There's a serial killer targeting the streets of Newcastle, seemingly picking his victims at random but subjecting them all to the same torturous end. When the Chief Inspector on the case goes missing, it falls on DCI Ryan to track down the man who is brutally murdering women and goading the police to 'catch me if you can'. As everyone becomes a suspect, Ryan and his team get drawn further and further into the case, but for Ryan the nightmare gets closer to home than he could ever have imagined. 

After an elite criminal profiling unit is shut down amid a storm of scandal and mismanagement, only one person emerges unscathed.

Jack Warr is a young DC with the Metropolitan Police. Charming but aimless, Jack can't seem to find his place in the world - until he's drawn into an investigation that turns his life upside down. In the aftermath of a fire at a derelict cottage, a badly charred body is discovered, along with the burnt remnants of millions of stolen, untraceable bank notes - the hidden legacy of Dolly Rawlins and her gang of Widows. Jack's assignment to the case coincides with an investigation into his own past.

When a body is discovered, bled dry on a beach, the sleepy seaside town of Weston-super-Mare wakes up to a nightmare.
