Otto Penzler presents a collection of nineteen unsolved mystery stories by a number of noted authors, including Ray Bradbury, Roald Dahl, and Mark Twain, where the ending is left up to the listener to determine. Here are the most intriguing riddle mysteries in literary history, including tales from Bradbury, Dahl, Huxley, O. Henry, and Twain. Tantalizing, as ingenious as they are devious, the classic stories in this continually arresting collection come with an irresistible challenge: At their end they leave it to you, the listener, to determine how they end. For ultimately it's the listener who authors the fate of the brave youth as he contemplates which of the two doors in the king's arena he will choose in Frank Stockton's famous and unforgettable "The Lady, or the Tiger?" And which of the two brothers in three-time Edgar-winner Stanley Ellin's "Unreasonable Doubt" shoots a bullet square in the middle of their rich uncle's forehead? And just what not-so-sweet secret is the prim Miss Spence hiding behind her smile in Aldous Huxley's deliciously enigmatic tale? You decide.
