Named ornaments

Exploration Stage: Compartment No.8
From: Detective
Description: We've learned a few interesting things about the man we think is the owner of the black cat, but we still haven't figured out the key to his identity. Hey, something is glowing under the seat! That's a money clip. Can you reach it?
Completed: This money clip has a four-leaf clover on it. This is a sign of good luck. And it has "R.D." engraved on the inside. That's my man, you found a good one! Do you know anyone with those initials?
