Suddenly Caliban had an idea. He consulted his datastore and confirmed that humans saw in a far more limited range of light wavelengths than he did. Nor, it appeared, did their bodies provide any source of built-in illumination. He turned around and hurried back down the tunnel, at top speed, yanking out the glow lamps, crushing them, heaving the debris in all directions. Within sixty seconds the floor of the tunnel was littered with broken lamps. It was in absolute darkness, but for the dim glow of two impossibly blue eyes about twenty meters from the building access hatch. But then Caliban shifted to infrared, and even that illumination faded away. He stretched out his arms to one wall of the tunnel, braced his legs against the opposite wall, and walked his way up until he was braced against the ceiling, between. two of the overhead supports. The odds seemed at least a little better that he would stay out of sight there. He had no real plan, no idea of how to get out. All he knew was that he had more chance of staying alive a little longer if he kept out of sight in the dark, rather than waiting passively for his fate.
He hung there, waiting, for what seemed an absurdly long time. His on-board chronometer gave him a precise report on how long he waited there, but somehow the number of minutes and seconds that flickered past was no proper measure of his situation. There was something more to it, for the odds were very good that these were the last minutes and seconds he would ever experience.
What was taking them so long?
At last there was a clang and a thump. Caliban cocked his head cautiously down to peek around the support beam that hid him from view. He turned his head toward the access hatch. “Damnit,” a voice called out. “He must have knocked all the lights out.” Caliban saw the beam of a handlamp stab out from the building side of the hatch. Like most lamps designed to give off visible light, this one cast a fair amount of infrared as well. A human figure, and then another and another and another, came through the hatch, plainly visible in infrared.
“Well, at least we know he’s still in here,” one of them said as a light beam played across the floor, revealing the smashed glow lamps. “He wouldn’t have hung around smashing the lights if he could’ get out one of the hatches.”
“Ready to do some damage, Spar?” one of the others asked with a low chuckle.
“Capture only, Jak,” a third one, the only woman, said. “Try to keep that in mind, okay?”
“Don’t like tunnels,” the one called Spar announced. “This gives me the creeps. Can’t we pull in some real lights before we go searching around in here?”
“Galaxy’s sake, it’s just one lousy robot in an H-tunnel,” the one called Jak replied. “Don’t you get all jumpy on me now.”
Suddenly the hatch behind them swung shut again, to the obvious discomfort of the four deputies. “Well, if he can’t get out, neither can we,” the woman said, her voice a bit low and nervous.
“I don’t like it,” Spar objected. “Can’t we reopen the hatch and just post a guard on it?”
“Yeah, and let the rogue punch out the guard and make a run for it,” the first voice said. “Look, Spar, the manual keypad combo for all the hatches is 274668. You get antsy, you get out that way. Just don’t get crazy on us. Come on, let’s move out. Mirta, you and me will take the east side; Spar and Jak, you take the west.”
These humans weren’t thinking clearly. Did they assume that if they could not see him, he could not
Listening carefully, he judged that the other pair of deputies had indeed gone the other way, to the western leg of the “H.” He could hear them turning the corner and moving up one arm of the tunnel.
Moving as silently as he could, Caliban worked his way back down the wall, stepped down onto the floor, and turned in the direction the two male deputies had gone. He was tempted to use the keypad combination on the building access door, but no doubt there were any number of police waiting just behind it. No. His one hope was to get past these deputies, punch in the keypad combination, and hope it worked. He made his way down to the intersection between the cross tunnel and the side tunnel and peered cautiously around the corner. There they were, on the north end. Caliban backed into the crosswise leg of the tunnel again. He braced his arms and legs against the walls and worked his way back upward to hide against the ceiling again.
