This volume contains Edgar Allen Poe’s 1835 short story, “The Unparalleled Adventure of One Hans Pfaall". It is the story of Hans Pfaall, a man who claims to have visited the moon in a new type of balloon with the aid of an instrument that allowed him to breathe in a vacuum. Upon arrival, Pfaall withholds information about the residents of the moon in an attempt to leverage a pardoning for a string of murders that he previously committed. A fantastic and masterfully-composed tale, “The Unparalleled Adventure of One Hans Pfaall" will appeal to fans of vintage science fiction. Edgar Allan Poe (1809–1849) was an American author, editor, poet, and critic. Most famous for his stories of mystery and horror, he was one of the first American short story writers, and is widely considered to be the inventor of the detective fiction genre. Many antiquarian books such as this are becoming increasingly rare and expensive. We are republishing this volume now in an affordable, high-quality edition complete with a specially commissioned new biography of the author.
