The late nineteenth century was something of a heyday for inquiries into the supernatural, replete with spiritualists, seances, mediums, and purported communications with the great beyond. In this volume, Allen Putnam attempts to project the tenets and beliefs of the spiritualism movement back onto the events that transpired in New England centuries before in order to gain new insight into the accusations of witchcraft that define that moment in history.
