Character Motive Mapping

Create a simple table listing each character, their expressed goals, and any contradictions you notice. Comparing entries often reveals hidden motives that drive the mystery forward.

  • Record each character’s stated motives to help identify contradictions later.
  • Compare Nancy’s observations with background lore to spot inconsistencies.
