Homicide Detective John Decker spends his nights cruising dark gay bars and his days tracking down killers. Because of this, he maintains a distance from men, though he longs to be with someone. And then one night he meets a handsome, pale man named Alexander Holt. Decker sees reflected in Alexander's eyes his own world-weariness and invites the man back to his apartment. In the days following the encounter, Decker experiences vivid, erotic dreams about Alexander as he suffers from a sudden bout of what he thinks is the flu. But then the crazy homeless man outside his apartment accuses him of having been tainted by the Dark Master, and Decker notices strange marks on his throat. As the evidence of what Alexander truly is comes into focus, Decker realizes he's gotten more than he expected from his kindred spirit.
