This book explores and examines twenty-one of the Old West's most baffling mysteries. Many relate to the death or disappearance of some of the best-known lawmen and outlaws in history, such as Billy the Kid, Buckskin Frank Leslie, John Wilkes Booth, The Catalina Kid, and Butch Cassidy. Others involve mysterious tales and legends of lost mines and buried treasures that have not been recovered--yet.
