Veruschka is a character in 80 Days. She is a Russian doctor, rebel against the Tsar, and an escaped convict.
Veruschka claims to have been arrested and re-arrested many times for her part in the peasant revolutions against the Tsar, and has made multiple escapes.
At one point in her life she was studying to be a doctor in Switzerland, but she gave up on her profession to return home to Russia and help her people who were suffering under the Tsar's rule, who she cares for despite being of a higher social standing than most of them.
After her most recent escape from one of Russia's infamous prison camps she runs into Phileas Fogg and Passepartout while they are traveling with a Mongol caravan to Urga. Outside of the city she asks to be left behind so she can wait until nightfall and sneak into the city alone, not wanting to put them in danger. Passepartout can decide whether to do what she asks or instead disguise her as a member of the caravan and risk sneaking a wanted criminal past the Cossack troops standing guard. From Urga she plans to find passage elsewhere and expose the reality of the Tsar's brutal prison camps to the rest of the world.
