It is 1985 and MI5 has entrusted a new high stakes mission to Sergeant Tommy Henshaw, a Royal Marine Commando, agent handler, and covert intelligence specialist. While working as an agent handler in South Armagh, he volunteered for a deep cover operation, sanctioned by the Government to target the covert activities of the Provisional IRA’s secret England Department. Their sinister plot involves using London’s underworld to facilitate to assassinate Margaret Thatcher and the entire cabinet once and for all. Tommy finds himself entangled in a perilous world of prison brawls, firearms, and ruthless gangsters as he races against time to thwart the IRA’s plans. As the story unfolds, three shadowy organisations collide, collude and collaborate in the shadows of the booming fast-changing London of the 1980s.

The timer is set, the clock is ticking, and the relentless passage of time allows no room for error.
