- Crowning Moment of Funny: When Poirot interviews the policeman who led the investigation into Amyas's murder, the policeman spends a fair bit of time railing against the painting he was working on, a near-nude portrait of the very attractive and young Elsa Greer. Poirot notes that for all his disgust, the policeman appears to have a very clear and detailed recollection of the work in question.
Amyas and Angela had a first-class row, I know, and the rest of us rather welcomed it. It avoided other difficulties. Angela rushed off to bed with a final vituperative outburst. She said A, she’d pay him out. B, she wished he were dead. C, she hoped he’d die of leprosy, it would serve him right. D, she wished a sausage would stick to his nose, like in the fairy story, and never come off. When she’d gone we all laughed, we couldn’t help it, it was such a funny mixture.
- Amyas and Angela have an argument which she caps off with a truly hilarious insult.
- Moral Event Horizon: Subverted. The murder of Amyas and framing of Caroline at first appears to be this, but by the end of the story, the murderer's empty, joyless life and hopeless outlook come across as quite pitiable, a fact which is lampshaded by Poirot himself.
