Four little words can ruin a life. When Jess meets five-year-old Daisy and her mum, Morag, in a local London park, they seem a perfectly happy and loving pair. Until Daisy whispers four little words that send ice seeping down Jess’s spine… She’s not my mum. Determined to save Daisy, Jess becomes obsessed with unearthing Morag’s secrets. As she digs ever deeper, her friends and family start to question her own increasingly paranoid behaviour… Four little words can end a life. But Jess knows what she heard and she’s certain the fear in Daisy’s eyes was real. Of course she isn’t imagining things… Or is she?
