Gunfight at Comanche Creek

Summary

Comanche Creek, Colorado, 1875: Prisoner Jack Mason is broken out of jail by a gang of strangers. They use him in a robbery, then when the dead-or-alive reward is high enough, they shoot him and collect. The National Detective Agency, now knowing the gang's methods, arranges to have agent Bob Gifford jailed in Comanche Creek for train robbery. The gang takes the bait (not before Gifford catches the eye of lovely saloon-keeper Abbie). But how will the bait get off the hook?
