This is a Hercule Poirot Mystery first published in 1952.
Mrs McGinty went to homes to help clean the houses in a small village of Broadhinny. She was hacked to death on her head and a suspect James Bentley was convicted of her murder. James Bentley was at that time lodging with Mrs McGinty’s home. Evidences pointed towards him as the murderer. Lucky for him, the investigating police Superintendent Spence felt something was not quite right. Spence enlisted the help of the famous Belgian private detective Hercule Poirot to get to the bottom of it.
How would one start when the police had not been able to get headways with evidences on hand? Could Poirot find fresh evidences to prove the innocence of the convicted killer? The problem was compounded with the fact that James Bentley could not defend himself and was resigned to the guilty verdict.
For Hercule Poirot, he had to dig into the family histories of several individuals in the village to piece a motive for the murder of Mrs McGinty. That took a bit of time in the story. In the end, the key to solving the murder was indeed to look into the family backgrounds of some individuals staying in the small village. Who then killed Mrs McGinty? Let Hercule Poirot tells you.
