This is B. M. Bower's 1931 novel, "Dark Horse - A Story of the Flying U". Big Medicine was a hero among the cowhands of the Flying U after he saved the stranger on horseback who had been struck by lightning. However, their mysterious guest seemed to have amnesia and couldn't remember who he was. A fantastic sequel to "Chip of the Flying U", "Dark Horse" is not to be missed by fans of Bower's wonderful work. Bertha Muzzy Sinclair or Sinclair-Cowan (1871 - 1940), more commonly known as B. M.
