Example Input: passage: While the kids are away at college, Oliver eventually calms down and attempts to make peace with Barbara over an elegant dinner, but finally reaches his breaking point when Barbara serves him a paté which she implies was made from his dog. (It later turns out to be a bluff. The dog is still alive.) Oliver physically attacks Barbara, who flees into the attic. Oliver boards up the house to prevent Barbara from escaping so he can kill her, while Barbara loosens the chandelier to drop on Oliver to kill him. When their housekeeper Susan pays them an unexpected visit during the night, she senses something is terribly wrong and discreetly contacts Gavin for help. By the time Gavin arrives, Oliver and Barbara's quarrel has culminated in the two hanging dangerously from the insecure chandelier. During this time, Oliver admits to Barbara that despite their hardships, he always loved her, but Barbara does not respond. Before Gavin can come inside with a ladder, the chandelier's support cable snaps and sends them crashing violently to the floor. In his final breaths, Oliver reaches out to touch Barbara's shoulder, but Barbara uses her last ounce of strength to knock his hand away, firmly asserting her feelings for him even in death.
