When Rodney Hill, wrongly arrested for a series of murders, hangs himself, Jill Kennedy, the forensic psychologist whose profile led to Hill's arrest gives up her work with the police and moves to the peaceful village of Kelton Bridge to write self-help books, enjoy a quiet life with her cats and perhaps an occasional flutter on the horses. Someone is intent on reminding Jill that she made a mistake in the Rodney Hill case. Is it a malicious joke, or is there a more deadly agenda? Shirley Wells introduces forensic psychologist Jill Kennedy and DCI Max Trentham.
