Oscar Case began writing near 70 years old, producing several books on family history and genealogy before switching to Western fiction. He has written a dozen Westerns, including a book of short stories. Blood and Blazes in Upamona was his third novel and part of a series set in the vicinity of Upamona, a fictional town located in the foothills of the Uinta Mountains in northeast Utah.
Slim Sanglant, released from prison, is seeking revenge against those in Upamona who helped send him to jail. Red Skene, County Sheriff, is on his trail. There is a killing, houses and a barn are set on fire, and people are missing before Red can get to the bottom of it with the help of his half-breed Deputy, Bushy Carlsen.
