Secret Messenger

Exploration Stage: Bedroom
From: Martha
Description: Bartholomew's recollection is that he was trying to foil some of her plans by reversing the bustle of the fat floor held by the mistress. Now a new image comes to mind. This time it is a memory of Bartholomew himself. I see a small iron fish. Can you try to find it?
Completed: This must be... a message box! Figurines like this were often used to convey secret messages. It looks like Bartholomew was trying to contact someone with it. The note is still inside! Let's read it.
