Beautiful and wealthy young socialite Iris Carr is used to being at the heart of her social group but when her friends’ raucous behaviour escalates whilst on holiday in the Balkans she resolves to seek out some tranquillity and travel home alone.
But her expectations of peace are short-lived when at the railway station Iris wavers in the scorching heat and constant jostle of passengers, fainting suddenly on the platform. She wakes in time to be rushed on to the train but with a pounding head and a feeling of being almost in a dream.
Whilst in this malaise she is comforted by an older English lady called Miss Froy, whose tweed suit and bookish looks hide a surprisingly jovial and adventurous spirit. She talks at length about her employer and her desperation to return home to her family but when Iris falls asleep she awakes to find Miss Froy vanished and her fellow passengers denying she ever existed.
With only the friendship of handsome English traveller Max Hare for support, Iris maintains her conviction that Miss Froy has somehow been abducted. But who would want to snatch a seemingly harmless English woman and where would she be hiding?
As fellow passengers refute Iris’ story and figures emerge who will disprove Miss Froy’s existence, Iris’ conviction appears increasingly to be madness. With only Max to help her Iris will have to rely on a strength of character she never knew she had to battle doubt and overcome danger as she strives to solve the mystery of why the lady vanished.
