So the folks at the BBC studios have asked me to share a new history podcast that I think you'll love.

It's called The History Bureau.

This week they released their first season, Putin and the apartment bombs.

In September 1999, weeks after Vladimir Putin became prime minister, four bombs blew up four apartment buildings

across Russia, killing hundreds of people while they slept.

The attacks plunged the country into panic.

Families fled their homes.

Residents patrolled their blocks around the clock, and an entire nation was paralyzed with fear.

But who did it?

It's a mystery that's fueled some chilling theories.

Over 25 years later, presenter Helena Merriman returns to the story with the reporters who were there on the ground.

You can find the History Bureau, Putin and the apartment bombs, on BBC.com, or wherever you get your

podcasts. And if you're in the UK, you can listen on BBC sounds. And now, here's a teaser from the show.

This is a story about four bombs.

Four bombs that blew up four apartments in Russia in 1999, killing some 300 people.

Old news, you might think.

Except, here's the thing.

This story, it's never quite made sense.

What's your take on it now?

Who do you think plotted the bombs?

I think the more you look at it, the more you kind of wonder.

A lot of what we should know has been classified or buried or covered up.
