LADY KILLER The name makes cavalrymen cower, hard cases head for the hills, and bandidos cry, ''VAmonos!' They call her SeNorita Revenge. Savage and merciless, she and her band of kill-crazy Kiowa have been cutting down soldiers like blades of grass in the Texas Big Bend country north of the Rio Grande. If any man can de-claw this homicidal hellcat, it's U.S. Deputy Marshal Custis Long. But when Longarm arrives at the cavalry outpost, he finds a half-mad major, his batty blond daughter, a horribly scarred captain, and a mouthwatering but mysterious maiden each of whom is hiding a secret. As Longarm puts the pieces together, he draws ever closer to ending this beautiful buckskin-clad butcher's reign of vengeance.
