“While most historians of witchcraft have focused on the early modern and Renaissance era, Pennick goes beyond the great conflagrations of Europe to show how magic and witchcraft survived into the twentieth century. Operative Witchcraft offers one interesting tidbit of forgotten magical history after the next--not a page went by that I didn’t stop and say, “Wow!” Well written, well researched, a fantastic addition to any witchcraft library.” (Thomas Hatsis, author of The Witches’ Ointment)
