Communist Bulgaria was home to a furtive cooking craze on a massive scale: women swapping recipes on scraps of paper, with strangers on trams, even at funerals. The historian and writer Albena Shkodrova sees this fascinating phenomenon as a form of subversion; we called her up to ask why. Also this week: Happy Birthday Schengen, an accidental invasion, and an end to Sweden's longest-running murder mystery.

Less than a fifth of the biographies on Wikipedia are those of women; Rebecca O'Neill is part of a movement to fix that. We talk to her about her quest to write famous Irish women into the Wikiverse, as well as how the site helps minority languages to stay alive. Also this week: Merkel rises above it, and theatre gets political in Albania.

Last year a terrible disaster struck the Losharik, a highly advanced Russian submarine. But what happened? And what was the submarine doing so close to European shores? This mystery has fascinated the Norwegian journalist Thomas Nilsen, one of the authors of a New York Times investigation into the Losharik disaster. We talked to him about why Russia is so interested in what lies beneath these waters. Spoiler alert: your internet connection depends on it.

Renia's diary spent decades locked in a bank vault. Like many teenagers, she had used it to vent about stupid fights with her friends and to record the thrill of her first kiss. And when the war came, she used it to document the relentless killing of Jews in the town where she lived. Ania Jakubek is on the line from Warsaw to tell us the extraordinary story of Renia Spiegel, and why it stayed unknown for so long. We're also talking about promising signs that Europeans are becoming less bigoted. Oh, and there's a dog.

Countries all around Europe are dealing with the same dilemma: what to do with citizens who went to join ISIS. Tiny Kosovo is alone in opting to bring back a large group of its citizens when other countries are turning their backs. To find out why, Dominic talked to AJ Naddaff, who spent months researching why so many left Kosovo to fight, and the country's humane response to bringing people back. 

Over on the western edge of Europe Katy's been chatting to the French writer Maxime Calligaro about why the Brussels bubble is a surprisingly great place to set a crime novel. Maxime and Katy also spoke at the Ancienne Belgique last week about how to make Europe less boring (you can watch it here). Thanks Liveurope for hosting! 

This week a brilliant young journalist was shot dead in Northern Ireland, on the 21st anniversary of the Good Friday peace agreement. The senseless death of Lyra McKee is a reminder of a conflict that most in the country have put behind them. Her friend, the writer Susan McKay, is here with a very moving tribute to a remarkable person.

Also this week: a rebellion in London, rising from the ashes in Paris, and the magnificent species that is the European honey bee. 

This week The Europeans are heading underground to the nearest bunker. Julie McDowall, Cold War writer and expert on all things atomic, is on the line from Glasgow to talk about how different countries in Europe planned for nuclear war and what it’s like to visit Chernobyl, three decades after the disaster. We also talk about the woman shaking up Estonian politics, questionable ethics in Italian opera, and Slovenian sandwiches.

A special show marking A WHOLE YEAR OF THE PODCAST! Extra brilliant guests are here to help us mark this very narcissistic edition of anniversary annexe/commemoration corner. Flavia Kleiner, whose Operation Libero has been waging a quietly successful war against rightwing populism in Switzerland, calls in from Zurich with some lessons for the rest of Europe. And Andrea Chalupa is here to discuss her new film Gareth Jones, about a courageous Welsh journalist's battle to tell the truth about the famine her grandfather survived in Ukraine 85 years ago. Plus: vote-buying, espionage, and a few splashes of prosecco.

A hundred years on from the end of World War I, we wanted to look at an aspect of the conflict we don't often talk about: the role of millions of troops of colour who fought for European powers. The excellent Christian Koller, professor of modern history at Zurich University, is here to help us explore what life was like for African and Asian soldiers who were often dismissed as 'savages' while risking their lives for European governments.

Also: France faces its past, European conservatives face their future, and Dominic faces a lifetime of incessant church bells.

What's in a name? A lot, if you're Macedonia. Emil Atanasovski is here to talk us through one of the most confusing questions in the Balkans, thank god. Transatlantic movie man Kevin Sachs is on the line to explain why Netflix is about to get a lot more European, with his tips for stylish German television thrown in for free. Plus bears, trains, and ancient weapons, we've got it all this week.

We couldn't have two more different interviews for you this week: we're talking anti-Semitism in Germany and the art of remaining zen on a beach in Scotland.

After two German rappers sparked national outrage with lyrics about the Holocaust, Human Rights Watch Germany's chief Wenzel Michalski is on the line to talk about his all too personal experience of Europe's rising anti-Semitism problem.

Why throw stones when you can turn them into art instead? Scottish photographer Andy Buchanan brings us the weird, wonderful and unexpectedly hilarious story of the European Stone Stacking Championships.

Plus, Macron Does America and Bulgaria Does It Wrong. And why not stick around and Take A Chance On Dominic's happy ending this week?
