Terry Keegan is an agent with British Intelligence.
At least he is at the end of the first of the two-book action series about the man. Before then he was a patsy that no one expected to survive more than a day and when he did, not only were the bad guys wanting him dead but so were the supposed good guys.
For a few good years of his adult life, Keegan had been a footballer. He played on a lower division team not being good enough for the big league but he loved the game and it paid, barely, the bills, and that was enough. Then a lousy kick by an opponent ruined his knee and ended his career. After that, it was driving lorries long distance that paid the bills even if it did mean a knee that seemed to always throb.
Things did not go well for Keegan. He was never a stupid man but he was not particularly good at anything so doing an occasional job for an old friend who was several shades off from the straight and narrow seemed a way to make ends meet. Then he made the mistake of falling for his friend's girl, she gets pregnant and turns out to be a bad news for both of them, Keegan's old friend becomes a bad enemy and Keegan finds himself heading to prison for a year when caught with a load of illegal goods. It was all very confusing and very soap-operatic except that out of the deal did come Keegan's little daughter, Ruthie, and whatever else bad might go his way, at least she was one shiny mark in an otherwise drab life. Driving truck was boring and painful but Ruthie was worth it. She was even worth having to borrow money to get a new truck to keep earning a living, even though that meant borrowing from his old enemy/friend.
That's when a division of British Intelligence came up with a plan to make a huge strike against the IRA and in doing so ensure that the department, marked for elimination, would go on. To pull off their scheme, they needed a patsy, one who could drive a truck and one that no one would care too much when that driver was killed. They contacted a broker into the underworld who looked up an old friend who just happened to have an enemy who drove a truck and who had gotten himself into hock.
The plan was simple. The patsy drives the truck. The IRA hijacks the truck and things get interesting thereafter. The patsy would, of course, be killed by the IRA but that was why they chose a nobody.
Keegan was a nobody. But he was also nobody should mess with.
