For their part, the robots were doing their best to stop it. Large machines, obviously converted from mining work, had been modified to lift huge slabs of the building material to the top of the pool, where utility robots with laser torches were welding the higher sections together, trying for more room, bathing the area in various sections in showers of yellow sparks.
It was a massive job, the reservoir covering many acres, as the robots worked frantically to finish before the next rain. And to Derec’s mind, this could be no more than a stopgap measure, for unless the rain was halted, it would overflow even the extra section in a day or two.
“What happens if the water overflows?” he asked Rec.”
I am unable to speculate on such matters, Friend Derec,” the robot said. “It is not overflowing. When it does, I will witness.”
“Right,” Derec said, and moved forward, closing on the workers.
“Do not get too close,” Rec called. “It is dangerous for you.”
Derec ignored him and moved closer, recognizing Euler, who was helping with the movement of a slab. He was directing a large, heavy-based machine with a telescoping arm that held a six-by-six-meter slab in magnetic grips. He was holding his pincers at the approximate distance the arm had yet to travel so that it would be flush with the edge of the pool and the slab next to it. Utility robots physically guided the slabs to the ground and held them so the welders could set to work immediately.
“Euler!” Derec called, the robot jerking to the sound of his name.
“It is too dangerous for you here!” Euler called back, waving him away. “We have no safety controls over this area!”
“I’ll only stay a centad,” Derec said, moving up close to him. He could look past the end of the last slab and see the dark waters churning the top of the pool. In the distance, all around the reservoir, he could see the same operation being repeated by other crews.
“What are you doing here?” Euler asked him.
“I had to see for myself,” Derec answered. “I knew the levels were rising. Why don’t you stop the building pace and let these waters recede?”
“I can’t tell you why,” Euler said.
“But what happens when this overflows?”
“We lose the treatment plant,” Euler said, holding his pincers up to signify to the arm to stop moving the slab. Then he motioned toward the ground, the arm bringing the slab down very slowly. “We lose much of our mining operations. We lose a great many miners. We will have failed.”
“Then stop the building!”
“We can’t!”
Just then, a utility robot working the slab was bumped slightly by the moving metal and lost its footing on the wet floor. Soundlessly and without drama, it slipped from the edge of the pool and fell into the dark waters, disappearing immediately.
Everything stopped.
Euler pushed past Derec to hurry to the water’s edge, where he stood, head down, watching. The rest of the crew did the same, lining up quietly beside the water. Derec moved to join Euler.
“I’m sorry,” he said.
Euler slowly turned his head to look at the boy, not saying anything for a long time. “I should have paid more attention,” he said.
“How deep is the water?” Derec asked.
“Very deep,” Euler replied. “I was talking with you and didn’t give the job my complete attention.”
“Can it be saved?”
“Had there been more time,” Euler said, “the job would have been studied for safety and feasibility and this wouldn’t have happened. Had I known better, I wouldn’t have allowed you to come so close. A robot is lost, and the supervisor is to blame.”
“There was nothing you could have done,” Derec said.
“A robot is dead today,” Euler told him. “I will not answer any more of your questions right now.”
Chapter 6. The Tunnels
“If the city keeps moving,” Katherine asked, “how can you take me to the location of the murder?”
“Triangulation,” Eve, the witness, said. “Using the Compass Tower as one point and the exact position of the sun at a given time as another point, my sensors are able to triangulate the position where I first witnessed the body. The time is the only real factor at this point. We must gauge the sun in exactly 13.24 decads to get the position right.”
They were walking through the city, Katherine feeling a mixture of fear and exuberance at her first solo trip outside. They were walking high up, above many of the buildings, bridges between structures seemingly growing for her to walk across, then melting away after her passage. Eve apparently needed the height in order to take the precise measurements.
Katherine was angry at Derec for his lack of interest in their predicament, but she knew him well enough to know how stubborn he could be. She, in fact, knew him far better than he knew himself, and that was maddening. They were caught in a web of intrigue that existed on a massive level, and as long as she was trapped there, she had to play the situation with as much control as she could muster. And that included not telling Derec any more about his life than he could figure out for himself. Her own existence was at stake, and until she could escape the maze that had locked up their activities, she desperately feared saying anything more.
She had to get away from Robot City. The pain had increased since her arrival here, and, for the first time in her life, death was a topic she found herself dwelling upon.
And her only crime was love.
She felt the tears begin to well up and fought them back with an iron will. They wouldn’t help her here. Nothing would, except her own tenacity and intelligence.
“Tell me about your involvement in David’s death,” she asked Eve, who was busy calibrating against the sun.
“In approximately two decads,” the robot said, “it will have happened exactly nine days ago. We go down from here.”
Eve moved directly to the corner of the six-story structure they were standing upon, and railed stairs formed for them to walk down. As they descended, the robot continued talking.
“I was called upon to witness the attempts to free Friend David from an enclosed room.”
“An enclosed room?” Katherine said. “I’ve never heard about this. How could he get trapped like that in this place?”
“The room grew around him.” Eve said. They reached street level and the robot headed west, away from the Compass Tower. “It sealed him in and wouldn’t let him leave.”
“Why?”
“I do not know.”
“Does anyone know?”
“I do not know.”
“All right,” Katherine said, watching a team of robots carry what looked to be gymnasium equipment into one of the buildings. “Just report what you saw.”
“Gladly. I was called upon to witness the attempt to free Friend David from the sealed room. When I arrived, Supervisor Dante was already on the scene… ”The robot stopped moving and for several seconds stared up into the sun. “Precisely here.” Eve pointed to a section of the street. “Friend David was caught inside the structure and we could hear him shouting to be let out.”
“Who?”
“Myself, Supervisor Dante, a utility robot with a torch, and another household utility robot who first discovered Friend David’s problem.”
“What happened then?”
“Then Supervisor Dante asked Utility Robot #237-5 if the laser torch was safe to use in such close proximity to a human being, and Utility Robot #237-5 assured him that it was. At that point, Supervisor Dante tried to reason with the room to release Friend David, and failing that, he requested that the room be cut into with the torch.”
“And that request was complied with?”
“Yes. Supervisor Dante, in fact, asked Utility Robot #237-5 to complete the project quickly.”
“Why?”
“I do not know.”
Katherine thought about the nature of the witness and asked another question. “Were there any other events that coincided with this event?”
“Yes,” Eve said. “Food Services complained that Friend David could not be served lunch on time and inquired if that would be dangerous to his health; several of the supervisors were meeting in the Compass Tower to discuss ways in which Friend David might have come to the city without their knowledge; and the city itself was put on general security alert.”
