The Umbrella Murder
London, United KingdomSeptember 7, 1978
On September 7, 1978, Bulgarian dissident Georgi Markov was walking across Waterloo Bridge in London when he felt a sting in his leg. He died three days later from ricin poisoning delivered by a modified umbrella tip. The attack was widely attributed to the Bulgarian secret service working with the Soviet KGB. No one was ever prosecuted.
