The Sixth Story in the Adventures of Ross Murdock
The modern city of Dover had been inhabited since the Stone Age, so by the advent of the Bronze Age, it was a thriving community, one which the three agents from the future were determined to avoid. Ashe, Murdock, and McNeil, or rather Assa, Rossa, and Maka, in the guise of Beaker traders, stayed away from the well-used trails that led in and out of Dover in search of a mystery.
This was circa 2,000 BCE and they had been sent back in time by Operation Retrograde to recover technology and perhaps even the location of a spaceship left behind by the alien race they called the Forerunners. However, their outpost, disguised as a Beaker trading post, had been destroyed by time traveling Soviet agents using weapons from the present, leaving the trio fugitives, not only from Red spies, but from the local clans who believed they were cursed by the gods. Their only hope was to hold out until the extraction team aboard the nuclear submarine USS Thetis returned just under two weeks from now and they could be transported out of Britain and back to the time gate at their base in the Arctic.
