Above, a truly excellent cover for David Wade’s, aka Norman A. Daniels’ Walk the Evil Street, published in 1960. Rainbow Books had a habit of not crediting art, so we have several suspects for this one, but sadly, no perpetrator.
1978—Giorgi Markov Assassinated
Bulgarian dissident Giorgi Markov is assassinated in a scene right out of a spy novel. As he’s waiting at a bus stop near Waterloo Bridge in London, he’s jabbed in the calf with an umbrella. The man holding the umbrella apologizes and walks away, but he is in reality a Bulgarian hired killer who has just injected a ricin pellet into Markov, who develops a high fever and dies three days later.
