When Miss Alvina Lockwood came along and begged him to bail her “innocent” brother out of a horse-stealing charge, he checked up on her story—though maybe not as closely as he would have if she weren’t such a tempting tidbit. But when a sting operation set up to capture the real thieves goes awry, Longarm’s left wondering about Alvina—and her possible connections to a bandit known only as Kansas City Red. It seems Red is a fiery—and clever—little filly who’s got people on both sides of the law chasing their tails. But Longarm learns from his mistakes, and he won’t get fooled again. After all, there are plenty of pretty ladies in the West, but a man can’t sow his oats when he’s planted six feet under…

With some dirt on his targets gathered from a lonely, young landlady—who’ll only give away one secret per night of low-down lovin’—Longarm thinks he can sniff out their track.
