First look at Harry Potter star Rupert Grint in new BBC Agatha Christie drama The ABC Murders

The Harry Potter star plays Inspector Crome in the new TV adaptation, a detective of rather limited ability who takes some persuading before finally respecting detective Hercule Poirot’s methods.

The three-part mystery will air this Christmas on BBC1, with US star John Malkovich playing the legendary detective.

The scripts for The ABC Murders have been written by Sarah Phelps, who is nothing if not bold in her adaptations of Christie – last Easter’s Ordeal by Innocence starring Bill Nighy changed the identity of the book’s murderer.

Also starring in the BBC1 drama is Tara Fitzgerald, Andrew Buchan and Jack Farthing, the actor best known for playing Poldark villain George Warleggan.

The story is set in the 1930s at a time “when the nation is dangerously divided and suspicion and hatred are on the rise,” according to the BBC.
