Crimson earrings

Exploration Stage: City Hall
From: Valerie
Description: You'll never guess where I hid Lucrezia's earrings - in City Hall. Martha once said that they act as a love potion, making a man's heart beat faster when he sees a woman wearing them. Lucrezia wore the earrings the night her brother Cesare killed her husband, Giovanni.
Completed: Here's the second trinket, which I'll put in the vault. We need three more pieces. While you visited Valerie I consulted Martha. She's interested in your search and wants to use her crystal ball to pinpoint the location of the other pieces.
