When the body of a young girl is found dumped on the banks of the Thames, even the police are shocked by the brutality of her murder: horifically mutilated, severed in half and drained of blood, her death is a mirror image of an infamous 1940s case in Los Angeles known as ‘The Black Dahlia’.
That case was never solved, but now Detective Inspector Anna Travis must race against time to catch this ‘copycat killer’, dubbed ‘The Red Dahlia’ from the flower his victim wore in her hair. But there are no suspects and a media frenzy is spiralling out of control. Anna turns to her mentor, the brilliant and volatile Detective Chief Inspector James Langton, but the frictions of their romantic relationship are complicating the case.
And then a second girl is found, her death again mirroring the ‘Black Dahlia’, and as Anna and Langton close in on the prime suspect they uncover a shocking web of sadistic sexual evil and a family’s murderous secrets.
