Four bombs. Twelve days. Hundreds dead. What really happened in Russia in September 1999?

Helena speaks to BBC foreign correspondent Andrew Harding to revisit a story that has haunted him for decades. Following the collapse of the Soviet Union, Harding takes us inside a world of power struggles, inflation and a country on the brink. Then, in September 1999, just weeks after Vladimir Putin becomes Prime Minister, the apartment bombs begin. Russia is gripped by fear. The question is: who did it?

In Season 1 of The History Bureau, presenter Helena Merriman returns to one of the most contested -- and consequential-- stories in modern Russia. In September 1999, just weeks after Vladimir Putin became Prime Minister, four bombs blew up four apartments buildings across Russia. The bombs exploded in the middle of the night, killing hundreds of people while they slept. In this season, Merriman returns to the story with the reporters who were there on the ground. What did they get right first time around? And, in the chaos and confusion of unfolding events, what did they miss?
