Lampert, Laurence.  Nietzsche's Teaching: An Interpretation of Thus Spoke Zarathustra. New Haven: Yale University Press, 1986.

From the Publisher:

“The first comprehensive interpretation of Nietzsche’s “Thus Spoke Zarathustra” — an important and difficult text and the only book Nietzsche ever wrote with characters, events, setting, and a plot. Laurence Lampert’s chapter-by-chapter commentary on Nietzsche’s magnum opus clarifies not only “Zarathustra’s” narrative structure but also the development of Nietzsche’s thinking as a whole.”
