"As an Agatha Christie superfan, this job is a dream come true," writer Phoebe Eclair-Powell says. "I am eternally grateful to James Prichard and Agatha Christie Limited for having me on board. With the excellent teams at Lookout Point and BritBox, who are clear Christie fans too, it’s a perfect combination. Christie's detective duo are witty, sharp and raring to solve lots and lots of murders whilst asking if they should really be more than just Partners in Crime…To bring Tommy and Tuppence into the twenty-first century is truly an honour."
