Silent Messenger

Exploration Stage: Mistress’ Bedroom
From: Martha
Description: Judging by Bartholomew’s recollections, he wanted to take advantage of the Mistress’s lively ball and thwart some of her plans, which are thus far unknown to me. But now a new image is being revealed to me, and it’s associated with Bartholomew himself: it’s a small metal fish. Could you look for it?
Completed: I think I know what this fish is... You’ve found a message container! These hollow souvenir figurines were used to send secret messages. Bartholomew wanted to use it to contact someone. The note is still inside! Let’s read it.
