- Worth noticing
- The investigation treats each location's full printed name, including details after the comma, as part of the evidence.
Field notes
The investigation separates evidence into suspects, locations, and chronology rather than presenting a single linear clue path. Its location rules are unusually exact: the full printed name, including area or building details after a comma, counts as the entry. The answer desk accepts canonical selections and offers typo suggestions, while the archive sketches a series structure around later city cases that are currently sealed.
