Wrong Address

Exploration Stage: Historical Museum
From: Mr. Black
Description: Mrs. Hartley found the ill-fated device in a house that had been brought from somewhere else by the fog. She says she also took the address plaque with her. Find it, and we’ll find out whose chronometer it was.
Completed: I can’t see the house number or the street name. Did the fog erase them? Mrs. Hartley claimed it was valuable, though. That’s a sample of the fog’s effect on everyday objects? Oh, those scientists.
