Sunset trail a western duo

"A U.S. agent must stop a shipment of rifles from reaching the Comanche in New Mexico; and, the people of Amity, Colorado, become pawns in an assassination plot against the governor."
"Contains two short western novels including "Sunset Trail," in which government agent and frontiersman Bruce Shane is sent to locate a contraband shipment of rifles in 1846 only to find himself framed for murder; and "Twelve Hours Till Noon" in which rancher and local banker Matt Dugan invites the governor to speak at the opening of a dam in Amity, Colorado, in 1893, and unwittingly opens his family and the governor up to an attack by assassins."
"In the first story, a government agent tries to locate contraband rifles of the eve of the Mexican-American war. In the second story, during the Panic of 1893, the assassination of the governor of Colorado is planned during his speech to a small town."
"A U.S. agent must prevent a shipment of rifles from reaching the Comanche in New Mexico. Surrounded by enemies and accused of murder, he'll be lucky to make it to Santa Fe alive. And in Twelve Hours Till Noon, the people of Amity, Colorado, are stunned at the robbery of their local bank. But little do they know the "robbery" is only a cloak for a much bigger plan: assassinating the governor. The clock counts down as the tension rises."@en
