I was allowed a peek in this writing hut when it was still in his garden and it was full of a very special atmosphere. It's now been moved to the Roald Dahl Museum where everyone can see things like the hole in the back of his chair, which he cut to prevent it putting pressure on the bottom of his injured back, and the amazing set of objects on his table: the top of his leg, taken off when he had his hip replaced, the metal ball made from the silver wrappers from round the bars of chocolate he ate and much, much more.
