Number One Fan

Castle is called in to negotiate a hostage crisis involving a murder suspect who will only speak to him, and puts his life in danger when he exchanges himself for two of the hostages. Gates allows Beckett, fired from her federal job, to assist with the investigation, even though budget cuts have prevented her reinstatement to the precinct. With the case resolved, Beckett is returned to active duty thanks to the support of an influential man met during the investigation.
