The next day they are almost at the appointed spot when there is a cry of "Fire!" The two rush out in the corridor where a Slavic woman is pointing to the smoke coming out of one of the compartments further down the train. The conductor assures the passengers that there is no emergency but, suspicious, Pyne returns to Elsie's compartment and finds the Slavic woman there, supposedly recovering from the shock but Pyne refuses to let her leave when she wishes to and, when Elsie returns, asks her to sort through her belongings. She does so and finds that her jewellery has gone. The Slavic woman is detained at Venice but the jewels are not found on her and she has to be released. On the way to Trieste, Pyne and Elsie discuss the puzzle of where the jewels could possibly be as no one else had the opportunity to take them and the Slavic woman could not have thrown them to someone outside the train as they were on the bridge passing over the sea and they have not been hidden in the compartment. Pyne decides that he must send a telegram at Trieste...
