Is Hercule Poirot the world's greatest detective? Dr Mark Aldridge certainly think so, as he explores in his latest book Poirot: The Greatest Detective In The World. Mark is joined on the podcast for the Noirwich 2020 finale by crime writer Sophie Hannah, author of the Poirot continuation novels including the new The Killings at Kingfisher Hill. Their conversation takes in everything a Poirot fan could want, from discussing his best - and most unusual - cases, and why Agatha Christie's detective continues to be popular a century after his introduction.
