Published in 2008 Wiltshire, A Journeyman’s Tale (think this might have been mentioned before but can’t find it) by Eric Crook.
“IN A modest house in Swindon, an 86-year-old man formulates exquisitely-detailed theories that turn conventional Wiltshire archaeology on its head.
“If retired builder Eric Crook is right – and his belief that he’s right is unshakeable – the remains of a neolithic princess have lain deep beneath Silbury Hill for more than 4,000 years.”
I'm a bit surprised the local paper is running a story on this book as it was published a while ago. I borrowed it from the library a couple of years back and returned it quite soon after - preferring to go with the type of 'conventional Wiltshire archaeology' that people like Jim Leary write about.
