This biography investigates the life and public persona of Agatha Christie, specifically focusing on the motivations behind her unexplained eleven-day disappearance in 1926. Gwen Robyns, a journalist and biographer, utilizes archival research and interviews to construct a portrait of the author that separates the private woman from the public figure. The text examines the pressures of fame and the personal circumstances that may have influenced Christie's behavior during this period of intense media scrutiny.

Critics often note that this work serves as an early attempt to humanize a notoriously private figure, though some scholars suggest it lacks the depth of later, more academic biographies. It remains a frequently cited source for those interested in the specific historical context of the 1926 event.
