The Honourable Richard Rollison (aka 'The Toff') received what he thought to be a letter, addressed simply to 'The Toff, London W1.' Remarkable in itself in reaching him, inside the envelope there was nothing more than a photograph of a beautiful, but unidentified, woman. In fact, the previous evening the woman herself had attended a society ball, looking somewhat pale but dressed immaculately in black satin and mink. No one knew who she was and she said she had lost her memory. Then, within days, the mystery deepened and The Toff was pitched against her cunning, with murder as the backdrop, whilst his own heart and feelings were both getting in the way of a solution and putting more lives in danger.
