'Crofts constructs his alibi with immense elaboration...The story is highly successful, and Mr Crofts is to be congratulated upon his experiment' - Dorothy L. Sayers

We begin with a body. Andrew Crowther, a wealthy retired manufacturer, is found dead in his seat on the 12.30 flight from Croydon to Paris. Rather less orthodox is the ensuing flashback in which we live with the killer at every stage, from the first thoughts of murder to the strains and stresses of living with its execution. Seen from the criminal's perspective, a mild-mannered Inspector by the name of French is simply another character who needs to be dealt with. This is an unconventional yet gripping story of intrigue, betrayal, obsession, justification and self-delusion. And will the killer get away with it?
