Taking a timely look at the work of undercover policemen, Trust No One is a relentlessly exciting debut crime novel.

Marie Donovan is sent undercover into Manchester's underworld with the sole aim of bringing down crime lord, Jeff Kerridge.

It's a dangerous job, which becomes more perilous when her informant and clandestine lover, Jake Morton, is killed before he can give evidence.

When her role is exposed, it's not just a race against time for Donovan; it's all she can do to stay alive. With double dealings and unanswered questions, she can't even rely on her side to properly fight her corner.

Trust No One is a perfect read for fans of high-octane thrillers in the mould of Simon Kernick.
