Distinguished biographer Beatrice Bowman is being sued for libel by a new member of the House of Lords for implicating him in a thirty-year-old terrorist outrage. At the other end of the legal spectrum, a family of South London villains gags and suffocates those who try to expose their secrets. And Inspector Caro Lyalt has to decide what to do with information from a whistle-blower that could ruin a colleague's career -- or her own. Caught in the middle of it all is barrister Trish Maguire.
