The Lady Vanishes & The Spiral Staircase 12539

This novel, when originally published in 1936, was The entitled Wheel Spins. However, since the Alfred Hitchcock film adaptation in 1938, the novel has become known better 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.
