Our month-long salute to mystery writing legends continues with the queen of crime herself - Agatha Christie. She wrote over sixty novels, dozens of short stories, and created two of the genre's most beloved sleuths - Hercule Poirot, the fastidious and brilliant Belgian detective, and Miss Marple, the kindly amateur investigator. We'll hear four of Dame Agatha's tales recreated for radio: "The Murder of Roger Ackroyd" with Orson Welles as Poirot from The Campbell Playhouse (originally aired on CBS on November 12, 1939); "The Tragedy of Marsdon Manner" from Murder Clinic (originally aired on Mutual on October 6, 1942); and "The ABC Murders" and "Where There's a Will" from Suspense (originally aired on CBS on May 18, 1943 and February 24, 1949).
