Expensive interior

Exploration Stage: Traveling Circus
From: Fabien Delamode
Description: It was definitely a member of the circus who stole my brooch at the cabaret. But I need proof to make Director Black believe that. Let's look for something expensive. I can't have sold everything I stole, can I? Gold, diamonds, velvet...anything like that?
Completed: It is true that these flags are made of velvet, but they are of very poor quality. And the finish is cheap. But they are relatively expensive for circus decorations. I don't believe that such money is available to this circus, but it is not convincing evidence to offer to Director Black.
