Francesca, one of her former students, works tirelessly as Lydia’s factotum [fækˈtoʊtəm], amanuensis, and personal assistant, in the expectation of becoming her assistant conductor in Berlin.

factotum
noun [fækˈtoʊtəm]

A factotum is a person who has many diverse activities or responsibilities, and especially one whose work involves a wide variety of tasks.

"Do everything!" That's a tall order, but it is exactly what a factotum is expected to do. It's also a literal translation of the Latin phrase fac tōtum: the phrase is usually glossed as "do all!" with the punctuation expressing the force behind the command.
