A book which brings together celebrities' memories of watching Doctor Who has generated more than 20,000 pounds for a Cambridge-based charity.
Behind The Sofa includes recollections from famous faces including Jonathan Ross, Lynda Bellingham, Al Murray and Martina Cole.
It has been put together by author Steve Berry in aid of Alzheimer's Research UK, in memory of his mum Janet who died with early-onset Alzheimer's in 2009.
It also includes recollections from a host of former stars of the long-running series, including Hugh Bonneville and Tracy-Ann Oberman, with illustrations by artist Ben Morris.
The book has become popular among Doctor Who fans, known as the Whovian community.

"I've been truly astonished, both by the support of the Whovian community who have purchased the book in their thousands, and by the generosity of the celebrities who gave up their time to help. Behind The Sofa is a lasting legacy to mum and Alzheimer's Research UK."
Dr Marie Janson, director of development at Alzheimer's Research UK, which is based in Great Shelford, said:
– Dr Marie Johnson, Alzheimer's Research UK
"We are so grateful to Steve and everyone who has added their Doctor Who memories to this brilliant book. The 20,000 pounds raised from sales of Behind The Sofa already is a tremendous result, enough to fund 1,000 hours of world-class research and vital equipment for our scientists.
"This amazing contribution is bringing us closer to finding ways to diagnose, prevent, treat and cure Alzheimer's disease and other forms of dementia."
