A city in fear of the night
A detective at home in the dark

JAKE SAWYER is in demand. With his profile raised after successes in the Peak District, he’s called to London to help the Met with a baffling case which has shocked the nation.

A family of four has been tortured and murdered in their upscale Hammersmith home. The crime’s disturbing details are kept private to retain the victims’ dignity and to deter copycats.

As Sawyer struggles to settle in the big city and keep his mental health in balance, he follows a private theory about the killer which leads him deep into an urban underworld where secrets rule, and the lines between pleasure and pain are blurred.
