"When people do the rounds a second time to check doors, windows and locks that were supposedly closed, they'd find some of them left open. Lights that were supposed to be off were turned on, and lights that were supposed to be on went out. Things left lying around would disappear, and things would appear when no one had any memory of putting them there. When any of these things happened, the old servants would say that the witch had visited the mansion, invisible, and was playing pranks."
