Book excerpt: In this widely praised follow-up to her National Book Award-winning first volume of memoirs, An Unfinished Woman, the legendary playwright Lillian Hellman looks back at some of the people who, wittingly or unwittingly, exerted profound influence on her development as a woman and a writer. The portraits include Hellman's recollection of a lifelong friendship that began in childhood, reminiscences that formed the basis of the Academy Award-winning film Julia.
