Near the third turbine stood an arc of lacy metal just high enough for a man to walk under. At the spot in the arc normally occupied by the keystone was Gavin’s paradox generator. A table filled with a snarl of equipment sat next to the arc.
In the middle of the long floor near the pile of equipment was the plump form of Dr. Clef. He wore dark goggles over his eyes. A snarl of cables connected the central turbine’s generator to the machinery, and a smell of solder in the air said Dr. Clef had been welding. He looked up and pulled his goggles off when Alice shoved the door open. His face burst into a cheerful grin.
“I thought you all might arrive soon,” he called over the turbine whine. “And you brought my clicky kitty. So kind of you.”
“Doctor, you have to stop,” Gavin called back. “You don’t want to do this.”
He looked genuinely perplexed. “But I’m doing this for you, my boy. Everything is calculated and calibrated. In a moment, you’ll have all the time in the universe. You can save the world at last.”
Before any of them could respond to this, or even move, Dr. Clef threw a switch. The whine increased, and power snaked up the cable, through the machinery, and into the delicate arc. All the turbines slowed as the generators engaged and the arc drained their power. The arc glowed an electric blue, and the space within filled with light, first red, then orange, then yellow, green, blue, indigo, and violet. Gavin’s mind flicked back to a moment in the stone corridors beneath the Third Ward, a moment when he dropped the Impossible Cube and it changed colors as it fell in exactly the reverse order he was seeing now.
“Don’t!” Alice cried. She ran toward him. Gavin grabbed Feng’s arm and ran as well, though they were a good hundred feet away. Dr. Clef smiled beatifically and struck a large tuning fork on the table. A pure A rang through the room, and Gavin remembered that he had sung that same note in the same octave on the night he had caressed Alice with his voice and made the Cube vanish in the Doomsday Vault. It was the same note Dr. Clef had struck the day he had completed the Impossible Cube in his laboratory at the Third Ward and accidentally made the Cube disappear through time. Gavin had struck the fork again to bring the Cube back. A. The first note. The pure tone that rang through time and space and called the Cube to itself.
Dr. Clef pressed the handle of the fork to the arc, and the arc’s light became a white so beautiful, it made Gavin’s heart ache. They weren’t even halfway to him when Dr. Clef reached into the opening. It snapped and growled as it swallowed his hand. Gavin stared in fascination even as horror crawled over his skin. His steps faltered. The machines were hypnotic, thrilling. He was watching the most brilliant clockworker the world had ever seen bend time itself to his will with a unique machine. He was also watching the most powerful act of destruction in the history of the universe.
“He cannot.” Feng tugged at his arm now, trying to hurry him forward. “He will not.”
Dr. Clef whipped his hand out of the arc. The metal glowed bright as the sun. Alice, who was several paces ahead of Gavin, stopped in her tracks and threw up her arm to protect her eyes. Her little automatons squeaked in fear, and Click hissed. The glow faded a little, and when Gavin’s vision cleared, he saw Dr. Clef was holding the Impossible Cube.
“Shit,” Gavin whispered.
“My Cube,” Dr. Clef crooned. “
The Cube was just as Gavin remembered it. It was only the size of a hatbox, but its intricate metal lattice twisted the eye. The back seemed to shift to the front, or perhaps the front was fading into the back. One of the bottom struts crossed impossibly over the top. It shouldn’t have existed, but it did. Behind it, the arc continued to glow with holy fire.
Gavin shook off the fascination and started forward again with Feng. Alice did the same. He was in a dream, running through tar and molasses. Dr. Clef popped a pair of protectors over his ears and flipped another switch. The paradox generator atop the arc cranked to life, and the double tritone rippled through the chamber like demons and angels at war, amplified by the arc’s power so that the noise was clear even over the turbine whine. Gavin dropped to his knees at the terrible perfection of it.
Alice and Feng kept running. They had nearly reached Dr. Clef’s table, with Click and Alice’s automatons following in an angry brass cloud. Gavin admired her determination and tenacity, her beauty and power. Dr. Clef picked up another fork, and the small part of Gavin’s brain that wasn’t enthralled by the perfect, rapturous sound of his own generator noted the length of the prongs. D-sharp. Alice gathered herself to leap at him.
“
“I’m fine!” she gasped. “Stop him!”
“Help her, Feng,” Gavin said. “Help us! Do whatever it takes to help!” And without waiting for an answer, he ran toward Dr. Clef’s table. Another cable ran from the paradox generator. It ended in a clip that Dr. Clef was ready to connect to the Impossible Cube. But now Gavin was close enough. He raised his wristband, aimed fast, and fired. The cog spun through the air and knocked Dr. Clef’s hand aside. He yelped but didn’t drop the clip. The ringing in Gavin’s ears continued to muffle the tritones, though he heard enough for it to be a distraction.
Dr. Clef blinked at Gavin, who was already aiming another cog. There was only one left, and there was only one choice of what to do with it. Grimly, he cranked the magnetic power as high as it would go. Flung at full strength, a spinning cog would slice through flesh and bone like butter. Dr. Clef glanced at the wristband, his brilliant mind making instant connections, and Gavin saw the understanding in the eyes of his mentor, a man who, despite a few arguments, had never been anything but kind and helpful to Gavin, who wanted only to help him now. Gavin’s legs trembled, but his aim remained firm.
“You won’t,” Dr. Clef said, though Gavin was more reading his lips than hearing his voice.
“I have to,” Gavin said, and started to move his finger.
“I can show you your father,” Dr. Clef said.
Gavin froze.
