Ella O'Neill, the mother of revered American playwright Eugene O'Neill, is well known to have been a morphine addict, thanks in large part to her son's scathing depiction of her in his Pulitzer Prize-winning Long Day's Journey Into Night. Now, more than 50 years after O'Neill's play was first produced on stage, playwright Ann Harson takes another intimate look at Ella's life and addiction. Miles to Babylon is an imagined look at how Ella's admission to an austere convent finally liberated her from the grips of a dangerous habit that had plagued her for a quarter of a century.
