Flugten Fra Vridsløselille [The Escape From Vridslöselille]

Your friend is in jail… again! and this time it has long prospects for him to come out and see the light of day. He has asked you to visit because he has found a letter from the former prisoner that suggests he has created an escape route to freedom. Unfortunately, the letter is written in a rather cryptic style, so it takes more than one person to solve the mystery. Since neither of you has pure flour in the bag, you immediately agree to the idea. There is a rumor about the previous prisoner who says that there was always a lot of noise from his cell and that the electricity always came and went like during a violent storm - but the guards couldn't find anything...
