A deadly collar bomb has been attached to her neck. To save her, DC Jake Tanner, on the first day of secondment from the Met, must answer a series of riddles and clues to defuse the device. The countdown to save her has begun... But as the investigation develops, two things become clear: this is The Crimsons' last height, and they're willing to do anything to ensure their survival; and two, not everyone is on Jake's side. A knot of corruption operating deep within the heart of Surrey Police is working against him every step of the way. Without knowing who to trust, Jake must decide whether to toe the line of duty or turn against his colleagues and solve the case that could cost him his life... Toe The Line is a gritty crime thriller perfect for fans of Simon McCleave, Rachel Mclean, and the BBC's Line of Duty.
