The second volume in the investigation of strange esoteric circumstances surrounding seven curious and questionable deaths in 1915 San Bernardino Valley.

Along with bizarre circumstances linking two of the victims to the airship milieu, the possible identity of one of the victims also appears to bring the legendary outlaws Butch Cassidy and the Sundance Kid into the mystery.
