Two unrelated events conspire to produce an explosion of international duplicity, political and commercial intrigue and a string of assasinations. When two of the most powerful families in the world go to war and when a coup in a South American banana republic has the potential to topple the British Prime Minister, the services of Britain's most secret of secret services are called into action. Section P, run by the awesome figure of Sir Harry Buchanan, has an even deadlier secret - an assassin so ruthless and so beautiful that she is probably the most dangerous woman in the world. She is known as The Clarion Resource.
