Actor Hugh Fraser, who played Captain Hastings opposite David Suchet in Poirot, has turned to crime writing and will be a guest at Books by the Beach later this year.
But his debut novel Harm is much harder-edged than anything Agatha Christie ever wrote.
It tells the story of a female assassin involved with Mexican drug cartels and, before then, growing up rough in 1950s Notting Hill.
“I’m thrilled we’ve got such a talented actor turned talented writer coming to Scarborough,” Books By The Beach co-director Heather French said.
Co-director Peter Guttridge said: “I first became aware of Hugh Fraser when he was virtually unrecognisable in the arthouse period film The Draughtsman’s Contract in wig and make-up – he was very sinister. So I’ve always been aware that behind the good-hearted Captain Hastings a dark side might lurk. His novel demonstrates that.’
Hugh Fraser is not the only crime-writer visiting Scarborough, of course.
Agatha Raisin creator, MC Beaton is also a guest at the festival.
Melvyn Bragg will be at Scarborough Spa on Friday April 15.
The festival runs from Wednesday April 13 to Sunday April 17.
