Kara Helgren has previously worked for the city of Salem, Massachusetts as a tour guide, leading visitors through the ominously-named Witch House. According to Helgren tourist expectations veered toward the lurid and macabre. Visitors expected tales of ghosts, black magic, and torture. Helgren (whose thesis was about the witch trials) gave them none of that. Instead, she crushed their dreams and broke their hearts with a bunch of historical accuracy.
