Rich Precolumbian archaeology professor Manuel Montero, also a well-reputed traded in antiquities, is murdered in the Nothern Calirfornia Museum of Anthropology. He was meeting a buyer for a Mayan golden pendant, the only item stolen there. His transport crew is caught, also dealing in illegal arms, but Patrick believes the motive personal. Laroche's IA investigation reduced serial cop-killer Todd Johnson's torch-murder suspects to five CBI members with opportunity, including only one with a motive: agent Madeleine Hightower was the former lover of murdered CHip Jim Rance. Links between both cases are found. Patrick however sees it all as part of Red John's master plan.
