From one of our most treasured BBC broadcasters, the fourth instalment in James Naughtie's brilliant spy series finds Flemyng back in Berlin, and alone as never before.

It is 1989 and although the Wall is still the Iron Curtain, the end game of the Cold War has begun. Confident that one of his own agents can provide priceless intelligence from the other side, Will Flemyng throws himself into the climactic struggle between East and West.

But fate takes a hand. A sworn enemy in the East has evidence from the Nazi era that could destroy Flemyng and his family, and he lays his trap.

The eyes of the world are on Berlin, but Flemyng faces a personal struggle for honour, and survival, in the city where he learned his trade.

For the master spy, has the end come at last?
