In Thatcher's Spy, the Cold War meets Northern Ireland's Dirty War in the remarkable real-life story of a deep under-cover British intelligence agent, a man now doomed forever to look over his shoulder. In March 1985, as he climbed the six steps of Margaret Thatcher's prime-ministerial jet on the runway of RAF Aldergrove, little did Willie Carlin know the role Freddie Scappaticci played in saving his life. 

From its early beginnings in World War II, the Special Air Service (SAS) has won renown in some of the most dramatic, dangerous and controversial military special operations of the 20th century. It is a secretive and mysterious unit, whose operations and internal structures are hidden from the public eye. Now, one of its longest-serving veterans offers a glimpse into the shadowy world of the SAS. Rusty Firmin spent an incredible 15 years with 'The Regiment' and was a key figure in the assault of the Iranian Embassy in London in May 1980. 

Born ‘a ragged-arsed kid from the backstreets of Glasgow’, McCallion joined the Paras to escape a miserable home life and find the family he longed for. After six tense tours in Ulster, McCallion gave up everything to move to South Africa in the hope of qualifying for the highly elite South African Special Forces. Having succeeded in joining the Recces, McCallion was involved in plots to assassinate Robert Mugabe and Joshua Nkomo.

South Armagh, 1989: cheering mobs stand over the body of a British soldier. He is the ninth to have been killed by the so-called Border Fox, an IRA sniper whose activities have helped make this area of the United Kingdom the most feared killing ground in Western Europe. The British government is determined to break the tightly knit South Armagh Brigade of the IRA before more lives are lost.

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. So highly was he valued by IRA leaders that he was promoted to serve in its infamous internal police - ironically, his job was now to root out and kill informers.

A pause resisting, real life thriller recounting the story of the Irish Republican Army Active Service Unit, placed in deep cover in London, and their murderous campaign against the British establishment...This is the true story of a deadly cat and mouse game played out on the streets of London that resulted in the infamous armed stand off at what would later be called the Balcombe Street Siege.

Michael Asher served in Northern Ireland with the Paras at the height of the IRA campaigns of the 1970s. He witnessed the result of using highly motivated assault troops in 'peacekeeping operations'. His depiction of the strengths and weaknesses of the British Army's elite airborne forces comes from his personal experience of what it was like for ordinary soldiers. From the Paras to the SAS and then service with the Special Patrol Group in Northern Ireland, Michael Asher's military odyssey eventually led him to leave the forces for a new life in the Sudanese desert. 

Summer 2006, Afghanistan: an apparently deserted village, and a rapidly ticking clock... The relentless Taliban ambush which followed saw several British soldiers dead, two armoured vehicles destroyed - and Corporal of Horse Michael Flynn awarded an MC to go alongside his Conspicuous Gallantry Cross. Mick Flynn has never backed away from a challenge.

As a senior non-commissioned officer of Delta Force, the most elite and secretive special operations unit in the US military, Command Sergeant Major Tom Satterly fought some of this country's most fearsome enemies. Tom is a legend even among other Tier One special operators. Yet the enemy that cost him three marriages, and ruined his health physically and psychologically, existed in his brain. Told through Satterly's firsthand experiences, it also weaves in the reasons for his career-long battle against the most insidious enemy of all: post-traumatic stress.

Go! Go! Go! tells the action-packed story of the 1980 Iranian Embassy siege. It is a comprehensive and gripping account of an unforgettable six-day drama that shook Britain - and the wider world - to the core. Drawing on original and unseen source material from ex-SAS soldier Rusty Firmin, the police and the British government, Go! Go! Go! takes us to the heart of the whole operation.   

In March 1978, at the culmination of Operation Julie, 15 defendants, including doctors, research chemists, a writer, and "professional" drug dealers were sentenced to a combined total of 124 years' imprisonment. Operation Julie is still today the point of reference for all British undercover operations and training. In 2011, the BBC claimed this massive and unique police operation was the start of the war on drugs. Stephen Bentley, was one of four undercover detectives engaged on Operation Julie, one of the world's largest drug busts.  

The 'Dirty Dozen' were a ruthless federation of criminals who ran the armed robbery game in London for over a decade. When charismatic leader 'Gentleman' Jim Doyle was jailed, the innovative but violent Bradish twins, Sean and Vincent, stepped up to take the throne. Hardened by a life in London's most lawless corners, they recruited a tight-knit crew to forge a reputation as the brutal kings of their underworld trade. Banks, security vans, post offices, travel agents - anywhere was fair game and nowhere was safe. 

Terrorist leaders are not benevolent men inclined to make peace but vicious bullies. The IRA was the Islamic State of its day. Northern Ireland, Iraq, and Afghanistan are similar wars. In these, an insurgency like the IRA/Sinn Fein mix is the main problem. A proven solution is the rule of law, where police intelligence dominates because investigative practices fail. The approach - widely misrepresented and commonly misunderstood - devastated the IRA. Some terrorists were killed, most were in prison, and many were on the run.

In July 2009 Geraint (Gez) Jones was sitting in Camp Bastion, Afghanistan, with the rest of The Firm - Danny, Jay, Toby and Jake, his four closest friends, all junior NCOs and combat-hardened infantrymen. Thanks to the mangled remains of a Jackal vehicle left tactlessly outside their tent, IEDs were never far from their mind. Within days they’d be on the ground in Musa Qala with the rest of 3 Platoon - a mixed bunch of men Gez would die for.  

Rob Driscoll, former sergeant with 42 Commando, Royal Marines, served tours in Iraq, Kuwait and Kosovo. A born leader of fighting men, with the medals to prove it, he also endured three tours in Afghanistan. The third of those will go down in history as one of the UK military's darkest hours, for it marked the first time a British serviceman has been tried for a murder on the battlefield since the Second World War.
