Five Little Pigs (1942)

Sixteen years after Caroline Crale was convicted of killing her husband, her daughter asks Poirot to examine the case again. The evidence comes largely through people who have lived with their own versions of the same afternoon. Christie makes differences in emphasis and remembered feeling as important as an overlooked fact. This is a particularly direct choice for readers interested in listening as detection, with the daughter’s future affected by a judgement made before she could understand it.
