eyes of a liar

Exploration Stage: Red Rose Cafe
From: Cardsharp
Description: Everyone is working so hard to help me. I'll remember this until the day I die! I know a few card tricks, so I'm in... for example, Master F. used to refill his pipe with tobacco several times during the shuffle. He had a mirrored tobacco container! Let's find out.
Completed: Oh! It's so polished, isn't it? I used this instead of a mirror. The crook was checking my cards in the mirror.
