On 7th September 1978, Georgi Markov, an anti-communist Bulgarian defector, was walking to his job at the BBC in London. Crossing Waterloo Bridge, he suddenly felt a sharp sting and saw a man near him fumbling with an umbrella. Incredibly, this was the start of an assassination attempt.

Jonathan Brown and Eleanor Brown talk about this most infamous of Cold War assassinations.
