In order to get ready for our new campaign, we figured we should maybe try out the rules again as it has been a long time since we last played this game. Also this game was a way of introducing a new player to the game.
In the trail of clues scenario four plot points are placed 12" in from the corners, then each of the leagues are deployed within 12" of a corner (more than 6" away from a plot point) The major plot point is only placed on the table when one of the leagues has completed a minor plot point.
