Third Question

Exploration Stage: Post Office
From: Mr. Black
Description: I'm inclined to think you're telling the truth and that you really are the Mystery Solver. But I still have questions. So, you sent the signal using the slot machines. But how did it overcome the fog? For a signal to reach the Upper City, there must be a receiver...
Completed: So this spotlight received the signal from your part of the City and transmitted it to us? There's the Collector's mark on it! No wonder the signal was able to overcome the fog.
