How do everyday struggles relate to the bigger tragedies of life? And what are their respective roles in fiction? We’ll talk with novelist Andre Dubus, III whose new book “The Garden of Last Days” (W. W. Norton, 2009) explores the lives of such struggling characters including one who’s preparing for his role in the 9/11 attacks. We’ll visit the Dallas Museum of Art for a conversation with Irish artist Willie Doherty in tonight’s Art and Seek segment. Twice nominated for the Turner Prize, Doherty’s solo exhibition “Requisite Distance” is on view at the Dallas Museum of Art through August 30th.
