Agatha Christie Before marrying and starting a family in London, she had served in a Devon hospital during the First World War, tending to troops coming back from the trenches. She was initially an unsuccessful writer with six consecutive rejections, but this changed when "The Mysterious Affair at Styles", featuring Hercule Poirot, was published in 1920. During the Second World War, she worked as a pharmacy assistant at University College Hospital, London, acquiring a good knowledge of poisons which feature in many of her novels. "Guinness World Records" lists Christie as the best-selling novelist of all time. Her novels have sold roughly
Hercule Poirot as he had been to her: a great detective, a remarkable man, if, perhaps, just now and then, a little irritating. I think back to Poirot’s last words in the scene before he dies. That second ‘Cher ami’ was for someone other than Hastings. It was for my dear, dear friend Poirot. I was saying goodbye to him as well — and I felt it with all my heart. The writers of the "Binge!" article of "Entertainment Weekly" Issue #1343–44 (26 December 2014 – 3 January 2015) picked Suchet as "Best Poirot" in the "Hercule Poirot & Miss Marple" timeline.
