Wait, "l amica viziosa" translates to "The Wicked Friend" in English. Maybe it's a book? I recall that "The Wicked Friend" is a book by Anthony Browne, published in English in 1989. It's a children's novella about two girls, Tilly and Annetta, and their friendship. But the title here includes "Zelica Martinelli," which I don't recognize as part of that book. Maybe it's a different work? Or perhaps it's a mistranslation or a localized version?
