Clinton is teaming up with her friend, the mystery writer Louise Penny, on “State of Terror.” It has a plot that might occur to someone of Clinton’s background. A new secretary of state who is working in the administration of a rival politician tries to solve a wave of terrorist attacks. The novel comes out Oct. 12. Clinton’s husband, former President Bill Clinton, collaborated with James Patterson on the thriller “The President is Missing” and on a new novel, “The President’s Daughter,” which comes out in June.
