The Umbrella Murder By Ulrik Skotte

September 1978: exiled Bulgarian dissident Georgi Markov is murdered in broad daylight on Waterloo Bridge, London with a poison-tipped umbrella. It would become the most infamous unsolved killing of the Cold War. Many years later, young journalist Ulrik Skotte is approached with explosive new information about a man alleged to be responsible for Markov’s death – a spy code-named Piccadilly who worked for the Bulgarian secret service. This one meeting would launch Skotte into a hunt for the killer lasting more than a quarter of a century, bringing him face-to-face with eccentric conspiracy theorists, a washed-up former dictator, ageing Danish spooks – and, ultimately, with Agent Piccadilly himself.
