Alarming Signal

Exploration Stage: Atelier Delamode
From: Anna Weber
Description: I know that an unusual event occurred in the Atelier, although I didn't see anything. But I heard it! Fabien doesn't receive customers in the evenings, and although it was already late, someone was persistently ringing the bell. It's very loud, try ringing it.
Completed: This table bell makes a shrill sound. Fabien uses this one on purpose so he can always hear it and rush to his clients. The ringing distracted me from my work, and I wondered who it could be, as it was much too late to receive clients.
