The first promotional photo has been unveiled for BBC One’s The Witness For The Prosecution.

Based on Agatha Christie’s 23-page short story, the new two-part drama is being adapted by writer Sarah Phelps (The Casual Vacancy) and the makers of last year’s hit And Then There Were None.

Filming began in Liverpool in August, with a cast led by Kim Cattrall (Sex and the City), Toby Jones (Tinker Tailor Soldier Spy), Andrea Riseborough (Oblivion).

The official synopsis reads: “A murder, brutal and bloodthirsty, has stained the plush carpets of a handsome London townhouse. The victim is the glamorous and rich Emily French (Kim Cattrall).

“All the evidence points to Leonard Vole (Billy Howle), a young chancer to whom the heiress left her vast fortune and who ruthlessly took her life. At least, this is the story that Emily’s dedicated housekeeper Janet Mackenzie (Monica Dolan) stands by in court.

“Leonard however, is adamant that his partner, the enigmatic chorus girl Romaine (Andrea Riseborough), can prove his innocence. Tasked with representing Leonard is his solicitor John Mayhew (Toby Jones) and King’s Counsel, Sir Charles Carter KC (David Haig).”

The cast also includes David Haig (The Thick Of It), Billy Howle (Cider with Rosie) and Monica Dolan (The Casual Vacancy).

BBC One’s adaptation of And Then There Were None aired last Christmas, starring Aidan Turner (Poldark) and Sam Neill (Jurassic Park).
