Back Cover Summary
Karen lives next door to an old lady named Mrs. Porter. Mrs. Porter wears long black robes and has wild gray hair. Her black cat is named Midnight. No wonder Karen thinks Mrs. Porter is a witch!
Mrs. Porter is having a meeting at her house. Karen is sure the meeting is for witches.
Are the witches going to cast a spell on Karen? Or will she be brave enough to send them away — once and for all?
Karen is convinced that her next door neighbor Mrs. Porter is a witch. One "big house" weekend, Karen spends a lot of time spying on Mrs. Porter in her herb garden. She gets herself worked up and scared that Mrs. Porter is going to hold a large witch meeting. On the Sunday afternoon, Karen sees several cars come up to Mrs. Porter's house with various people in them. Karen is convinced the witch meeting is happening and so she and Hannie go next door to confront the "witches." Upon getting into the meeting and chanting made up spells, Karen and Hannie realize they have insulted the members of the Stoneybrook Gardeners Club, including Karen's grandmother. She marches the girls home where Elizabeth and Watson force Karen to write a letter of apology to Mrs. Porter and make Karen promise to not spy on the neighbors again.
