Page "Clue (film)" Paragraph 14

Miss Scarlet is the culprit in the first ending.

Having used her former call girl Yvette to murder Mr. Boddy and the cook, she herself killed Yvette and the others to keep her true business of " secrets ( extortion )" safe, planning on using the information learned tonight for her own benefit.

While Miss Scarlet holds the group at gunpoint with the revolver, Wadsworth tries to tell her that she used up all the bullets in the gun but she tells him she still has one and threatens to kill him.

Wadsworth reveals himself to be an undercover FBI agent and arrests Miss Scarlet as police secure the house.

Finally, insisting to Miss Scarlet the revolver is empty, Wadsworth accidentally fires the last bullet into the air, hitting another chandelier, and causing it to crash closely behind Colonel Mustard.
