"Sylvia had on the wrong stockings for her dress, and her lipstick was all crooked, so I think things are pretty grim."

Lovely, foolish Sylvia Colesborough knew him only as a voice on the telephone. It told her how she could earn the money she had lost at cards. She enlists her reluctant friend, debutante Gay Hardwicke, to help her earn this money, and safeguard her husband's reputation into the bargain. But blackmail turns to murder in this classic country house whodunit, and Gay's young man is soon suspect number one...

And Mr. Zero? Whether he loses or wins, his fate lies at the end of a story bearing the reader along through mystery, romance, intrigue and murder to a thrilling climax.

Mr. Zero was originally published in 1938. This new edition features an introduction by crime fiction historian Curtis Evans.
