Throughout history, spies have used sex, seduction and emotional manipulation to achieve their shadowy aims. In this 3-part anthology, Vanessa Kirby joins espionage authors Henry Schlesinger and Michael Smith to uncover the real stories behind some of history's most explosive honeytrap operations. In Part 3, Michael and Henry tell the real spy story behind one of history's most famous murders. When Ramón Mercader attacked Marxist revolutionary Leon Trotsky at his home in Mexico, the evidence suggested a crime of passion. In reality, it was the culmination of a long and intricate honeypot operation by Stalin's secret service. Could YOU get close enough to kill? From SPYSCAPE, the home of secrets.
