A late night vampire attack on a young woman, Ann Allen, is assigned to
veteran police detective P. L. "Dutch" Brinker. At first Sergeant
Brinker dismisses the attacker as a "'crazy' with a good act". As the
investigation proceeds, however, circumstances force Dutch to admit he
is dealing with an occult foe. Assisting him to realize the bizarre
nature of the case, is the laboratory research of criminologist Dr.
Harvey "Mad Harvey" Nelson. Harvey's research shows that vampire's are
not a myth, and that their condition is not a curse but a disease-one
that carries with it supernatural powers and an evil nature. As Dutch
and Harvey race to find and destroy the vampire before Ann succumbs and
becomes a vampire herself, they are confronted with a vast underworld of
the occult that infiltrates and influences governments, businesses, and
the criminal underworld-even religious organizations. A world of
shadows-shadows of evil.
