Plot

Zurta and Valya are at ease in sophisticated society. 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. Poole, an accomplice, is passed the diary, but double-crosses them and attempts to flee with it on the Orient Express traveling between Paris and Trieste. Just in time, Valya and Zurta board the train, on which compartments are scarce, leading to unintended consequences.
