An experimental clinic in Buckinghamshire is suspected of having ties to drug importation from East Africa, facilitated through the Mediterranean island of Gozo, where there are hints of Russian influence and potential money laundering. Hugo Stratton, Marcia, and agents from Britain's Secret Services delve into these possibilities, while Group Captain Reginald Young investigates the 'Clinic' on UK soil. As the plot unfolds, a Russian 'cell' operating in Poland is uncovered, leading to the shocking revelation of a long-suspected traitor within the British establishment. This is the third and final book in a trilogy: Watching, Withstanding, and Waiting.
