Escape from the Poltergeist

Despite the fact that poltergeists quite harmless creatures, they are also there may be some trouble. With that just ran into a hero of our game, when I woke up this morning and found that his room is a mess, and the front door was locked. Surely this is a poltergeist so decided to make a joke on him. Well, he did not return the key - it is exactly so will have to find out for yourself.
