S3 Episode 10 - Dame Agatha's Grudges

Sophie is joined by psychotherapist and fellow Agatha Christie
superfan Helen Acton to discuss grudges — valid/reasonable and
invalid/unreasonable — in the novels of Agatha Christie, the Queen
of Crime. Also in this episode: the beauty of three-layered puzzle
solutions, the Insufficient Poirot Content grudge some fans have
about novels like Cat Among the Pigeons and After the Funeral, and
Sophie reveals her grudge-related theory about why Murder on the
Orient Express and And Then There Were None are Agatha's two most
popular and beloved books.
