In Reichenbach, the political world still seems to be in order. There is exactly one social democratic vote in every election. Naturally, people think they know who this incorrigible person is. But when old Querdenke is buried, things get complicated. A letter is found in his estate that causes Mayor Singhammer a great deal of embarrassment. It is said to be the result of an affair between his mother and the recently deceased old man. And he threatens to reveal this secret posthumously if Singhammer doesn't parry. A letter to this effect has been deposited with the notary. The scandal can be avoided if a "red" vote is cast in every election from now on.
