Strange Curse

Exploration Stage: Ballet Academy
From: Adeline Svensson
Description: I'm trying to find out what happened to Juliette's best friend. If Charlotte disappeared without leaving any clues, then there must have been someone looking for her. There must be some newspaper article about this sensational case! But there's nothing in the old tabloids. Let's look some more. Maybe there will be some clues?
Completed: I found an envelope with a postcard in the basket of flowers Charlotte got me. It reads. So Charlotte didn't just disappear!
