Fiddlers Three

Tommy Taylor and "The Professor", two sailors returning from leave to Portsmouth, pick up Lydia, a Wren, on the road but get a puncture as they reach Stonehenge. The professor tells them of an old legend that those caught at Stonehenge at midnight on midsummer's night are transported back in time. Moments later the area is struck by lightning. Nearby a group of Roman soldiers have suddenly appeared whom they initially mistake for members of ENSA. However, they swiftly prove to be genuine Romans who arrest them and threaten instant death unless they can prove they are Druids.
