If you ran into Frank Meehan strolling along the banks of the Clyde estuary near his home in Helensburgh, you wouldn't notice much that was remarkable about him. He looks like any other pensioner enjoying a peaceful retirement.
But, now in his 10th decade, Frank can look back on a life spent at the heart of some of the most dramatic moments in the 40-year nuclear stand-off between the Soviet Union and the West.
Frank grew up in Clydebank, a town about eight miles west of Glasgow, famous for shipbuilding.
But he spent four decades as a US diplomat living, almost exclusively, behind the Iron Curtain in Communist Eastern Europe.
