She’s still widely regarded as one of the greatest mystery writers ever, but coming up on what would be her 125th birthday, a group of academics has managed to create an algorithm that can accurately predict which character will turn out to be the killer in an Agatha Christie novel.
A panel of academics, including data analysts and researchers from Queen’s University in Belfast, analyzed 27 of the 83 novels published by Agatha Christie during her lifetime and discovered that the story’s location, modes of transport, and the nature of the victim’s death were all important clues to solving the mystery.
It was also discovered that how the culprit was introduced served as a key clue to the mystery. When the killer was a female, Christie tended to use a more negative sentiment when introducing the character. But when the killer was male, the word patterns used to mention or address the character were more neutral or positive.
