Counterstrike (1990) : 1x9

News reports claim that Count Antonio Debroca, Alexander's old friend and the reigning master of the kinghthood, has committed suicide within hours of telling Alexander that he urgently needs a face-to-face discussion about the fate of the hostages in the Middle East, as it may have an impact on the fate of Chantel, Alexander's wife. A mysterious source tells Alexander that Debroca was not lost but murdered. Alexander tells the team that he suspects his friend is murdered, but wants evidence to prove his assumption and the identity of the murderer. The team soon discovers that a murder investigation has turned into a rush to foil a madman's plot to destroy Beirut with a neutron bomb.
