She's back, with that infectious laugh of hers, and we couldn't be more delighted. Hildur Guðnadóttir is one of my very favourite composers of film music, and she joins me to discuss Kenneth Branagh's latest take on Agatha Christie, A Haunting In Venice. Darker and more claustrophobic than the previous two Poirot mysteries he directed and starred in, A Haunting In Venice sees the Belgian detective investigate a murder while attending a Halloween seance at a palazzo in the floating city.
