Before Vampirella was marked by the Cult of Chaos as a living sacrifice to Lady Umbra, Queen of Shadows, she worked as an field operative for Cestus Dei, the Vatican's version of MI-6. In this one-shot, set before the "Our Lady of Shadows" story arc (from Vampirella #1-6), Vampirella must go undercover at a French convent to investigate a series of weird deaths and odd disappearances believed to be the work of a long-dead evil witch known as Metifa, Satan's Mistress. That's right - one of the classic Warren-era menaces makes her modern age debut, with bestselling horror author Nancy A. Collins at the helm!
