Wish they had filmed the 4th ending
"The novelization was written by Michael McDowell based on the screenplay by Jonathan Lynn. There was also a children's adaptation entitled, Paramount Pictures Presents Clue: The Storybook written by Landis, Lynn, and Ann Matthews. Both adaptations were published in 1985, and differ from the movie in that they feature a fourth ending cut from the final film. In this ending, Wadsworth, after pretending to be dead, says that he killed Boddy as well as the other victims, and then reveals to the guests that he has poisoned them all so that there will be no witnesses and he will have committed the perfect crime. As he runs through the house to disable the phones and lock the doors, the chief detective – who had earlier been posing as an evangelist (Howard Hesseman) – returns, followed by the police, who disarm Wadsworth. Wadsworth then repeats the confession that he had given earlier to the guests, physically acting out each scene himself. When he arrives at the part about meeting Colonel Mustard at the door, he steps through the door, closes it, and locks it, leaving all the guests trapped inside. The police and guests escape through a window, while Wadsworth attempts to make a getaway in a police squad car, only to hear the growling of a Doberman Pinscher from the backseat."
