Helen Baxendale leads the cast in Channel 5's third Agatha Christie feature-length drama, Agatha and the Midnight Murders.
Set during World War II in the 1940s, the drama takes place over the course of one evening, when a debt-ridden Agatha (Baxendale) and her companion Travis, a roguish grifter, get caught up in the middle of an air raid while attempting to sell one of Agatha's unpublished manuscripts under the table.
Here's everything you need to know about the cast and characters of Agatha and the Midnight Murders.
Helen Baxendale plays Agatha Christie
Who is Agatha Christie? The famous crime writer, who in the 1940s is in her fifties and well known across the globe. She was the creator of Miss Marple and of Hercule Poirot, the Belgian detective. At the start of Agatha and the Midnight Murders, Agatha has decided to settle her debts by killing off Poirot and selling the unpublished manuscript to a wealthy private buyer.
"When Agatha talks about her perilous financial situation, that is all true, so that's something that is again a very important starting point for this story," screenwriter Tom Dalton exclusively told RadioTimes.com. "She was in financial difficulty because... the Americans stopped paying royalties at the beginning of the year, and this is a big deal if you think about it... To suddenly have that revenue stream shut off was really quite serious."
