The Puppeteer's Secret

You are journalists. While other publishers are just churning out news about a new maniac and people disappearing, and the police are inactive, you decided to take matters into your own hands. For many months you have been conducting your own investigation on this matter and were almost sure that all the disappearances are connected, but things did not add up... Until one point. You receive a video in which a girl, who introduced herself as Alice, detailed what had been happening to her over a several weeks. The puzzle came together. All that remained was to verify this information. Having noted down the address mentioned by the girl, you set off to search for your own scoop.
