Yellowstone plot
"THE GREAT GEYSER MURDER MYSTERY!"
Ex-con James Foster is shot dead in Yellowstone National Park while searching for a fortune in stolen money, buried there 20 years earlier by the notorious Tracy gang. Sincere park ranger Dick Sherwood is the prime suspect. Witnesses reported seeing Sherwood and Foster in a heated argument before the murder. In addition, the ranger's service revolver is missing a bullet. Desperate to clear his name and with the evidence against him, Sherwood is certain that the buried treasure holds the key to the identity of the real killer.
