In this episode of History Book Buffs, Antonia Senior talks to historian Josh Ireland about his gripping book The Death of Trotsky, which tells the extraordinary story of how Soviet dictator Joseph Stalin hunted down his greatest rival, Leon Trotsky.

After the Russian Revolution, Trotsky seemed destined to inherit power from Vladimir Lenin. Instead, Stalin outmanoeuvred him politically, forced him into exile, and then spent years trying to have him killed.

Eventually Trotsky ended up in Mexico, surrounded by spies, assassins and political fanatics. There, in 1940, Stalin’s agents finally succeeded.

Antonia and Josh explore the rivalry between Stalin and Trotsky, the psychology of revolutionary power, the Spanish Civil War networks that helped Soviet intelligence, and the extraordinary lives of the people drawn into the assassination plot — including Ramon Mercader, the man who ultimately killed Trotsky.

The result is one of the most dramatic stories of the 20th century: revolution, exile, espionage, ideology and murder.
