Oh, I love Agatha Christie. Her stories are so fun, even if the mysteries are usually easy to solve. Five Little Pigs is one of the Hercule Poirot mysteries; he flies solo on this one. The book was originally called Murder in Retrospect, not sure why it was changed, but it also makes sense.
Amyas Crale was murdered, and his wife Caroline was executed for the crime. Sixteen years later, their daughter returns to England (after being raised in Canada) to try to clear her mother’s name. Her mom wrote a letter just before her execution saying that she didn’t do it. However, she raised almost no defense at her trial, and everyone figures she did that, because she did it.
The daughter enlists Poirot to re-investigate the crime, so he goes back to scene of the crime and speaks to everyone who was involved. Our Five Piggies are: Phillip Blake, a stockbroker (“went to market”); Meredith Blake, Philip’s brother, a reclusive former amateur herbalist (“stayed at home”); Lady Dittisham (nee Elsa Greer), Amyas’s lover (“had roast beef”); Cecilia Williams, the governess to the Crale’s child (“had none”); and Angela Warren, an archaeologist and Caroline’s sister (“cried ‘wee wee wee’ all the way home”). Each had motive, means and opportunity. But so did Caroline.
Poirot interviews everyone, and has each write out their memories of the events leading up to the murder. He also talks to the police and lawyers involved in the case, and in the end, he figures it out, and does the whole “gather everyone together & reveal the real killer” bit. For me, that never gets old. Highly enjoyable, like all of Christie’s books.
