Cult of the Iron Cobra — Ron Stillman

Years after discovering a strange and powerful pattern of simple numbers - a cousin of the Fibonacci Sequence - a New York University professor proves that this unique pattern formed the birth of the first vampire, the "Blood Countess" Elizabeth Bathory of Hungary. The genetics of this mathematically mutated blood cell division created a need for the Countess to drink the blood of others, and her inbred ancestry caused a deviant sexual sadism that resulted in her torturing and murdering over 600 young female virgins to slake her bloodthirst. Four hundred years later, Elizabeth, history's original vampire, finally finds a direct descendant. She is a young woman who is in love with the professor's best friend. As a dangerous lesbian vampire/changeling/human love triangle develops, the strong as iron cult that Elizabeth has formed over the centuries begins to weaken from the inside. Only the power of the number pattern can undo the deadly havoc that it originally caused. if that power can be harnessed in time. This is the first story in literature of film that has offered a genetic explanation of how the vampire came into existence.
