He s found again on the beach outside the site of the murder on Richard Fielding and arrested- even his degree of schizophrenic paranoia and dysfunctional state is no legal insanity. Jesse has a go at George s slang-type associations. Ethan Foster, the widow Cynthia Fielding s lover, is told by his wife Sophie she knows he is Richard s murderer but wants to spare their teenage son Elliot the shame if he signs over all his wealth and full custody. When someone has an attack in custody, George correctly diagnoses and instructs Steve how to save him. Jesse figures out George speaks in anagrams, and his computer finds who fits father Setan, starting a new chain of events...
