The body of a young woman is found on the streets of East London, in the shadow of the City's gleaming towers. No ID on her, just hard-earned cash. But there is no doubting the ferocity of the attack. DI Simon Fenchurch takes charge but, as his team tries to identify her and piece together her murder, they're faced with cruel indifference at every turn - nobody cares about yet another dead prostitute. To Fenchurch, however, she could just as easily be Chloe, his daughter still missing after ten years, whose memory still haunts his days and nights, his burning obsession having killed his marriage. When a second body is discovered, Fenchurch must peel back the grimy layers shrouding the London sex trade, confronting his own traumatic past while racing to undo a scheme larger, more complex and more evil than anything he could possibly have imagined.
