In the summer of 1992, Jeremy Howe and his wife, Lizzie, were tending to last-minute holiday preparations. Lizzie was leaving to teach at a summer school before she could join Jeremy and their two daughters, Jessica, six and Lucy, four, at the seaside. That night, arriving at his mother’s in Suffolk, Jeremy managed to get the excited girls to go to sleep, irritated that their mother hadn't called to say goodnight as she had promised. Just after midnight the household was woken by a policeman who had come to tell them that Lizzie was dead. She had been murdered.
