Was the Devil's Mark found on the skin of accused witches really the Bull's Eye Rash found on Lyme disease victims? While most historians have focused on the Salem Witch hunt as a religious or social event, this book looks for the first time at the historic landscape and environment. This past reveals a tick risky world where both accused witches and their supposed victims develop red marks on their bodies. Did the afflicted suffer from Lyme disease in the past? There are parallels between the past and modern treatment of patients who exhibit chronic symptoms and the way that some of the physicians who try to help them are viewed by society - some have them been subjected to a modern version of a witch-hunt. Using the latest in scientific and historical research this book tells a compelling tale about the timeless importance of the interactions between humanity and the "invisible world" of bacteria.
