Caroline Newcliffe was a plot twist villainess in the movie The Beast Must Die.
She was portrayed by Marlene Clark.
Caroline Newcliffe was the wife of eccentric millionaire hunter, Tom Newcliffe, who was on the hunt for a werewolf and suspected one of his guests of being the culprit. The guests were subjected to odd tests by Tom, with one of them involving placing a silver bullet in their mouths (since silver is deadly to werewolves). Even Caroline is part of this test; being the last to receive her bullet.
Once Caroline was about to place the bullet in her mouth, her right hand was covered with hair and her nails had become long, black claws. At that moment, Caroline turned heel and transformed into a werewolf, much to the shock and horror of the rest of the group. After her transformation, the evil Caroline lunged after Tom, who shot his wife to death. It was revealed that Caroline contracted the werewolf disease from her dog, who was killed by the actual werewolf.
