Sunday Times

«Hannah takes domestic scenarios, adds disquieting touches and turns up the suspense until you're checking under the bed for murders . . . it's this real-life research that helps make it so convincing - and so unsettling»

«Sophie Hannah has quickly established herself as a doyenne of the 'home horror' school of psychological tension, taking domestic situations and wringing from them dark, gothic thrills . . .
