Overview: Fifty years ago, Nikolai Bukharin, Lenin's right-hand man and favourite of the Bolsheviks, was shot by Stalin's henchmen after the last of the infamous show trials in Moscow. Mikhail Gorbachev recently proclaimed his death a travesty of justice and his trial a farce. Granted special permission to cover the story and the first interview with Bukharin's widow Anna, Timewatch accompanies Sir Fitzroy Maclean back to the city where he attended Bukharin's trial in 1938 to find Russians eager to talk for the first time about the terror of the '30s.
