Finding Misery — Russell C. Connor

Rudy Compton's going through what you might call a 'rough patch.' He just found out his wife's cheating on him and now, he's spending the night in county lockup. Unfortunately, he's not there alone. Before the night is over, he'll survive a brutal rampage by a fellow inmate, and pick up a piece of information that will make him--and everyone around him--a target. Soon he'll find himself pursued by a duo of mobsters that just won't die, a cult of crazed medieval warriors, and a lone government agent that can't tell him the truth. Rudy's only choice will be to go on the run to Reno with the cops in hot pursuit and his estranged wife in tow, where he'll either find what he needs to clear his name...or get both of them killed.
