One hot day in 1922, a young man called John Pull strolled across the Sussex downland at Blackpatch, just outside Worthing. He was the victim of a First World War gas attack and he had come there looking for fresh air and peace. What he discovered was one of the very few Stone Age settlements in England.
John Pull wasn't an archaeologist or antiquarian but a 23-year-old gramophone salesman - which made him highly unpopular with the archaeological elite. His work was sneered at, his finds were lost, the site was bulldozed - and, in a tragic twist of fate, he was murdered in a bank robbery.
Eighty years after Pull first set foot on this hill, Time Team came to reassess his work. Was this really the site of a prehistoric village? And what about a mysterious second site, which Pull recorded but had since been lost?
