Longarm and the Arizona assassin

the long version

"When a beautiful Indian woman drops into Deputy Marshal Custis Long's arms with a bullet hole in her head, he vows to find her murderer. But it's the dead of winter and Longarm's cold is bordering on pneumonia--until he receives a home remedy from Swedish nurse Olga Swenson. Once he's fit as a fiddle, Longarm boards a train bound for Flagstaff. He's trailing the shooter to Navajo country in Arizona, but first there is the little federal matter of someone going postal on a Flagstaff postmaster. Taking on twin outlaws, Longarm dispenses some double-barreled justice, never losing sight of his single-minded purpose--catching the coward who took a woman's life."--Page 4 of cover.
