What The Vampire Lovers is
Styria. Mid-July. A rusted lock clicks onto a coffin hinge. A young English governess arrives at a secluded estate while daughters vanish and mirrors fog red. The coachman’s neck bears two punctures. Eight years after stake and silence, someone with Mircalla’s eyes orders wine served in the crypt.
