Thatcher's Spy
My Life as an M15 Agent Inside Sinn Féin
By Willie Carlin

March 1985, as he climbed the six steps of Margaret Thatcher’s
prime-ministerial jet, little did Willie Carlin know the role Freddie
Scappaticci played in saving his life. So began the dramatic
extraction of Margaret Thatcher’s key undercover agent in Sinn
Féin—Willie Carlin, aka Agent 3007. For 11 years the former
British soldier worked alongside former IRA commander Martin
McGuinness in the republican movement’s political wing in
Derry. He was MI5’s man at McGuinness’ side and gave the
British State unprecedented insight into the IRA leader’s strategic thinking.
