Terence Fisher and Antony Darnborough direct Jean Simmons, Dirk Bogarde and David Tomlinson in this mystery where a a British tourist is gaslit by French hotel owners when her brother and his hotel room disappear overnight.

Sprightly British potboiler set around the 1889 Paris World Exhibition. Jean Simmons is sympathetic as a character torn between confusion, desperation and determination. It probably takes Bogarde too long to get in on the action to deserve his top billing though. A cosy wrinkle on The Lady Vanishes / Frantic format with a strong denouement.
