Part of the Mavenhill Classics series, this annotated edition of The Mysterious Affair at Styles presents Agatha Christie’s groundbreaking debut novel alongside clear, chapter-by-chapter summaries that illuminate the plot, characters and themes as the mystery unfolds. At Styles Court, a quiet English country house secluded by lawns and hedges, appearances are carefully maintained and secrets are carefully kept. When the formidable and wealthy Emily Inglethorp dies suddenly in her locked bedroom under circumstances that defy easy explanation, the ordered world of the household fractures. What seems at first like a tragic illness quickly reveals itself as something far more sinister.
