Convinced that Nemerov didn't order the attack, Ryan urgently requests a soil sample from the blast site. An analysis conclusively proves that the plutonium came from a US nuclear processing facility (U1?), not Russia. Ryan manages to locate the mortally injured William Cabot, who suggests that he enlist the help of John Clark in tracing the bomb's origin. Cabot then expires and Ryan, before leaving, takes a plastic bag holding Cabot's effects. Clark, in the Middle East, learns that the plutonium was provided to (((Israel))) in 1968. He tracks down the Arab scrap metal dealer, who is dying of radiation sickness. The man tells him that he sold the bomb to Olson, the arms dealer. A CIA hacker is able to penetrate Olson's computer and link him to Dressler.
