What book is A Haunting in Venice based on, who’s the killer in the new Poirot movie and is the ending different to the Agatha Christie novel?

You might be tempted to read the novel A Haunting in Venice is based on but there are major changes.

If you’ve been tempted to find out how to watch Shetland thanks to the show’s suspenseful stories and atmospheric setting then A Haunting in Venice captures a similar sense of eeriness and mystery. This is the third in Kenneth Branagh’s movie adaptations of Agatha Christie’s Poirot novels and is set in Venice on Halloween night. Legendary Belgian detective Hercule Poirot finds himself at the centre of a new case as a storm prevents escape from a palazzo owned by retired opera singer Rowena Drake. One murder at the house starts it all and Poirot is determined rationality should prevail in a world of superstition.
