerged into the corridor at the same time as the maid was also coming out from the next door. The latter looked towards Katherine, over her shoulder, and an expression of intense surprise showed itself on her face. Katherine turned also, but by that time whoever it was who had aroused the maid’s interest had retreated into his or her compartment, and the corridor was empty. Katherine walked down it to regain her own place, which was in the next coach. As she passed the end compartment the door opened and a woman’s face looked out for a moment and then pulled the door to sharply. It was a face not easily forgotten, as Katherine was to know when she saw it again. A beautiful face, oval and dark, very heavily made up in a bizarre fashion. Katherine had a feeling that she had seen it before somewhere.

She regained her own compartment without other adventure and sat for some time thinking of the confidence which had just been made to her. She wondered idly who the woman in the mink coat might be, wondered also how the end of her story would turn out.
