Elderly Martha Beckett is a prisoner in her own home, and has been ever since her older brother disappeared at just nine years old. Six months on from her last brush with the paranormal, police officer Annie Graham, now Annie Ashworth, dreams of settling down and starting a family. But now that serial killer Henry Smith has escaped, she knows that trouble is coming. She thwarted him once, and he’s out for revenge.

There's not much that scares Annie Graham. Not even the horrors she has witnessed during her years on the police force. When she agrees to look after her brother's farmhouse, she finds herself drawn to the crumbling old mansion in the woods nearby. But an innocent exploration of the empty ruin and the discovery of the diary of former resident Alice leaves her more than a little spooked. She knows it holds the secrets to a dark past, and she has to find out more.

1692. On the outskirts of Salem, a bookstore stands covered in overgrown vines. Inside, a young woman hides a linen-wrapped journal under a loose floorboard and runs away, panicked by the sound of hounds barking in the distance. The bookstore vanishes into thin air…

When the body of a woman is found hanging from a tree in her front garden, rookie Detective Morgan Brookes is first on the scene. But Olivia Potter is past saving. And when her husband and daughters cannot be traced, Morgan knows there is more to this tragedy. And then she finds them. Lying huddled together in the dark basement, each of their faces covered with a small cotton cloth, their bodies cold to the touch. But as Morgan kneels beside the family, she realizes that one of the girls is still breathing.

Annie Ashworth is on maternity leave from her police job, enjoying spending time with baby Alfie.

But when she starts having strange dreams – dreams that turn out to be linked to a local murder – she can’t stop herself from digging. There’s an eerie connection to a serial killer from the 1950s, and Annie fears that the same dark forces are back.
