Why did Helen duncan get accused of being a witch?

Helen Duncan was accused of being a witch due to her practice as a medium and her ability to allegedly communicate with the dead. In 1944, she conducted séances that attracted attention, but her claims were met with skepticism by authorities. Her most notable accusation arose when she was charged under the Witchcraft Act of 1735, primarily because her séance revealed information about a naval disaster that was not publicly known, leading to concerns about national security. This combination of her spiritualist activities and the sensitive information she purportedly disclosed fueled the witchcraft allegations against her.
