British author Tim Adler's latest book, "House of Redgrave: The Secret Lives of a Theatrical Dynasty", is filled with bombshell revelations about one of Britain's most celebrated acting families. On this week's Poliwood, Roger Simon and Lionel Chetwynd delve into the sordid politics to which Vanessa Redgrave and her brother Corin were dedicated. How did these children of privilege come to think of themselves as leaders of the working class? And why did they embrace the leader of the Workers Revolutionary Party even after he admitted to having "red sex slaves"?
