But with no outlet other than vodka, her sorrow is close to driving the hyper-rational Catherine mad. The only person who knew of their affair--her boss--tries to distract and rescue her by giving her a project that demands all of her attention: the reconstruction of an elaborate nineteenth-century automaton.
