Unhappily, George is now confined to his bed with heart problems. There is a heat wave, and Ellen is spending most her time caring for him. Georges doctor is their old friend Ranney, with whom George thinks his wife is having an affair. In response, Ranney suggests George may need psychological help. After Ellen tells her bedridden husband she dreams of having children, he becomes angry. Meanwhile, George has written a letter to the District Attorney in which he claims his wife and best friend are killing him with overdoses of medicine for his heart.A little neighbor boy dressed as a movie cowboy and wearing cap pistols Bradley Mora befriends the childless Ellen, who gives him cookies. He hands her a toy fake television set and asks Ellen to give it to George, which she does whilst serving her husband lunch in bed. He tells her an unsettling story about how, as a child, he had beaten a neighbor boy with a rake until he drew blood. Thinking the thick letter has something to do with insurance, Ellen gives it to the postman Irving Bacon, who sees George in the upstairs bedroom window. When Ellen rushes up to find out why he has gotten out of bed, George lets her know what the letter says and who it is addressed to. George pulls a gun and is about to kill her when he drops dead on the bed. In her narration she describes Georges death as one of those awful dreams. ........
