Scooby-Doo

There is only one point of interest in our village: it's an old gothic castle, where, according to legend, is the tomb of Dracula, guarded by Van Helsing himself! But we know that vampires do not exist, and now there is a historical museum in this castle. However, there have been no visitors there for a month, because they run out of there in terror, telling scary stories about ghosts and exhibits come to life. We invited the "Mystery" team to investigate this case, but even Scooby-Doo himself, with his tail between his legs, ran away from there, without finishing it. He left your phone number saying that you would handle this case better. I hope you don't believe in mysticism and will be able to find out who is scaring people there and why they need to do it.
