A former national newspaper’s celebrity interviewer turned novelist will be making her debut at one of the country’s most respected literary events.

Jessica Fellowes – the niece of Downton Abbey creator Lord Julian Fellowes – is one of 25 authors appearing at the Raworths Harrogate Literature Festival, which begins on Thursday, October 17, and runs until Sunday, October 20.

Being held in Harrogate’s Crown Hotel, the four-day event – now in its ninth year – is again being delivered by Harrogate International Festivals.

Jessica’s visit comes hot on the heels of the release of her third book in the best-selling Mitford Murders series. The Mitford Scandal continues the saga – part fact, part fiction – with the legendary siblings taking centre stage.

The Golden Age-style crime novels, which The Guardian described as “absolute blissikins” and radio and TV presenter Graham Norton said were “an extraordinary meld of fact and fiction”, are soon to be turned into a major TV drama by the makers of The Crown.

Putting the Mitford Murders to one side, Jessica Fellowes is best-known for her work as the author of five official Downton Abbey companion books, a number of which have made both the New York Times and Sunday Times bestseller list.

She has written for publications including the Daily Telegraph, Guardian, Sunday Times and The Lady. Jessica is the former deputy editor of Country Life and a Mail on Sunday columnist.

Helen Donkin, Harrogate International Festivals literary manager, said: “We are delighted to have Jessica joining us at this year’s Raworths Harrogate Literature Festival.

“Her novels featuring the Mitford sisters have become must-reads for those fascinated by the siblings who were amongst the most written and gossiped about ‘A-List celebrities’ of their day.”
