When we first meet David in the series, he's a 65-year-old Englishman whom Lestat befriends (and harasses, but that's not much of a surprise). In Tale of the Body Thief, however, David, in a Rube Goldberg-styled plot, ends up in the gorgeous body of a 26-year-old Anglo-Indian male. Then Lestat forcibly makes him into a vampire.
