At the Bar-Tor farm in Dartmoor, owned by young Robert Hamlin. Downstairs, on the red land of Devon, a porcelain clay deposit was found, the value of which, although not fantastic, was large enough to make searchers be interested in the possibilities of buying all the property. Their idea was to get it before Robert Hamlin realized that he had a hidden asset that cost a lot more than all of his agricultural land. But they did not outsmart him.
