Parnassus on Wheels Christopher Morley When you sell a man a book, says Roger Mifflin, the sprite-like book peddler at the center of this classic novella, you don’t sell him just twelve ounces of paper and ink and glue–you sell him a whole new life. In this beguiling but little-known prequel to Christopher Morley’s beloved Haunted Bookshop, the whole new life that the traveling bookman delivers to Helen McGill, the narrator of Parnassus on Wheels, provides the romantic comedy that drives this charming love letter to a life in books.
