By the New York Times bestselling author of Slow Horses The hunter becomes the hunted in the thrilling follow-up to Down Cemetery Road, now an Apple Original series. After narrowly escaping an attempt on her life, Oxford private investigator Zoë Boehm is determined to keep a low profile. So when Caroline Daniels takes a fatal fall in front of a train and her boyfriend fails to turn up at the funeral, Zoë turns down the case--despite the insistence of Caroline's boss, who is convinced it was foul play. Then, a local teen boy plunges from the top of a London tower block and dies in disturbingly similar circumstances, and Zoë has no option but to follow the evidence. With the help of her close friend Sarah Tucker, Zoë attempts to track down Caroline's boyfriend, who seems to have vanished without a trace. As her search uncovers dangerous threads, including police corruption and a potential serial killer at work, she begins to suspect she's being watched. Has the killer found her first--and if he has, will that make her the next victim?
