When two young boys find a woman's body in a quarry, Jill Kennedy and DCI Max Trentham experience a definite feeling of deja vu. Five years earlier, four women were found murdered in exactly the same way. Weirdly, the bodies had each been discovered wrapped in a shroud - so the killer was soon dubbed 'The Undertaker'. Following Jill's profiling the police tried to arrest a loner called Edward Marshall, but the man had fled and, after a high-speed car chase, lost control and went over a cliff. His car was found but his body never was. Now there are three possibilities: Marshall somehow survived that plunge into the sea; Marshall was innocent and the real killer is back - or a copycat is at work. It is up to Jill and Max to work out whether a terrible mistake was made by the police five years ago...or whether the original murderer had an apprentice waiting in the wings.
