Star of ‘The Ipcress File’ and ‘Bohemian Rhapsody’ Lucy Boynton joins a cast of famous faces in Hugh Laurie’s adaptation of Agatha Christie’s captivating murder-mystery ‘Why Didn’t They Ask Evans?’. The three-part series follows a vicar’s son and his adventurous friend, socialite Lady Frances ‘Frankie’ Derwent (Lucy Boynton) as they dig deep into a murder. But their amateur sleuthing brings no end of trouble their way. Lucy joins us in the studio to tell us why she can’t say no to an Agatha Christie saga, what it was like to be directed by Hugh Laurie and starring alongside Emma Thompson and Jim Broadbent.
