Jassy Vane is an operative for the Jamaican government.
A beautiful, sexy lady of the Caribbean, the kind male tourists follow with their eyes everywhere she goes, Vane runs a successful advertising agency in Kingston. In her late 20s, she is tall, black, shapely, athletic, and very intelligent. Her work takes her all over the island nation and often to surrounding countries and she is a familiar figure in a variety of locales. She is also a tough, take-care-of-herself undercover operative for the Jamaican Security who works cases involving international troubles that find their way to Jamaica. Using her advertising business as a front, she seldom needs more of an excuse that that to explain her presence.
Vane's boss is Robin McKay, an experienced black man in his mid 50's who hold the position of Police Commissioner, in charge of all the law enforcement on the island. The fact that he also runs Jamaican Security is a fact not known to many, even as the existence of Jamaican Security is not widely known. In his role as head of Security, McKay is well aware of the fact that many things happen in a country that are legal but might not be in the best interests of the nation as a whole. It is his job to find and rectify such situations. Vane enjoys a close bond with her boss, McKay, and with his wife of many years, Helen.
As the series begins, a new member to the security force is brought in, a civilian plantation owner named Peter Blackmore, a man roughly the same age as Vane and not one to get involved in activity outside his sugar cane business. He is known by McKay to be a highly resourceful man who, in fairly good physical shape, is highly skilled at self-defense though never having taken any special training. His position on the island, that of a wealthy but somewhat reclusive landowner, gets him into the upper levels of society to mingle with the power-brokers, some of whom are often the problems Security must face.
Jamaica is beautifully situated to be a stating area for all sorts of illicit or covert activities. Near Cuba, access to Central and South America, and a popular resort island, it gets its share of espionage. Vane's job, under the command of McKay and with the help of Blackmore, is to keep her citizens safe.
