When Adrian Rookwhistle inherits an elephant named Rosy, his quiet life is upended by the animal's penchant for alcohol and chaos. Adrian attempts to leverage Rosy's supposed theatrical talents to escape his mundane existence in a city shop, but his plans are thwarted by the elephant's unpredictable behavior. As they travel toward the South Coast, Rosy leaves a trail of destruction that disrupts local hunts and stately homes alike. The narrative follows their escalating conflict with the local constabulary, culminating in a courtroom trial that tests the limits of logic and law.

This novel is widely regarded as a lighthearted display of the author's signature wit and observational humor. Readers often note the absurdity of the premise, which leans heavily into the tradition of British comic fiction. The narrative is frequently praised for its ability to maintain a brisk, chaotic pace that mirrors the unpredictable nature of the titular elephant. While the story is presented as an almost true account, the reception highlights the author's skill in crafting a farce that remains grounded in its own internal logic.
