A meticulously planned dinner party intended to bridge the gap between a man's mistress and his social circle descends into a chaotic hostage situation. Binny, the mistress, seeks a sense of belonging and validation through this intimate gathering, hoping to secure a more permanent place in Edward's life. However, the arrival of uninvited, aggressive guests shatters the fragile social veneer, trapping the participants in a claustrophobic environment. The narrative, characterized by sharp, observational prose, tracks the rapid disintegration of social norms as the characters confront their own vulnerabilities and the absurdity of their predicament.

This work is often cited as a quintessential example of the author's ability to blend domestic realism with a sense of impending dread. Critics frequently point to the novel's economy of language and its capacity to extract profound psychological insight from a singular, contained event. The narrative is noted for its refusal to provide easy resolutions, instead leaving the reader to contemplate the moral ambiguities of the characters' choices. The text remains a significant entry in the author's bibliography for its unflinching look at the intersection of social performance and personal desperation.
