Sarah Phelps on The Pale Horse, We Will Walk, Kamau Brathwaite and George Steiner remembered

As she completes her quintet of Agatha Christie adaptations with The Pale Horse, screenwriter Sarah Phelps discusses why Christie’s supernatural murder mystery attracted her attention when she was looking for a fifth work by the Queen of Crime to turn into television drama.We Will Walk - Art and Resistance in the American South is an exhibition of sculptures, paintings and quilts made by African American artists from Alabama and the surrounding southern states, made mainly during the Civil Rights movement of the '50s and '60s. Art critic Asana Greenstreet reviews the show, which is at Turner Contemporary in Margate and includes many works not seen before in the UK.This week Edward Kamau Brathwaite, the great poet of the Caribbean, died. Brathwaite realised the potential of West Indian vernacular, the beauty of its rhythms and vocabulary, as the language to speak of the Caribbean experience – surf, hurricanes, rum and calypso, the memory of Africa and the history of slavery. The poet Fred D’Aguiar pays tribute. Following the announcement of the death of the writer, academic and cultural critic George Steiner, the writer Robert McCrum - his editor at the Observer newspaper, and the publishing house Faber & Faber – pays tribute to Steiner’s life, work and his legacy as a public intellectual.Presenter Chrystal Genesis Producer Jerome Weatherald
