Jared Renfrew has lost the last appeal against his conviction for the rape and murder of Undine Kopecki, the daughter of his family estate's housekeeper. Jared promises to deliver Red John to Patrick if he gets him out by proving his innocence. Jane accepts, but has to resign and the whole CBI team risks suspension to help him. Jared's brother and business 'heir', Gardner Renfrew, opposes their efforts. Red John meanwhile has infiltrated the CBI computer network and seems to stay one move ahead, however brilliantly Patrick advances.
