In 1999, a teenager's debut book unintentionally caused a royal scandal in Belgium that wouldn't be resolved for more than 20 years.

Each evening after he'd finished his homework, Mario Danneels dedicated his spare time writing a biography of Queen Paola. While researching her, he'd discovered that her husband, King Albert II, had fathered a child outside of his marriage.

It was just one sentence in his book but once the revelation was published it caused headlines across Europe which, as Mario tells Daniel Rosney, would weigh heavily on him until 2020.
