'Once again, Michael Wood, the master of horror and suspense, has written a book that put me through the wringer with its taut, horrifying, dark and devious storyline.’ ⭐⭐⭐⭐⭐

From the dark mind behind the DCI Matilda Darke series, comes the next novel in a gripping new series.

Dr Olivia Winter is back. And she’s got a brand new case to solve.

A BRUTAL MURDER

When Isaac McFadden is found with the dismembered body of a young man in the boot of his car, it’s an easy conviction for the jury. But, then a notebook is discovered in Isaac’s house, and the police believe they have a serial killer on their hands.

A CRYPTIC CODE

Within the pages of the notebook is a chart written in a code, which DI Linus Sutton believes holds the location of more bodies. Made up of seemingly random words, numbers and symbols, and with a suspect who is refusing to talk, Sutton enlists the help of Forensic Psychologist Dr Olivia Winter.

THE FINAL GIRL

Having previously survived attacks from two killers, Olivia is the real life ‘final girl’. But can she unlock the code before her luck runs out?
