Berry skips between Claire's present-day investigations and her reconstruction of her parents' lives almost three decades earlier in this beautifully paced and satisfyingly ominous story. (Observer)

As well as confirming the promise of Berry's debut, Under the Harrow, the book demonstrates that fusing fiction and true crime can be mesmerisingly effective. (The Sunday Times)

Flynn Berry writes thrillingly about women raging against a world that protects cruel and careless men. She's less preoccupied by scenes of abuse than the psychological toll of its threat. Her protagonists seethe over their knowledge of violence and are fueled by a howling grief for its victims. Berry proved in Under the Harrow that her prose can be as blistering as it is lush. Here, too, the writing is rich and moody, without any unnecessary fuss... The ending is as shocking as it is satisfying. (New York Times, Editor's Choice)

[An] interesting ... reimagining of the Lord Lucan story... Berry brings the story to a satisfyingly shocking conclusion. (Guardian)
