Let Sleeping Evils Lie

Exercising an evil spirit is not the easiest of undertakings, especially when it involves exorcising the marshes around the ruins of Ashley Manor in Norfolk, and more especially when the girl you are exorcising the spirit because of says she believes the spirit you are exorcising isn't evil, but is protecting her from something else, and that you should stop doing what you're doing to get rid of it.You go ahead anyway and when it's too late, discover the girl was right, and that something far worse, a centuries-old evil, involving a pact with the devil was lurking in the background just waiting for its chance when set free. And being set free proves almost impossible to control.
