The New York Times bestseller and Guardian Book of the Month 'This flawless masterpiece deserves to be a bestseller.' DAILY EXPRESS 'Tough, tense and twisty - but tender, human and deeply affecting, too ... I don't have a sister, but when I finished the book I called my brother, just to hear his voice.' LEE CHILD 'An outstanding crime novel.' PAULA HAWKINS, author of The Girl on the Train _____________________________________ KENSINGTON AVE, PHILADELPHIA: THE FIRST PLACE YOU GO FOR DRUGS OR SEX. THE LAST PLACE YOU WANT TO LOOK FOR YOUR SISTER. Mickey Fitzpatrick has been patrolling the 24th District for years. She knows most of the working women by name. She knows what desperation looks like and what people will do when they need a fix. She's become used to finding overdose victims: their numbers are growing every year. But every time she sees someone sprawled out, slumped over, cold to the touch, she has to pray it's not her sister, Kacey. When the bodies of murdered sex workers start turning up on the Ave, the Chief of Police is keen to bury the news. They're not the kind of victims that generate a whole lot of press anyway. But Mickey is obsessed, dangerously so, with finding the perpetrator - before Kacey becomes the next victim. _____________________________________ 'A remarkable, profoundly moving novel about the ties that bind and the irrevocable wounds of childhood. It's also a riveting mystery, perfectly paced. I loved every page of it.' DENNIS LEHANE 'Outstanding . . . an intense family thriller . . .
