With one of the Red John suspects dead, Jane turns his focus toward Sherriff McAllister. Noticing a fresh murder in Napa, McAllister's jurisdiction, Jane gets the CBI involved. The victim, found weighed down in a duck pond, is pizza delivery man Larry Bonner. He was in town for the wedding of Judith Bonner, a wealthy liberal, and Doug Dorfman, a blue collar worker. When Jane's antics in search of the murderer lead to the wedding being called off, Van Pelt makes an impassioned plea to the bride in favor of marriage - something that isn't lost on Wayne Rigsby. Meanwhile, Jane attempts to bait McAllister into revealing his true intentions.
