This is another Hercule Poirot Mystery first published in 1926.
The story was narrated by Dr Sheppard in the book. Dr Sheppard was a doctor in a small village of King’s Abbot. He was the attending doctor of Mrs Ferrars and the story started with Mrs Ferrars had an overdose of a drug for sleeplessness. Was it suicide or accidental overdose?
Roger Ackroyd, a rich man in the village, gotten on well with Mrs Ferrars. The village speculated that both would get married since their spouses had died. But before this could happen, Roger Ackroyd was stabbed to death in his house.
Hercule Poirot had already retired and he chose to live in the village when all these were happening. The story continued with Poirot investigating the murder of Roger Ackroyd. Dr Sheppard was assisting Poirot in his work.
The execution of the murder was clever. I could not have known how it could happen and the motive for the murder. The question one could ask was whether the deaths of Mrs Ferrars and Roger Ackroyd were connected in any way. The end was unexpected.
