The Hemingway Hoax

Around 1991, Haldeman wrote: ""What is the book about? The subtitle A 'Short Comic Novel of Existential Terror' is accurate. In a way, it's a horror novel tinged with ghastly humor, as the apparently insane ghost of Ernest Hemingway murders a helpless scholar over and over; the scholar slipping from one universe to the next each time he dies, in what is apparently a rather unpleasant form of serial immortality. The tongue-in-cheek explanations for how this could happen qualify the book as a science fiction novel.
... It may be the most 'literary' of my books, but it also has the most explicit sex and the most gruesome violence I've ever written. Nobody will be bored by it."
