It's time for the girls to act. They carry out their various tasks and manage to get into Negri's studio. Eva makes a beeline for the safe. Eva is disguised, and is described by her friend as the Befana. Befana is a corruption of Epifania (Epiphany) and, in Italian tradition, the Befana is an old woman who brings gifts (or coal) for children on this holiday. Befana has also come to mean "witch."
