A naive young woman from Ulster finds herself trapped in the volatile, manipulative orbit of her wealthy employers during a trip to London. Eileen Hughes, possessing a haunting beauty and a sheltered upbringing, accepts an invitation to holiday with Bernard and Mona McAuley, unaware of the fractured state of their marriage. As the McAuleys draw her into their private conflicts, Eileen must navigate a web of psychological coercion and moral ambiguity. The narrative, told with a focus on internal tension, tracks her slow realization of the danger posed by those she initially trusted as benefactors.

Brian Moore is widely regarded for his ability to inhabit the perspectives of his characters with profound psychological acuity. Critics have frequently noted his capacity to portray the internal lives of women with a level of empathy and nuance that remains rare in the literary canon. The novel is recognized for its burning intensity and its refusal to offer easy resolutions to the moral dilemmas it presents. Readers often find the tension within the McAuley household to be both suffocating and masterfully constructed, leaving a lasting impression on the memory long after the final page is turned.
