First published between 1930 and 1956, the six novels written by Agatha Christie under the name Mary Westmacott, regarded by some as the writer's finest work, show a very different side of her talent. What they share with her other fiction is Christie's gift for sharp observations about people, the ambitions that drive them, their relationships, and the conflicts that erupt between them.

Stranded between trains, Joan Scudamore finds herself reflecting upon her life, her family, and finally coming to grips with the uncomfortable truths about her life.
