DCI Hanlon is going undercover.

Oxford Philosophy lecturer Dr Gideon Fuller is in the frame, but Hanlon is not convinced.


From the specialist brothels in Oxford and Soho, to the inner sanctum of a Russian people trafficker with a taste for hurting women, the trail leads Hanlon deeper and deeper into danger - until she herself becomes the killer's next target...


Can Hanlon track down the killer before it's too late?


A thrilling new case for DCI Hanlon. Perfect for fans of Angela Marsons, Lisa Regan and Mark Dawson.
