So they waited patiently, ready to shoot the hell out of any ship that made a break for it or simply decided to change position. And they closely monitored each ship; should someone try to board from space they’d know it.

The robot played the waiting game for almost three full days. By then its primary mission was a total failure—the plans it had stolen were now known, so quite obviously obsolete at that point—but what it had stolen was of some value, since they revealed strengths and current positions, and when analyzed by a specialist in military affairs would show a prospective enemy how the thinking of the Military Command and its bosses ran. Still, it couldn’t wait forever —the force positions could not be so easily or quickly changed, and any contingency plan for their dispersion must be a variation of the original. For the present, their range of options was narrowed, but the options would increase geometrically with each elapsed hour. The robot had to make its move, and it did.

A small planetary satellite officially on the records as an obsolete weather-control monitor station came within three thousand meters of a small corvette. The ship, a government courier boat, would ordinarily be unmanned while keeping station, but no ships were left unguarded at this point.

The robot, still looking like the perfect clerk, emerged from the satellite through a hatch that should not have been there. But, then, the satellite was only superficially what it appeared to be, having long ago. been copied and replaced with something infinitely more useful.

With seeming effortlessness, the robot sped to the corvette and stuck to the outer hull. It reached to its belt and pulled off a small weapon whose dangling line it attached to a small terminal that was otherwise invisible under its left arm. The robot had spent the past three days drawing enormous energy reserves to itself with the devices in the satellite; now, at capacity, it discharged through the weapon.
