The spaceship "SOL 23749" ran at ultralight speed in the Iperspace. Its crew was
composed from a strange couple, a lot brought together: a man and a cat. After
numerous failures and cases of madness, the scientists uncovered that only a couple
formed from a human being and a cat resisted undamaged the long travels in the
depths of the space. The Captain George Morroni was happy, because finally they
were making return home, to Rome, on Terra, after two months of mission, in which
they had uncovered three planets adapted for the human colonization. He was laid
on the hammock and with his hand trifled with the fur of Petronio, his partner-cat,
that was dozing calm near him. The man and the cat would have had to be the only
occupants of the spaceship, but hidden in the hold there was a Drill, a member of the
more dangerous alien specie of the Universe. The Drill, large as a baseball-ball, is
furnished with sharp claws, spiky teeth and a venomous sting, and he is almost
completely invisible, because his color is beyond the visible spectrum of the other
living beings. He is omnivorous, he eats also the members of his specie and he
everywhere survives, because when he is in a hostile atmosphere, he falls cataleptic,
waiting for better living conditions forhim to wake up. The reproduction of the Drill
happens with the emission of spores, is fastest and follows an exponential curve.
In only eight weeks one Drill, with his sons, could exaust the alimentary resources of
a planet as Earth. Finally the Drill is an intelligent and aggressive being. The one
that now was in the hold, he was gone up in the spaceship, during a pause on a remote
planet, without that the edge sensors revealed his presence. He was calm and hidden,
preparing to invade the Earth, pretasting the moment of his reproduction with sporing.
Nothing could stop him and all the things seemed to proceed in the best way...
