In 1692 Salem, Massachusetts, witnessed one of the saddest and most inexplicable chapters in American history.

When a group of girls came down with a horrible, mysterious bout of illness, the town doctor looked in his medical books but failed to find a reasonable diagnosis. Pretty soon everyone in town was saying the same thing: The girls were ill because they were under a spell, the spell of witchcraft! And still, the question remains: Why did the hysteria occur? The townspeople had many things to worry about back then: smallpox, strife with the local Indians, a preacher demanding higher wages, and the division of land in the community. But did all of those problems justify a witch hunt?

Become a detective as you read this true story, study the clues, and try to understand the hysteria! The Unsolved Mystery from History series is written by acclaimed author Jane Yolen and former private investigator Heidi Elisabet Yolen Stemple. This is an innovative history lesson that's sure to keep kids thinking throughout.
