Dr Olivia Winter II

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.

Within the pages of the notebook is a chart written in a code, which DI Linus Sutton believes holds the locations 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.

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?
