"No scholar has done more to illuminate the terrifying psychology of witchcraft in Western culture than John Demos. The Enemy Within is a masterful synthesis of this phenomenon, stretching over 2000 years, from its origins in Europe through the Salem witch trials, the Red-hunting campaigns of Senator Joe McCarthy, and the modern-day hysteria surrounding Satanic cults and sensational child abuse charges. An elegant writer, a brilliant historical investigator, Demos is the perfect guide for this rich and fascinating journey." --David Oshinsky, winner of the 2006 Pulitzer Prize in History for Polio: An American Story and author of A Conspiracy so Immense: The World of Joe McCarthy “Only John Demos could write this book! In succinct and well-written chapters, Demos introduces readers to the ways in which anger and fear have caused western societies to turn inward in panics we now call witch-hunts. The Enemy Within , simultaneously sweeping and specific, broadens Demos's earlier work on witchcraft in seventeenth-century New England into a thought-provoking and wide-ranging study.” --Mary Beth Norton, author of In the Devil's Snare “A searing story, and a remarkable read. Unlike most historians, Demos does not flinch from taking us up close to real characters. We see the world through the eyes of men and women accused of witchcraft by neighbors they had known for years, as he probes the psychodynamics at work in this terrible experience.

In a distillation of a lifetime's research, Demos, who is the foremost scholar of early American witchcraft, reveals patterns that go back to the European middle ages and explains how shifting interpretations of Salem reflect its place at the heart of the American psyche.” --Lyndal Roper, Professor of Early Modern History, Balliol College, Oxford.
