Three strangers. Three secrets. And one big lie. First there's Ursula. Unable to face up to the tragedy that consumes her, her world has shrunk to an almost unrecognisable state. But a string of missing people - and her housemate's permanently locked basement door - set off a chain of events that she soon has no control over. Then Alice, who's in the first flush of her relationship with Simon. A man she met by chance, and who seems perfectly normal - except that he flinches at the slightest touch. And Gareth, who lives a humdrum life as he struggles to cope with his mum's increasing dementia. She can't remember much about her days - not even when a postcard from his long-dead father comes through the door. None of these three strangers have ever met, but their worlds will soon collide in the most dramatic way possible, as the lie that has been told is finally answered for. The master of suspense is back! Prepare yourself for the latest nail-shredding, heart-in-mouth rollercoaster ride from the Sunday Times bestseller.
