Réalisation: Alfred Hitchcock
Dans le train qui la ramène des Balkans chez elle, Iris se lie avec une vieille dame, Miss Froy. Or celle-ci disparaît pendant le sommeil d'Iris : à sa place se trouve une autre dame portant les mêmes vêtements. Aucun passager du train ne se souvient de Miss Froy. Assistée par un jeune musicien, Gilbert, Iris mène l'enquête.
