"Remember that, Carter. Nobody double-crosses Archie Costello and gets away with it. When you least expect it, revenge will come." Without a further word, Archie stepped across the driveway, in front of the car, under the spotlight, and up to his front door. Then he was gone into the house. He left Carter there, shaken, not only by the prospect of Archie's revenge sometime in the future but what he had almost done. He'd almost turned traitor against Obie. Which meant being a traitor a second time. Not once but twice. Christ, he thought, what have I become?
