'Down Trident'; what if peaceful protest isn't enough. The United King-dom submarine borne nuclear deterrent is carried in four Vanguard Class nuclear powered submarines based at Faslane on the River Clyde. They enjoy a security regime second to none. Imagine a scenario where a ter-rorist group manage to put the safety and security of the submarine fleet at risk and succeed in preventing these vessels from going about their lawful business under the waves. One woman recruits a small team of extremists bent on destruction. Together they set out to infiltrate the many groups of activists and protestors campaigning to "Ban the Bomb." With guile, deception and half truths she bends others to her will. In this work of plausible fiction the Royal Navy is tested to the limit as our anti-hero takes the nation to the brink of disaster.
