What do you know! Here is Harper Lee, usually referred to as "the reclusive Harper Lee," attending a luncheon for high-school essayists at the University of Alabama. She talked a bit to Ginia Bellafante, a reporter at the New York Times.
I think the seriousness and respect with which she explored a child's moral and creative imagination gave real freedom to all juvenile realistic fiction in the last half of the last century.
Registration is necessary to read the New York Times. Thank you to Read Roger for pointing out the article.
