Ken is involved with the fire service again - this time in the pursuit of a bent fireman turned arsonist. Harry, meanwhile, embarks on a self-assertiveness course.
Harry organises a charity ball with a dodgy character who runs off with all the money, leaving Harry to face an investigative journalist's cameras; he is forced into promising to replace the enire sum. The Texas Rangers, meanwhile, are thought responsible for some industrial espionage - which threatens to close them down. Rocky helps uncover the real leak, and Boon re-establishes relations with Margaret.
Ken and Margaret finally track down the runaway Jay, but not before he's spent all the money. During the course of an unusual blackmail case, Margaret discovers that her new boyfriend is a liar. In the end, Boon does so well at both cases that she asks him to be her partner.

Ken becomes a minder for a spy who has just been released from prison - a newspaper has an exclusive story contract and wants to protect its investment. It's not easy, however: rival newshounds are soon on the scent, and even the secret services are traling behind...
