I joined the Agatha Christie challenge and finished my first Agatha book all in the same day - LOL. This is the first book I have read of hers and it definitely won't be my last!! And no, I didn't figure out who did it before the ending.
After I finished the book, I went back and discovered all the little clues that I had missed. I guess I was looking at the big picture and not the small stuff.
In the famous words of Hercule Poirot, "Beware! Peril to the detective who says: 'It is so small - it does not matter. It will not agree. I will forget it.' That way lies confusion. Everything matters."
The Mysterious Affair at Styles is narrated by Arthur Hastings who is recouperating as a guest of John Cavendish at Styles Court. The country home is owned by John's step-mother, Emily Inglethorpe. She has considerable wealth and recently married a man 20 years her junior. When Emily is poisoned by strychnine, Hastings recruits his old pal, Hercule Poirot - a retired detective, to aid in the investigation.
This is the first book that introduces Hastings and Poirot. She wrote this in 1920 and Poirot's last case was published in 1975, Curtain. However, according to a couple of biographies I have read, she wrote this book back in the 1930's.
