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.
