Homicide detective Harry Picard had seen a lot of violent deaths... but never like this. Three bodies—blonde, female, strangely emaciated—were found in the Potomac River with their throats brutally slashed. Each had been seen in the company of a huge, hulking man dressed in black. Picard's investigation catapulted him into a roiling morass of passion, sexual intrigue, violence, and primordial fear... as he faced an enemy as powerful, and as horrifying, as man's oldest superstitions!

First published in 1965, Leslie H. Whitten's Progeny of the Adder updated the traditional vampire tale by bringing the undead out of the Old World and into a police investigation in a large American city for the first time—a formula often imitated in the decades since. This reprint, the first in thirty years, includes a new introduction by Will Errickson.
