After a cabinet minister is gunned down in front of his wife and children on a London street the Provisional IRA claim responsibility. The killer, Billy Downes, makes his way back to the Falls Road in Belfast but it isn't long before a man is sent to find him. That man is army officer, an Ulsterman who takes lodging in The Falls claiming to have been away working as a merchant seaman. He doesn't know Downes identity; all he has to go on is an identikit picture and information he gleans from the locals. Any information gained has the potential to endanger the person who told him. The IRA learn that there is a man, who is unknown to the authorities in Northern Ireland, and start hunting for any outsiders; it is soon a cat and mouse came as Harry searches for Downes and the IRA hunt for him.
This superlative three part TV drama has a very natural feel; there is nothing glamourous about what is happening and Harry is far from the traditional hero. There is an almost constant feeling that things could easily go wrong for him and that would almost certainly mean torture and death. The creators could easily have made Downes a monstrous character but instead he is a fairly ordinary person, almost sympathetic at times as his commanders keep using him without risking themselves. The acting is impressive throughout; the fact that there are few familiar faces makes it feel all the more real. Ray Lonnen and Derek Thompson stand out as Harry and Downes. While most of it was filmed in Leeds rather than Belfast I doubt many viewers will realise... the only times I thought 'That's not Northern Ireland' were when prominent British Rail logos, not the Northern Ireland Railway logos, were shown... a very minor quibble indeed. The story plays out well with many moments of real tension and an ending that will stick with the viewer years after they first see it.
