The series is based on an Elmore Leonard novella, "Fire in the Hole." It is included on Leonard's short story collection, "When the Ladies Come Out to Dance."
Raylan Givens is the feature character in two earlier Leonard novels. 1993's "Pronto" introduced Raylan. Leonard brought Raylan back in 1995's "Riding the Rap."
Both are set in Florida...Raylan is a US Marshall based in Palm Beach County.
It has been years since I read either novel. Both were keepers, so I have dusted them off and made them part of my summer reading program.
