An eagle-eyed forest ranger spotted bits of Roman building poking out from the forest floor in Cambridgeshire's Bedford Purlieus Wood.
And cutting-edge aerial visualisations reveal evidence of a complex of building foundations hidden in the woods. Tony and the Team investigate what these buildings were and why they were here.
It's a straightforward question, but the dig is one of the most challenging of the series: it's almost impossible for geophysics to operate in the cramped woodland environment; the diggers can't see each other's trenches for the trees; and a thick layer of autumn leaves add to the general disorientation.
But the Team manage to uncover substantial buildings, intricate finds and what looks suspiciously like a statue. Over three days they piece together a tale of Roman industry and trade, and what may be the key to understanding the site: the presence of a fancy bath-house.
