"Hard to put down, impossible to forget... subtle and disturbing" Today Lucy Ashdown is a girl with a mission - to find the driver who ran down and killed her sister Christine. Now she has a lead and she's off to London. Disgraced Detective Joe Lucas is as dedicated as Lucy. His aim is to bring her home. By any means necessary. Stepping into her sister's shoes, this small-town girl is thrust into a terrifying night journey of deceit, danger, and degradation. By recreating her sister's life, she unwittingly heads toward her sister's fate; and even as she believes that she's closing in on the murderer, the murderer is closing in on her. "A strange, powerful story of love and vengeance" Felicia Lamb, Mail on Sunday "Gallagher's descriptions pin down London's underbelly with deadly accuracy" The Times "Since Valley of Lights he has been refining his own brand of psycho-thriller, with a discomforting knack of charting mental disintegration and a razor-sharp sense of place" Daily Telegraph "This is the sort of tension that one could savour for more than 244 pages... a tense, nerve-racking tale... I'd be surprised if a better London novel hits the bookshops this year" Anne Billson, Time Out "Unquestionably Gallagher's finest novel yet" Vector Also available as an Ebook
