Monk's biggest fan, Marci Maven, who's as nutty and intense as ever, is at home redesigning her Monk web site. Meanwhile, across the street, John Ringel returns home from a jog and discovers his wife mauled to death by a wild animal. Suspecting Marci's vicious dog, Otto, Ringel calls the police, who arrive at Marci's house to question her. But Marci insists it couldn't have been Otto. Otto is dead, and she shows them the dog's grave to prove it.
