A gripping British lesbian murder mystery that asks what price we are prepared to pay to find out the truth. Outcast Ashley Spencer is in her second career as a rookie police constable in Cambridgeshire when she is rammed off the road one terrifying night. Forced to rescue her is undercover detective Darren "Mac" Mackenna, who claims to be a passing carpenter. A lifelong loner, Mac is leery of all relationships, and has been preoccupied with finding out how a close friend and colleague died. Impressed and grateful, Ashley uses her skills to track down her anonymous hero. An unlikely friendship forms between the opposite women. Still, Mac is suspicious: Can Ashley be trusted, or is she really part of a corrupt network of cops Mac is trying to expose? Should she trust her head or her heart to find the truth?
