This is one of the great untold stories of the 20th century. It is a firsthand account of a mission by an SAS soldier sent behind the Iron Curtain by MI6 to find someone who didn't necessarily want to be found and how, on a follow-up mission, he found himself manoeuvring against a mysterious KGB officer and a murder plot by Kremlin hardliners. If the plot had succeeded, it would have given the Russians the excuse they were looking for to roll out the tanks across East Germany, the Berlin Wall would not have fallen - and the map of Europe would look very different today.

Kevin Fulton was one of the British Army's most successful intelligence agents. Having been recruited to infiltrate the Provisional IRA at the height of the Troubles, he rose its ranks to an unprecedented level. Living and working undercover, he had no option other than to take part in heinous criminal activities, including the production of bombs which he knew would later kill.

If you've heard any news report on the upsurge in knife crime recently, you'll have heard the words 'county lines'.

As Erik Prince, its founder and former CEO, writes: "Hundreds of American citizens employed by private military contractors, or PMCs, would lose their lives helping our government wage wars in Afghanistan and Iraq, only to have their memory tarnished by the unfair and/or ignorant depiction of PMCs as profiteers, jackbooted thugs, or worse."

To the medievalists of ISIS, this was an affront, so they amassed 10,000 men, heavy artillery, tanks, mortars and ranks of suicide bombers to crush the uprising.
