The players sit in a circle facing inwards. One player, the
detective, is taken away where he can not see or hear the
others. One of the players in the circle is designated as the
murderer. Put one piece of paper in a bowl for each player and
mark one with an \'X\'. Have someone take the bowl around and
have each player take one, look at it and then replace it in the
bowl. The player with the X is the murderer. The players decide
a secret signal. This could be a pointing finger, a wink, a
twitch of the nose etc. The detective is then returned to the
circle where he must guess the identity of the murderer before
the murderer kills everyone by using the secret signal. If any
of the players detects the signal coming from the murderer he
must \"die\" in some dramatic fashion. The detective only has a
limited number of guesses in which to guess the identity of the
murderer. Three guesses is standard. If the detective fails to
guess in time, the murderer takes his place and play continues
anew.
