A retired university lecturer hires a caregiver, setting in motion a collision between a fragile present and a violent, long-buried past. Nina Rawle, suffering from lupus, invites Joan Douglas into her home, unaware that her own history of radical activism in Belfast remains a ticking clock. The narrative alternates between the present-day domestic dynamic of the two women and a series of epistolary confessions Nina writes to a former associate. As Joan prepares for a new life with a man recently released from prison, Nina’s past actions threaten to dismantle the stability they have tentatively built together.

Critics have noted that the novel succeeds through its vivid characterizations and the intensity of its prose. While some reviewers have pointed to occasional pacing issues or moments of contrivance, the strength of the central relationship between Nina and Joan remains a focal point of discussion. The book is frequently cited for its ability to balance a domestic setting with the darker, more visceral history of political unrest. Readers often find the psychological depth of the protagonist to be the primary driver of the narrative tension throughout the story.
