The exciting original of the Hitchcock film classic.
Iris Carr was young, wealthy, attractive – and bored. Despairing of her society friends, tired of skiing with the crowd, she decides to return to England alone by train. But she hadn’t bargained for the extraordinary Miss Froy – a lively, gossipy spinster who is determined to befriend her, nor had she expected Miss Froy’s sudden disappearance.
Certain that she has not imagined so bizarre a character, and outraged by the blank faces of the passengers who deny her existence, Iris vows to find her companion, unaware of the terrifying trail ahead, so wildly different from her notion of a comfortable journey home.
