Paul Bruce was a tough, idealistic young trooper in the SAS when he was despatched to Northern Ireland. His top-secret mission: to execute IRA suspects in cold blood. Bruce and three SAS comrades shot down one terrified victim after another, leaving their bodies to be buried in deep, unmarked woodland graves. The soldiers grew their hair long and drove civilian cars. But they always carried pistols and sub-machine guns. In this historic book the author reveals the brutal truth about the Nemesis File.
