Crosshairs by Harry Hunsicker
All he wants is a normal existence away from the assorted lowlifes inherent to his former profession as a private investigator. Unfortunately, peace and solitude are hard to find for Lee Oswald, now weary after a decade as the fix-it man on the back streets of Dallas. But when a medical researcher begs him to help find the person threatening her daughter's life, Oswald returns to the shadowy world he'd tried so hard to leave behind. He is soon engaged in a high stakes battle against a man known only as The Professor - a former intelligence operative, and an enemy more deadly than Oswald's ever faced. Hailed by reviewers, Hunsicker is a skilled noir writer whose cast of characters leap off the page as Lee Henry gigs deeper and deeper into the crime world of Texas.
