Hard Luck Money (The Loner, #14)

His father was a famous gunman. But the Loner is quiet, careful, and the perfect choice to go undercover--and the key to success is not getting slaughtered. . .
Hard Luck Money
A beautiful young woman has an incredible story to tell: about her outlaw father, how he got busted out of jail, and then met a bloody end. Katherine Lupo believes her dad, a career train robber, was sprung by someone who wanted to set up Lupo for another crime--and then killed him when the job was done. A Texas Ranger believes her. And he turns to The Loner, a man with the guile and courage to go undercover and find out who was behind Lupo's escape and murder. Posing as train robber, The Loner finds what he is after: a cold blooded and deadly master criminal. But from the get-go, The Loner is fighting for his life, for the lives of men and women on the right side of the law--and one desperate shot to plant an evil man six feet under in Boot Hill.
