Billy the Kid is one of the most famous outlaws ever to come out of the Old West—an expert at rustling, thieving, shooting, and breaking out of jails. Over the years, he has been the subject of hundreds of books, articles, movies, and more. Still, tantalizingly little is known about the Kid, and many questions remain. Before he died at the age of about 21, how many men did he kill? Was he a ruthless criminal or a good-hearted Robin Hood of the American Southwest? And why have his fame and legend survived for so long? Separate the fact from fiction in this new biography about Billy the Kid and how he played an important role in the legends during the settlement of the American West.
