Ten strangers, each invited under a different pretext, arrive on an isolated island off the Devon coast. None of them has met their absent host, the elusive U. N. Owen, and as the boat that brought them departs, they settle in for what promises to be an unusual stay. After dinner on the first evening, a recorded voice fills the room, accusing every guest of having caused a death and escaped justice. Soon afterward, one of them dies. As a storm cuts the island off from the mainland, the remaining guests realize their deaths are being staged to mirror the verses of an old nursery rhyme that hangs framed in each bedroom. One by one, the survivors fall, and with no way to summon help and no sign of any other living soul, suspicion turns inward. Each person studies the others, certain that the killer is among them, while the rhyme counts steadily down. Trapped, watched, and unable to trust anyone, they must reckon with the secrets that brought them here even as the circle of the living shrinks. Christie builds a closed, methodical puzzle in which guilt, fear, and isolation press on every character, and the question is not only who will be next but how anyone could orchestrate such a sequence of deaths on a deserted island. It is a tightly constructed account of crime and consequence with no series detective to set things right.
