Final answer:
Roald Dahl's adult novels include 'My Uncle Oswald,' but the provided passage does not come from his adult novels.
Step-by-step explanation:
The question asks about the title of an adult novel by Roald Dahl. Roald Dahl is well known for his children's literature, but he also wrote for adults. My Uncle Oswald is an example of an adult novel by Dahl. The passage provided, however, is from a short story and not from one of Dahl's adult novels. It is important to distinguish between his works for children, adult novels, and adult short stories.
