The Umbrella Murder

In 1978 the Bulgarian author and dissident Georgi Markov was assassinated by a poisoned umbrella on Waterloo Bridge in London. His murder is the most iconic killing in almost five decades of the Cold War, and no one has ever been prosecuted for it.

The Umbrella Murder reveals the real architect and hit man behind this spectacular killing: a spy code-named Piccadilly who worked for the Bulgarian secret service and the KGB, who has been hiding for more than forty years.

Written as a modern-day thriller, and drawing on an incredible thirty-year cache of original documents and recordings and never-before-seen archive material -- some not even seen by police or secret services -- this is a jaw-dropping and page-turning search for justice in the murky underworld of intelligence and across the shifting sands of spycraft.
