Hi, it's Alexi here. There will be a brand new series very soon. Do keep an eye out for it.

But while you're waiting, I wanted to tell you about a story I've been working on for our other investigative show, the slow newscast.

Along with my producer Gary, I've been looking into the story of an unusual arson attack

carried out against a small Latvian museum

and what it reveals about the dark world of Russian secret agents.

Here's a small snippet from the episode.

It's called Rogue Russia, Agents of Mayhem.

If I have a telephone call at night, I understand that something happened, something awful happened.

It's the middle of the night in the Latvian capital, Uyga.

Solvita Vibar is woken by a phone call. The person on the other end has

some alarming news. It's about the Museum of Occupation, a museum that Solvita runs. It's one of

Latvia's most famous institutions. To many in the country, the museum is a symbol of resistance to the Soviet Union and to the Nazis.

And now, Solvita is being told, come quickly, there's trouble.

And fire in a museum, this is the most awful thing in the museum.

And I was shocked, but I immediately ran to the museum.

It's a cold February night last year, but Solvita makes her way to Riga's old town at once,

to see for herself. Soon enough, she learns what took place. At around 1 o'clock, a window of my office

on the ground floor of the museum here, you can see it, was smashed and a Molotov cocktail was thrown in,

and my office was exploded.

I've seen photographs from the scene.

They show Solvita's office covered in shattered glass.

The walls are blackened with smoke.
