Aspiring actress Elizabeth Smart lands her centre-stage role: her mutilated body is found dumped in North London's red light district. Clasped in her hand is a piece of human hair belonging to an unidentified body of a woman murdered two weeks ago.
PC Donal lands himself a place on the murder squad just as his unconventional brother, journalist Finton, unearths the secret double life of Elizabeth. The bodies mount, each clinging to the strands of hair belonging to the previous victim. The police are convinced it's the act of a serial killer. But how does Donal convince them it's not?
The only people he can trust are the victims he dances with in his dreams.
