What does a tickle look like? That was the question eight-year-old Adam Hargreaves asked in 1971. He explains how it led his father Roger Hargreaves, to create the children's book series Mr Men.

Our guest Professor Nina Christensen, head of the Centre for Children's Literature and Media at Aarhus University, on the wider history of children's literature.

We hear a remarkable account from Captain Chris Fraser-Perry, who took part in the Jugroom Fort rescue mission, during the war in Afghanistan.

Plus from Cuba, we learn about the Mariel boatlift of 1980 in which thousands of people left for the United States and in 2022, the controversial visit to Cuba by former US President Jimmy Carter.

And the story behind the contamination of Austria's fine wine in 1985.

Our Sporting Witness episode this week looks at the first sister-brother duo to win Alpine Ski World Cup races on the same day.
