Prince of Darkness1969

A stranger has come to Middleburg, Maryland, a visitor from abroad with a mysterious purpose. But this quaint, affluent community has dark secrets of its own. And when the interloper, Peter Stewart, becomes involved with the bewitching, seductive ward of noted local author Kate More, the townfolk fear the chilling past they are hiding will no longer be safe. For Middleburg has a colonial history of malevolent sorceries and obscene sacrifice. And when the terrible pot is stirred, murder may be the least of the evils to emerge from the unholy brew.
