Plot summary
When a list of fake Red John suspects is stolen, the innocent men named on it find themselves in danger. Madeleine Hightower and Bob Kirkland return. The existence of a conspiracy using the identification phrase "Tyger, Tyger" amongst California's Law Enforcement personnel is revealed. This suggests that Red John, known for his fascination with Blake's poem, may have strong connections to this organization. Bob Kirkland is murdered by Reede Smith, who tells a police officer to say that he killed him because he tried to run away, and they seal the deal by saying "Tyger, Tyger" (which indicates that they are part of the secret organization). Jane's list of suspects drops to five.
