Hercule Poirot had to rely on his "little grey cells" to find the killers in Agatha Christie's novels, but the rest of us sometimes need some help. Enter a group of academics who say they've found a formula to identify the murderers in the legendary mystery author's books.
A group of experts, assembled by the British television channel Drama, say their formula can predict Christie's often twist endings, the Guardian reports. The formula takes into account such factors as which detective is doing the sleuthing, how the victim is killed and where the novel takes place.
