Fleur Mason wakes in the house of Edwina Lovett and her son Tristan, well-meaning strangers who found her wandering in the rain at midnight, dressed in only her nightgown.
Fearing she is being hunted, Fleur pretends to have lost her memory. The kindly Lovetts care for her, even as she relives the traumatic events that brought her there; a marriage that ended in murder.
As Fleur struggles through hallucinations and fever, she slowly becomes aware that she isn't the only one in the house with something to hide.
