is not clear when the errata were corrected for the audiobook. The book is inconsistent in its references to Bella Tanios' maiden name. There is an early reference to her as Bella Winter (see Chapter 1, page 8 "For Bella Winter, Emily Arundell's niece, had married a Greek").

"The Incident of the Dog's Ball" was published in Britain in September 2009 in John Curran's Agatha Christie's Secret Notebooks: Fifty Years of Mysteries in the Making. The short story was also published by The Strand Magazine in their tenth anniversary issue of the revived magazine in 2009.

Adaptations Television In 1996 the novel was adapted by Douglas Watkinson as part of the television series Agatha Christie's Poirot, starring David Suchet as Poirot. The adaptation made a number of changes to it, which included the following: The setting was changed from Berkshire to England's Lake District. Poirot visits the Arundell home before Emily dies, and not after; he does not use the pretence of buying it to examine the house. In addition, after learning of her
