A young woman has been murdered, and a neighbour, a retired teacher from Chapleton College, is arrested. An eccentric loner – intellectual, shy, a fastidious dresser with expensive tastes – he is the perfect candidate for a media monstering. In custody he is interviewed by two detectives: the smart-talking, quick-witted Gary, and his watchful colleague, Ander. Ander is always watchful, but particularly now, because the man across the table is his former teacher – Michael Wolphram – whom he hasn’t seen in nearly 30 years.Another outsider, another loner in a school system rife with abuse and bullying, Ander has another case to solve: the cold case of his own childhood.
