Horror Comes to Haddonfield

From the introduction: When the village of Haddonfield discovered that the wizard Langenkamp was engaged in dark magic, they raised a mob and burned down the old windmill in which he dwelled. With his dying words, Langenkamp laid a curse on the villagers who sought his doom, a curse which would have come to nothing had Cropsy, a young farm labourer, not sneaked into the mill for a nap and been caught in the conflagration. The death of an innocent provided the mystic fuel for the curse, and now the people of Haddonfield are trapped with no hope of rescue.
