A Noite de Walpurgis.

A Noite de Walpurgis is a fantastic tale by Hugo Rocha, admittedly inspired by Goethe's Faust. The narrator-protagonist reveals a story told to him by a third person. Here the third person is an old peasant woman that the protagonist finds in a walk through the mountains, and that tells a story that in turn would have been told to her by the grandmother.
