Core Plot Summary

Ten people, each hiding a past crime for which they were never punished, are invited to Soldier Island by an unknown host. Upon arrival, a recording accuses each guest of murder. One by one, the guests are killed in ways mirroring a creepy nursery rhyme posted in each room. As the body count rises, paranoia and suspicion spiral, with no clear culprit in sight. By the novel’s end, all 10 guests are dead, and the island holds the secret of who orchestrated the perfect, untraceable mass murder.

Key Narrative Beats to Remember

Start with the initial arrival: note each guest’s hidden crime and their reaction to the accusatory recording. Track the order of deaths and how each aligns with the nursery rhyme—this pattern is critical for analyzing the killer’s planning. Highlight the moments of collective panic and individual attempts to uncover the truth, such as searches of the island and debates over who the killer could be. Finally, focus on the novel’s twist ending, which reveals the killer’s identity and motive for the elaborate scheme.

Study Structure for Quizzes & Discussions

For quizzes, create a quick reference chart linking each guest to their past crime, death, and corresponding nursery rhyme line. For class discussions, prepare three talking points: 1) How does isolation fuel the group’s paranoia? 2) What does the novel say about justice outside the legal system? 3) How does Christie build suspense without revealing the killer early? Practice explaining these points with specific, non-copyrighted plot details to avoid direct text references.

Essay Prep Framework

If writing an essay, pick a focused thesis, such as how the nursery rhyme acts as a symbolic framework for the novel’s exploration of guilt. Structure your essay with an intro that states your thesis, three body paragraphs each linking the rhyme to a theme (guilt, justice, or fate), and a conclusion that ties back to the novel’s status as a mystery masterpiece. Use plot events (not direct quotes) to support your claims, and end with a note on how the ending recontextualizes the entire story.
