The Bulgarian defector Georgi Markov was killed by a pellet of ricin in the thigh, only about half a milligram. He died 3 days later vomiting blood.

Ricin was the poison used to murder Bulgarian exile Georgi Markov in a poisoned umbrella assassination in London in 1978.

The Bulgarian defector Georgi Markov was killed by a pellet of ricin in the thigh...

Almost the same week, another Bulgarian defector, Vladimir Kostov, was in similar way attacked in Paris. He survived (and lives now in Bulgaria) after being very seriously ill for rather long time.

I mean, it gives some hope, isn't it?
