Andrew Lownie has spent four years researching the lives of Prince Andrew and Sarah Ferguson, the Duke and Duchess of York.

The book is full of dramatic details of lives spent sailing very close to the wind but mostly protected by their royal status.

What Andrew Lownie tells me will stop you in your tracks.

Published this month is a new book about the Yorks, Andrew and Sarah. The title of the book 'Entitled' says it all.

Being royal is not a job you can apply for. If you decide to walk away from your royal identity or are pushed away from it just what are you left with?

This book,'Traitor King', tells the story of an inglorious royal. It is a shocking example of what happens when inherited status is randomly given to a person who is clearly not up to the task. The book is the basis of the Channel 4 programme that shed light on the whole episode.

As well as telling the historical story Andrew Lownie discusses the lessons that can be learned by the present Royal Family. Maybe food for thought for Harry and Meghan.

The Cotswolds are in the news,but before the area was discovered by rich Americans it was a fertile area for thought and creativity. The village of Great Tew was where John Lloyd and John Mitchinson met. They both lived there in historic cottages. This is where they came up with the idea of the TV show QI.

In this episode they introduce their Book of General Ignorance.

The original chair of QI was Stephen Fry and he was replaced by Sandi Toksvig. Here she introduces her story Melted into Air.

Journalist Jon Ronson explains how he researched his amazing book 'Them - Adventures with Extremists' and philosopher Simon Blackburn explores the notion of being good. The interview was recorded 20 years ago but the quandaries remain just the same.
