set in a medieval monestery where you have to go through Jonathon Ross' cell and the library for clues about who killed him, with suspect cards and you ask other players questions like "Jim, have you eliminated any Fransiscan novices?" "Laura, have you elimated any Benidictine fathers?"...
With a semiotic blind Andrew Sachs pottering about in the background all the time.
You get sent into penance for getting too exctied and spilling communion wine.
pretty post modern.
