The prequel to Sleepyhead. 1966 – Detective Sergeant Tom Thorne is a haunted man. Haunted by the moment he ignored his instinct about a suspect, by the horrific crime that followed and by the memories that come day and night, sunshine and shadow. So when seven-year-old Kieron Coyne goes missing while playing in the woods with his friends, Thorne vows he will not make the same mistake again. The solitary witness. The strange neighbour. The friendly teacher – all are in Thorne’s sights.  This case will make him – or break him.
