Rocky's in love again. This time it's with the delectable Guiseppina, daughter of the owner of 'The Pizza Palace', an establishement so fortified that Rocky jokes about mafia connections...

Harry, meanwhile, is planning a trip to Las Vegas, and Ken is involved in a number of mysterious parcels.

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.
