A Mask for the Toff — John Creasey

The Honourable Richard Rollison (aka ‘The Toff') is called upon to solve the mystery of a young and terrified French girl who is found wandering in London's East End. Is she pretending, or really frightened? Part of the answer is supplied by a woman who is afraid for her life, and a man who knew the answer is murdered. With a trip to Paris ‘The Toff' solves the puzzle, but not as easily as might be imagined.
