I've got you under my skin - Mary Higgins Clark

A Manhattan ER doctor is in the local playground with his young son when someone ruthlessly guns him down. Now his young widow, a television producer, is raising their son alone and is under pressure to come up with a successful TV series. Her new show will focus on cold case files. Revisiting unsolved crimes one at a time, she and her TV crew plan to gather friends and family of the victim who have lived under suspicion of guilt for many years. By paying them to reenact the crime on television, they will be given a chance to clear their name--unless, of course, they are guilty . . .
