YMMV / Strong Poison

• Harsher in Hindsight: Lord Peter announces that he wants to prove Harriet's innocence absolutely, and that he'd rather see her hanged than have the public think she was a murderess who escaped justice. While he does secure her acquittal and identifies the real killer, later stories reveal that many in the public do still believe she was guilty and that he helped her pin the blame on someone else.
• Retroactive Recognition: In the BBC Radio adaptation, Nurse Booth is voiced by Joan Hickson. It's faintly incongruous to hear Miss Climpson as the investigative little old lady running rings round Miss Marple herself.
