Where, Carlos Fuentes asks, is a modern-day vampire to roost? Why not Mexico City, populated by ten million blood sausages (that is, people), and a police force who won’t mind a few disappearances? “Vlad” is Vlad the Impaler, of course, whose mythic cruelty was an inspiration for Bram Stoker’s Dracula. In this sly sequel, Vlad really is undead: dispossessed after centuries of mayhem by Eastern European wars and rampant blood shortages. More than a postmodern riff on “the vampire craze,” Vlad is also an anatomy of the Mexican bourgeoisie, as well as our culture’s ways of dealing with death. For—as in Dracula—Vlad has need of both a lawyer and a real-estate agent in order to establish his new kingdom, and Yves Navarro and his wife Asunción fit the bill nicely. Having recently lost a son, might they not welcome the chance to see their remaining child live forever? More importantly, are the pleasures of middle-class life enough to keep one from joining the legions of the damned?
