A POPULAR Sully author who died last year is to live in as a Doctor Who character in a new book.

Eileen Younghusband, who died in September 2016, is being featured as a fictional character in the Doctor Who universe.

Famous for her Second World War memoirs One Woman’s War and Men I Have Known, her character is joining forces with the popular Doctor Who character, Brigadier Lethbridge-Stewart.

This Doctor Who spin-off is set during the Second World War with Eileen being dispatched to solve the mystery of The Flaming Soldier.

Shaun Russell, head of publishing at Lethbridge-Stewart publisher Candy Jar, said: "Eileen worked in the filter room, the top secret hub of Britain’s air defence, and tracked the first V2 rocket into the country.

"Before she died I had a brief conversation with her about our Lethbridge-Stewart series.

"We joked about her being the first person to track an alien rocket into the country and this sparked an idea.

"Her sad death prompted us to include her in the short story The Last Duty alongside her fictional cousin, Captain Younghusand, but now we feel the time is right to discover more about Eileen’s alien fighting exploits during the Second World War."

Quentin Younghusband, Eileen’s nephew, is really pleased that Eileen’s legacy will live on.

He said: "My aunt would have been tickled pink at the fact that she is a central character in the latest book in the Lethbridge-Stewart series."

Richard Young, the artist responsible for the book cover, said: "I was aware of Eileen from seeing her on the TV, but I never knew just how famous she was until I did my preliminary research.

"It turns out that she lived quite a life.

"I'm pleased to say that the feedback I received from the family totally blew me away.

"I just hope that I have done her justice for all her fans."

A life size figure of Eileen as a 21-year-old WAAF officer stands in a replica of a filter rom at the Battle of Britain museum at Bentley Priory.

Her advice on the Women's Auxiliary Air Force was sought by historians, documentary makers and even a Hollywood scriptwriter.

Eileen’s numerous television appearances included the BBC series Britain's Greatest Generation, Channel 4’s WW2: The Last Heroes, and the ITV Wales programme Welsh Heroes of World War Two, as well as BBC’s Breakfast, The One Show and Eggheads. Her book One Woman’s War won a People’s Book Prize. Her final book Eileen’s War was written for children and was completed and published only weeks before her death.

Eileen saw Eileen’s War as her "legacy" book.

On the day of its release she said: "It is my hope that all children will read my book.

"I think it is really important to engage with young people about the Second World War.

"It’s a pivotal moment in our history. If my story can live on from generation to generation this will be wonderful."
