Five-part thriller by acclaimed screenwriter Anthony Horowitz. William Travers used to be a distinguished London barrister, but all that changed after he suffered a complete nervous breakdown, abandoned his career and uprooted his family to Suffolk. His wife Jane also gave up her glittering job in publishing and now works part-time in a young offenders institute. William's life is thrown off-balance again when he sees a figure from his past on a railway platform. At the same time, old university friend Martin Newall asks William to defend him against murder charges for a killing which he swears he did not commit. William returns to London and his old chambers, and finds past allegiances being tested and his family's fragile peace put under threat. Back in Suffolk, a body is discovered on a deserted farm and DI Mark Wenborn is assigned his biggest case yet.
