Jill Kennedy is a forensic psychologist who stopped working with the police after a particularly traumatic case. She's drawn into partnering with them again after Martin Hayden, a local teenager, goes missing. Jill's former live-in boyfriend, DCI Max Trentham, is heading up the investigation and his presence causes her feelings for him to resurface--both love and anger, since he cheated on her. Jill's expertise in reading people comes in handy, since Martin wasn't that likable and his family kept to themselves. Then another, particularly brutal crime takes place. Will Max and his team be able to piece all the clues together with Jill's help? A Darker Side is the second book in the Kennedy/Trentham series. I really liked it and look forward to reading the first. A British police procedural in the style of Cynthia Harrod-Eagles and Jo Bannister.
