To Bertie, British theater producer and entrepreneur Bertie Alexander Meyer (1877-1967), Christie writes that she would be fine giving her novel "Ten Little Niggers" "a new lease of life. I don't know what production difficulties there are or if it 'dates' - Anyway talk it over with Edmund Cork [Christie's literary agent] ...." She signs, "Agatha." Christie is likely discussing the short-lived revival of her play which Meyer presesnted in September 1962 at St. Martin's Theatre. Christie's novel, "Ten Little Niggers" was published in 1939, with the U.S. edition being called "Ten Little Indians." Her first foray into adapting one of her novels into a play was with this book. It was eventually presented by Bertie Meyer, at the St. James Theater in London in 1943 with its original title. In 1944, the play opened on Broadway as, "Ten Little Indians," and for the 1945 American film adaptation, the title was again changed and became, "And Then There Were None." Bertie Meyer managed the German Theatre in London, became business manager for Charles Frohman, managed the Queen’s Theatre, and in 1913 became business manager of the Globe Theatre. He managed many theaters in London during his life, and in 1930, the Cambridge Theatre was built for him. In addition to these references, Christie mentions her agent, Edmund Cork, as the person to whom Meyer should speak. "He arranges all these things and knows far more about my affairs than I do."
