Vengeance in Valescure is a political thriller involving MI6's concern that the outcome of the Arab Spring which has resulted in changes in government. The fear is that the new regimes may side with Russia or China andset up nuclear weapons capable of firing missiles into major European cities.

Richard Hartley, Assistant Controller at MI6, has received intelligence that the Russians have set up an arms dealership posing as a wholesale wine merchant based at Valescure in the South of France. They are providing weapons to a range of terrorist organisations in both Europe and North Africa which must be terminated. Hartley sends three agents to Valescure, including Mhairi McClure and irish terrorist serving a twenty year jail sentence. McClure is an expert on international finance having the degrees from both Oxford and Harvard prior to joining the IRA. Her incentive for this operation to succeed is the promise of a reduction to her prison sentence.

The agents remit is to pentrate the Russian operation run by Roland Canault (not his real name) who previously fled Serbia, before he was put on trial for war crimes, and destroy him and the Russian base before Hartley's fears become a reality!
