Sleeping Car to Trieste is a 1948 British comedy thriller film directed by John Paddy Carstairs and starring Jean Kent, Albert Lieven, Derrick De Marney and Rona Anderson.

Zurta steals a diary from the safe of an embassy in Paris while they are guests at a reception there, killing a servant who walks in on the theft.

Other travelers on the train, some of whom become involved incidentally in the intrigue, include a US Army sergeant with an eye for the ladies, an adulterous couple, a pestering stockbroker, an arrogant and wealthy writer, his brow-beaten secretary, an ornithologist, and a famed French police inspector.

Just when it is successfully completed, Zurta takes it at gunpoint and leaps from the train…not safely onto the tracks but unknowingly immediately in front of a passing express.

[6] The New York Times wrote, "not without its trying moments, but on the whole it is a mighty interesting ride...The director John Paddy Carstairs shrewdly maneuvers the pursuers and the hunted about the train in a natural and credible manner so that the possibility of an imminent meeting creates a good deal of tension...None of the principals is too familiar to audiences here, and at times dialogue is lost in some of the players' throats, but the performances are generally satisfying.
