The final scenes from “Detectorists” on Thursday night.

They could have found any old Treasure anywhere. But no, in the run up to Christmas with the shops piled high with special offers on thousands of cheap starter metal detectors, they had to find something identical to the incomparable Alfred jewel and find it next to a standing stone.

In January there will be reports of multiple holes at ancient sites. They will be attributed to professional nighthawks but more likely they will be the work of underinformed newbies. It will partly be the Beeb’s fault and partly the Archaeological Establishment’s, especially PAS, for saying nothing.
