Mystical

Mysterium.  A 'post Cluedo' game in which the ghost of the victim is trying to guide all the other players (as mystics) to idetify the perpetrator, location and weapon.

Unfortunately, it's a lot more opaque than Col.Mustard, in the library with the dagger, and the ghost can only communicate using a limited hand of pictures that resemble the target images the ghost if trying to point at in much the same way that a fish resembles Venezuela.

Good fun though, and one mystic did indeed correctly identify the toymaker, in the piano room, with the secateurs.
