Case GF-005 · The Gaslight Files
The Seventh Post
This page contains no spoilers. Nothing here names who did it or how.
1 Before you open the envelope
The solution only feels good if you commit first. Make sure your team has:
- Answered all three objectives on the Case Closure Form:
- WHEN did Matthias Crewe die, and what did the police get wrong?
- WHO was with him, and what was staged afterwards?
- WHO killed him, HOW and WHY?
- Written down the three exhibits that prove your answer best.
- Given a reason, from a document, for ruling out every other person of interest.
- Agreed as a team. No changing answers once the envelope is open.
2 Not sure yet?
Use the hint cards before you give up on the case. Each step has three cards: A is a gentle nudge, B tells you where to look, and C gives the answer to that step only. Turn over one card at a time. The checkpoint cards confirm you are on track without naming anyone.
The hints are in their own file in your download, so print them only if you want them.
3 The reveal
Open the solution file from your download. It is a separate PDF so nobody sees it by accident. Read it in order:
- The closing letter. The investigators tell you how the file was finally closed.
- The answer key. Check your Case Closure Form against it, one objective at a time.
- The deduction chain. Every step of the proof, with the exhibits that carry it.
- What really happened. The full timeline, start to finish.
