When body parts are found on the banks of the River Thames in Deptford, DI Angelica Henley is tasked with finding the killer. Eerie echoes of previous crimes lead Henley to question Peter Olivier, aka The Jigsaw Killer, who is currently serving a life sentence for a series of horrific murders. When a severed head is delivered to Henley's home, she realises that the copycat is taking a personal interest in her and that the victims have not been chosen at random. To catch the killer, Henley must confront her own demons - - and when Olivier escapes from prison, she finds herself up against not one serial killer, but two.

    The isolated house he buys sight unseen should give him the space to come to terms with his grief and the quiet to allow him to work. Kilnsgate House turns out to be rather more than he expected, however. A man died there, sixty years ago. His wife was convicted of murder. And something is pulling Chris deeper and deeper into the story of Grace Elizabeth Fox, who was hanged by the neck until she was dead...

    It was supposed to be the perfect summer getaway--until they met Severine, the girl next door. For Kate Channing, Severine was an unwelcome presence, her inscrutable beauty undermining the close-knit group's loyalties amid the already simmering tensions. And after a huge altercation on the last night of the holiday, Kate knew nothing would ever be the same. There are some things you can't forgive, and there are some people you can't forget, like Severine, who was never seen again. Now, a decade later, the case is reopened when Severine's body is found in the well behind the farmhouse. Questioned along with her friends, Kate stands to lose everything she's worked so hard to achieve as suspicion mounts around her. Desperate to resolve her own shifting memories and fearful she will be forever bound to the woman whose presence still haunts her, Kate finds herself buried under layers of deception with no one to set her free.
