Bordersnakes — James Crumley

ONE GOT SHOT. THE OTHER GOT MAD.
Someone took all the money Milo's daddy left for him. Someone shot Sughrue in the stomach and left him to die. Now, the two toughest private eyes ever to come from Montana are driving a massive El Dorado through Texas, looking for revenge, and finding out how far they're willing to go for each other.

James Crumley, the author who reinvented the hard-boiled genre, sends his two antiheroes, C.W. Sughrue and Milo Milodragovitch, on a journey of blood, booze, and betrayal that stretches from Austin to the Rio Grande. And for the two men who know all about broken hearts and broken rules, borders don't mean a damn thing...
