Mack and Denise Rattray were local drug dealers in Bon Temps, specializing in V. In the Charlaine Harris novel, Dead Until Dark, Sookie reads their minds and reveals that they had both been in prison for vampire draining. She says Denise had abandoned a baby two years prior and the baby wasn't Mack's. They serve as minor antagonist in season 1.
In an attempt to drain Bill Compton of his blood to sell, the Rattrays were stopped by a chain-wielding Sookie in the parking lot of Merlotte's. ("Strange Love") Having sworn revenge, the Rattrays returned the following night and began to mercilessly beat Sookie outside Merlotte's.
Bill came to her rescue and killed the Rattrays, saving Sookie from what would have been a fatal beating. The following day, the Rattrays were mysteriously found crushed to death by their trailer supposedly having been hit by a tornado. Bill later admitted to Sookie that he fed on and crushed them. ("The First Taste")
At the end of season 3, Eric reveals to Sookie that Bill purposely allowed the Rattrays to beat her to a point of near death, just so he could give her some of his blood. Bill admits that this is true, prompting Sookie to rescind both Bill's and Eric's invitation into her house. ("Evil is Going On")
