Pulitzer Prize-winning author William Styron (“The Confessions of Nat Turner,” “Sophie’s Choice”), 75, was released Monday from a Virginia hospital where he spent the night after complaining he was feeling tired after staying up late at a Saturday speaking engagement, reports the Associated Press. “He just overdid it and we were concerned. We just wanted to be careful,” said his son, Thomas Styron. The Saturday event was honoring Styron’s life’s work. Earlier this year, Styron was reportedly hospitalized for a month, being treated for depression and pneumonia.
