The LAPD, now operating under post 9/11 rules, think the stolen money was used to finance a terrorist training camp. Thoughts of the original murder victim are lost in the federal zeal, and when it seems the killer will be set free to aid the feds' terrorist hunt, Bosch quickly falls foul of both his old colleagues and the FBI.
