A Mad Tea Party

Exploration Stage: Atelier Delamode
From: Mr. Black
Description: Don't aggravate your guilt, Delamode. How many more buttons did the sewer maniac supposedly steal from you? Two more are missing? Deduction tells me that we need to look in the most unexpected places. Let's examine the tea atable.
Completed: Look, this embroidered napkin also enjoys having a ruby button on it. Mr. Couturier, you've chosen a very bad tactic for confusing the trail. Bear in mind that I can qualify your actions as a mockery of the City government.
