The Canterville Ghost, adapted by Caroline Castle for the Oxford Reading Tree's high-level Stage 14 TreeTops Classics series, is a simplified version of Oscar Wilde's humorous and witty short story. The narrative centers on an American family, the Otis family, who purchase an ancient, haunted English mansion. The resident ghost, Sir Simon de Canterville, a genuine, old-fashioned specter, is furious when his centuries of frightening tradition are completely undermined by the practical, modern Americans, who treat his haunting efforts with complete indifference or simple household products. This adaptation retains the original's humor and charm while making the sophisticated language accessible to advanced primary readers. It serves as a tool for transitioning children into complex literature, promoting themes of cultural clash, the contrast between old and new, and the true meaning of peace and redemption for the tragic ghost.
