Following the sudden death of her husband in the scenic landscape of Madeira, a disabled woman finds her quiet life upended by a series of increasingly dangerous events. Roberta Ellison, isolated by her physical limitations and recent widowhood, seeks solace in the arrival of her half-sister, Camilla, only to discover that Camilla’s presence invites a web of deception. As the domestic staff becomes a source of suspicion rather than support, the sisters are drawn into a sequence of violent occurrences that threaten their safety. The narrative unfolds with a focus on the claustrophobic tension of their island residence, where every interaction is colored by the looming threat of murder.

This novel reflects the classic style of mid-century British mystery writing, characterized by a focus on character dynamics and the subtle erosion of domestic security. The premise suggests a narrative that relies on the contrast between the idyllic setting of Madeira and the encroaching darkness of the central crime. Readers of the genre will likely note the author's emphasis on the psychological vulnerability of the protagonist as she navigates her new, precarious reality. The story functions as a study in how seemingly trivial personal problems can escalate into life-threatening situations within a closed social circle.
