'Visitors From Beyond the Stars' Story Code '9618' by Bob and Wanda Duncan

1885: When Tony and Doug materialise inside an alien spaceship, they are immediately captured by its two crewmembers, Taureg and Centauri. The aliens reveal that their home world exhausted its protein substances centuries ago, and so they have come to Earth on a mission to raid mankind of its food resources; to aid them in their task, they have a powerful machine that can immobilise a man -or kill him. The ship lands in Mullins, Arizona, at a farm belonging to a bad-tempered farmer named Crawford; while Tony is sent to the nearby town to gather all available food supplies, Doug and Crawford hatch a plan to destroy the aliens’ machine; but the plan goes wrong, Crawford is killed and Doug’s mind is taken over by the aliens, turning him into their mindless slave. Meanwhile, Tony's attempts to warn the town Sheriff about the alien threat fall on deaf ears, and when Taureg and Centauri then decide to destroy some buildings as a demonstration of power, Tony is thrown into jail as a mischief-maker. Meanwhile, at the Tic-Toc project, members of the same alien race arrive and demand to know what happened to their scouting party, which mysteriously disappeared one hundred years earlier – and they hold Lieutenant General Kirk and his staff responsible…

Cliff-hanger: When Doug and Tony materialise in an old villa in the Italian Alps during World War I, an explosion renders them unconscious and uncovers the sarcophagus of Emperor Nero. Unseen by Doug and Tony, a sword floats out of the coffin…
