What all the other reviews say. A good book.
both "Orlando in love" and "orlando mad" are packed in a very readable style by Bulfinch. Vastly superior to the more famous "king Arthur" legends in English. Charlemagnes paladins should be better known.
Not bad. A female fu Manchu is what it boils down to. As always the extremely competent villain becomes incompetent as the story progresses.
