Where Petals Fall by Shirley Wells

Five years ago, forensic psychologist Jill Kennedy and DCI Max Trentham thought they had seen the last of a serial killer the authorities had named "The Undertaker" when the suspect, Edward Marshall, plunged over a cliff during a chase. His body was never found. Now a local florist, Carol Blakely, has been murdered in a style very similar to "The Undertaker's." Is Marshall still alive or has a copycat surfaced? Both Jill and Max doubt their abilities, at times, because of past events. Will they be able to focus and capture the killer? Where Petals Fall is the third book in the Kennedy/Trentham series. It would appeal to people who like traditional British police procedurals.
