GROPING ABOUT

Exploration Stage: Heirs' Villa
From: Mr. Black
Description: I have a theory that there’s something covering only the keyhole and not the entire room. I’m going to remove the obstacle with my pocket manipulator... Ugh, I think I dropped it. Please find it.
Completed: Thanks. The manipulator is intact, and I’ll quickly remove whatever prevents me from looking through the keyhole. The strange thing is... something won’t let it through. But there doesn’t seem to be anything... Fog take me, I’ll break down that door!
