negative influence

Exploration Stage: Compartment No.8
From: Detective
Description: Buddy, I think I may have figured out who the guy was in compartment 8. But the train is messing with my head. The guide told me this would happen... but yes, an artifact might be able to protect my eyes from the negative energy of the fog express. Can you lend it to me?
Completed: While the artifact is paying off the negative energy of the Fog Express, let's check out what we've collected so far. Lottery tickets, poker charms, and a money clip with the initials "R.D." on it...Hey, Mr. R.D., who are you? Wait a minute... are you Roger Double Deal? Yes, I'm sure of it! I've got the research papers right here, too!
