What Happens, Part by Part (Contains Spoilers)
An old case
Carla Lemarchant is about to marry, but she fears that her mother's guilt will haunt her. Before her death, Caroline wrote Carla a letter saying she was innocent. Poirot agrees to look at the case. He knows that the facts were never in doubt: Amyas died from coniine, a poison made from hemlock, in a glass of beer, and Caroline had taken the poison.
Five people
Poirot finds the five people present at the time, like the five little pigs of the nursery rhyme. They are Philip Blake, Amyas's oldest friend; Philip's brother Meredith, who brewed herbal medicines; Elsa Greer, now a wealthy lady and Amyas's former lover; Miss Williams, the family governess; and Angela Warren, Caroline's younger half-sister, who was scarred by Caroline in a fit of temper when she was a baby.
Five accounts
Poirot interviews each one and then asks them to write down their memories. Their accounts disagree in small but telling ways. Philip hated Caroline; Elsa was confident Amyas would leave his wife; Miss Williams saw Caroline wipe fingerprints from the beer bottle; Angela had once put a bitter herb into Amyas's beer as a prank.
Putting it together
Poirot studies what each witness saw and why they saw it that way. He notes that Caroline never really defended herself at the trial, as if she were protecting someone. He also looks at the painting Amyas was finishing of Elsa, which shows her expression on the final day. Slowly, a new picture of that afternoon appears.
The truth
Poirot reveals that Elsa killed Amyas. She overheard him say he would send her away once the painting was done, so she poisoned his beer. Caroline found Amyas dead and believed that Angela had done it, perhaps as another prank gone wrong. To protect her sister, she wiped the bottle and accepted the blame. Elsa, who won nothing, is left empty, and Carla finally knows her mother's innocence.
5 Key Takeaways
- Old crimes can still be solved with careful questions.
- Each witness sees events through their own feelings.
- Silence can be a form of protection.
- Love and guilt can lead people to sacrifice themselves.
- Psychology can be as revealing as physical clues.
Ideas Worth Remembering
