Lilac Diamonds

Exploration Stage: Castle Gate
From: Detective
Description: All the victims describe the lost jewellery as massive, made of gold, and inlayed with rare lilac diamonds. The thief must want them for the gems. Valerie had such a bracelet, but it made me feel uncomfortable when she was wearing it. Let’s start our search with the bracelet.
Completed: Whoever the thief is, their trick didn’t work, and you managed to find the bracelet. You’re a real ace, buddy! It’s unpleasant to hold the bracelet in my hands... What magic is this?
