    §3. Register the three pieces of evidence#

    Click the scattered objects to register the messy-person clue. Inspect the black hair on the floor, then the crowbar near the entry area. Each item contributes a separate evidence entry.

    The crowbar description associates the tool with blacksmith work. Combine that with the messy room and black hair; a single clue alone leaves too many possible suspects.

    The Friend profile lists blacksmith work and a messy personality.
