Travelling home from a European holiday, Iris Carr ends up alone at the station after a quarrel with her friends. Struck by a mysterious assailant and waking up just in time to board the train which will take her on her journey to London, things seem to be looking up after a chance meeting with the affable Miss Froy. But when Iris passes out and reawakens, Miss Froy is nowhere to be found. The other passengers deny any knowledge of her existence and as the train speeds across Europe, Iris spirals deeper and deeper into a strange conspiracy. Adapted for the screen as The Lady Vanishes by Alfred Hitchcock in 1938, Ethel Lina White's suspenseful mystery remains her best-known novel, worthy of acknowledgement as a classic of the genre in its own right.
