Mary Shields is a moody, acerbic probation offer, dealing with some of Glasgow's worst cases, and her job is on the line. Liam Macdowall was imprisoned for murdering his wife, and he's published a series of letters to the dead woman, in a book that makes him an unlikely hero - and a poster boy for Men's Rights activists. Liam is released on licence into Mary's care, but things are far from simple. Shortlisted for Theakston Old Peculier Crime Novel of the Year Prize 2020.
