From Introduction: This is a tricky little investigation designed for 2+ characters. The specific setting can be anywhere in the continental US, so the GM is encouraged to create detailed maps and other props to assist players in visualizing the adventure. ADVENTURE HOOKS: BPI: If the characters are agents of the BPI or Sedgewick Society investigators, they may be called in due to the strange nature of the deaths. Hired: The characters may have been brought in by McCloughlin Testing Laboratories, the police, or the family of one of the victims. Curiosity: The characters may read details about the sightings and decide to investigate.
