After Alice had died, Doctor Jeffreys, left David alone in his bed. He knocked him out with sleeping pills so he would sleep easier. When he came the next morning he “smelt gas in the house”, that's when he ran up stairs to “find that the gas had been turned on” and it “had killed David”(Page 13, The Small Assassin book). In the movie, David died at the bottom of the stairs not in the his room. Their bedroom is actually where Alice was found dead by Doctor Jefferys in the movie. This is one of the big differences between the story and the film because it is the exact polar opposite from what was shown in both the variations of the story. A good number of Ray Bradbury's works were adapted into films, a lot of them also contrasted their book counterpart like in this book, The Small Assassin. The book and the Film are two very different versions of the same story. I found the film was very different in many aspects. It lack narrative where the book did not. This is what I think made the Book, The Small Assassin, different from its movie
