Dead Reckoning and Last Chance — Mike Blakely

Dead Reckoning
After a botched confidence scam, swindler Dee Hassard begins a killing spree that covers half the Colorado Territory. His first victim is the brother of rustler-turned-preacher Carrol Moncrief, who falls back on his former outlaw savvy to track the murderer. In the final reckoning, either the preacher or the killer will go to his dusty death.

The Last Chance
Ross Caldwell is on the run from the Army and from his wife, pursued by bitter enemies from the Civil War. In Last Chance Gulch in the gritty Montana gold country, Caldwell finds refuge behind a sheriff's badge, and passion in the arms of a sultry madam. His bloody past catches up with him when the town's stagecoach turns out to be run by the murderous ex-soldier who's sworn to plant Caldwell six feet deep ... and when his wife comes looking for him as well.
