Kate Fisher

Kate Fisher was a singer at the Last Chance Saloon in Tombstone, Arizona and the girlfriend of Doc Holliday. She tried to persuade him not to fight Ike Clanton and his brothers in October 1881.

Kate helped Doc disguise the First Doctor as himself. At the saloon, she pretended to the Clantons and Seth Harper that the Doctor was Holliday. She and Holliday left town when Wyatt Earp was "gunning" for Holliday. They took Dodo Chaplet with them, but when Holliday had to return to Tombstone, he left Kate behind for safety. She ran into Johnny Ringo and pretended that Holliday had left her for Dodo.

After the gunfight at the O.K. Corral, Kate and Holliday left Tombstone together. (TV: The Gunfighters)
