This novel, when originally published in 1936, was entitled The Wheel Spins. However, since the Alfred Hitchcock film adaptation in 1938, the novel has become better known by its 'Hollywood name' The Lady Vanishes. The novel tells of a beautiful English tourist travelling by train in Europe who discovers that her elderly travelling companion seems to have disappeared from the train. After her fellow passengers deny ever having seen the elderly lady, the young woman is helped by a young musicologist, and the two proceed to search the train for clues to the old woman's disappearance. This edition also includes the novel originally published as Some Must Watch, now better known as The Spiral Staircase from the subsequent film adaptations.
