Over the course of his career, actor Michael K. Williams says he's learned to separate himself from his characters (like Omar on 'The Wire'). He also co-starred in 'Boardwalk Empire,' and is now in HBO's 'The Night Of.' Critic at-large John Powers reviews a new dystopian novel. Also we hear from soul singer Sharon Jones. In 2013, she was forced to take a hiatus from her band The Dap-Kings, after she was diagnosed with cancer. The documentary 'Miss Sharon Jones!' follows her musical comeback.
