Shadow Man — James D. Doss

TROUBLE SPREADS ITS WINGS
Dr. Manfred Blinkoe is one orthodontist with a very checkered past. So when a fellow diner at Cedar Creek's poshest restaurant drops dead from an unseen assailant's bullet, he can't help thinking that he was the intended target. Desperate for help, he turns to the one local who's up to the job: renowned tribal investigator Charlie Moon.

AND A KILLER COMES TO ROOST
Charlie already has his hands full with two cattle ranches to run, ornery Aunt Daisy's wanderings in the spirit world, and his sparring matches with the alluring FBI agent Lila Mae McTeague. Now he's got an eccentric client with more money than sense and too many enemies--at least one of whom is willing to resort to explosive measures to settle an old score.
