Existence of Business Enemies

Exploration Stage: Antique Store
From: Augustine Capuchin
Description: Find out who came up with the witch prank. That person must have had a substantial motive. Is it a business rival? By the way, Mr. Delamode also deals in antique items. I think I saw something here that looks very similar to a shoehorn I bought from him some time ago. Could you please search for it with me?
Completed: It certainly looks a lot like something I purchased at Atelier Delamode. But, as Luis pointed out, most of the items that Mr. Delamode sells are clothes, and only a few elegant antique pieces. There seems to be no reason to go out of your way to scare off antique dealers.
