Biographer Andrew Lownie's latest book Entitled has stirred up a storm of interest with searing Royal revelations about Prince Andrew and his ex-wife Sarah Ferguson.

Royal watchers will be thrilled to know that the author himself is coming to Wells Festival of Literature in October to talk about the revelatory biography – and tickets are selling fast.

Lownie spent four years interviewing hundreds of people and tracing the lives of the couple through childhood, courtship, marriage and careers.

The result is an explosive joint biography delving deep into their relationships, lifestyles and scandals, including the Prince's links with the late Jeffrey Epstein.

The prize-winning writer's previous books include works on spy Guy Burgess, the Mountbattens and the exile of the Duke and Duchess of Windsor.

Entitled – The Rise and Fall of the House of York is published on 14 August. Andrew Lownie appears at the Festival on Thursday 23 October.
