Buck and Dolly Madison are agents of the CIA.
Officially they might be retired, or not. With the Madisons it is often hard to tell. Retirement does not suit either one of them so even though they have reached the age where they could chuck it all, it is not likely they would.
Buck is James Buckley Madison. It is obvious where his nickname comes from and no one who calls him anything would use his given name. He has been Buck to everyone for as long as anyone can remember.
Dolly is Melissa Madison but again no one calls her that. Since the time she married Buck 30 years before, the nickname of Dolly seemed appropriate and since she liked it, Dolly it has been for three decades.
Buck had been an officer in the Paratroopers, rising to the rank of Colonel during his full 20 years of military service. After retiring, he accepted a job with the CIA and worked for them nearly 20 more. Now 60, he is still in good physical condition and is pleased to still have his own hair, though quite a bit grayer than it once was. He is supposed to be retired but as mentioned above, that is not the whole truth. Should something come up, which it did now and then, he was available.
Dolly was also an employee of the CIA being a very good analyst specializing in China and the Far East. She may have actually retired but her knowledge and experience were such that she was always on call so, being as smart as she was, she kept up with all she could. She is described as "a 'purple-suiter,' someone who could see beyond the parochial interests of just one service." When with the Agency, she split her time between Langley and Hong Kong. In her years she worked not only with fellow agents but also with MI-5, the FBI, and the Secret Service.
Both Buck and Dolly are, if true be told, adventure junkies. They also love travel and hitting new places and with each being an experienced licensed pilot, they can get themselves to places even if no one wants to. Once there, should trouble happen, both are very capable of taking care of themselves. Buck is a marksman. Dolly is a master at "kajukenbo", a style of martial arts best described as dirty street fighting. She is a black belt in Karate, Judo, Kendo, Karate, and Kung Fu.
Messing with either is not a smart thing.
