Did Mark Twain write a book about Jesse James?
No, Mark Twain did not write a book about Jesse James. Twain DID happen to meet James once, briefly, though. You may be confusing the notion of a Twain-written James’ story with the fictional book “Jesse: A Novel of the Outlaw Jesse James” by Max McCoy which poses Jesse telling his biography to Twain who, then, writes it for him.
