All you will be left with is fear.

Without a single clue, the police struggle to find answers.

But when another missing person reappears, broken by months of solitary confinement, a deadly pattern becomes terrifyingly clear: a twisted predator is driving his victims to madness.

DC Corcoran, still haunted by a previous case, and Dr Marie Philips, a leading criminal psychiatrist, must work together to find a link between the survivors - and unravel the deadliest of puzzles. And when another woman disappears, every second will be critical.... 

With a gripping hook that grabs you from the very first second, this is chilling thriller is perfect for listeners of Chris Carter, M.J. Arlidge, Sharon Bolton and Fiona Cummins.
