Professor Kleine, as an unusual final exam, has his students come to his house and try to solve a murder he's set up and then write descriptively about it later. When the students begin searching the house, the clues look all too real and somebody remember that the Prof's wife hasn't been seen in some time. Then, when the students themselves, started dying off, well, this may just turn out to be a final exam. Except who is the murderer? And who is really dead?
