the tritone, spun him around, threatened to swallow him in the same way that infinite swallowed a whole number. He screamed and tried to shut the sound out, but his hands couldn’t quite mask it. Al-Noor writhed on the floor beside him, and Gavin was dimly aware that all the squid men had fallen to the floor as well.
And then the sound stopped. The pain ended, but the disorientation continued. Hands hauled him to his feet.
“How did you do that?” he gasped.
“I may not have perfect pitch,” Phipps said in his ear, “but after twenty-five years in the Third Ward, I can make a tritone with any note you-or Alice-can sing. Now, let’s get out of here before al-Noor and his squid men recover.”
“I’m so sorry we had to do that,” Alice said in his other ear as they stumbled toward the doorway. “Are you all right?”
“I–I think so.” Gavin shook off the disorientation and regained enough presence of mind to snatch up the Impossible Cube. It glowed pure azure, and it squirmed in his hands. The lattices twisted in ways he had never seen before, moving over and behind themselves, and his own hands seemed both close and far away at the same time. When he moved forward with Alice and Phipps, he could feel it tugging in his grip like a dog that wanted off its leash.
“The Cube,” he said. “It took in a lot of strange energy. I don’t know what that means.”
Phipps glanced back at the room. The squid men, who were plague zombies in their own way and who were also flattened by tritones, were stirring. Al-Noor was sitting up, his heavy belt askew and his black bathing costume torn. “Unless we want to kill them,” Phipps said, “we need to run now and worry about the Cube later.”
They ran. Phipps, whose monocle let her see best in the dim light, led the way. Alice noted the shattered doors they passed. “Good heavens, darling. Did you-?”
“Yeah.” The rage rose at the memory, and he forced it back down. “I’d do it again. Did he hurt you?”
“No, though he planned to. Your timing was perfect.”
The tunnel opened up into the enormous cavern. Most of the floor was taken up with the ocean, with a rim that ran around the edge. The
They hurried aboard the
“What is it doing?” Alice asked, unmooring the lines. Her little automatons streamed out of a hatchway to flitter and skitter in a brass cloud around her.
“No idea.” Gavin held up the Cube. The lattices slid and twisted around so fast, he couldn’t watch them. It was like looking at the sun. “It feels like it’s going to go off or something, but I don’t know what to do about it.”
“Are we cast off?” Phipps threw switches on the generator, and it rumbled to full power. Electricity scrambled up the wires to feed the endoskeleton, which came to blue life. Gavin set the Cube down and took the helm. The
“No!” Al-Noor was standing on the quay, alone. His cloak was missing, his hair rumpled, his silly swimsuit still torn. His belt was crooked. “Return at once! I will have the reward! I will!”
The rage threatened again, but Gavin still kept it under control. Al-Noor had no weapons in his hands and was no threat. The plague would kill him in a few months. No point in risking Alice’s life over further retaliation. Gavin spun the dial that cranked up the power to the nacelles and felt the
“What’s the bloody Cube
With the sound of a hundred waves rushing the shore, the giant squid rose from the water in front of the ship. Alice screamed. Phipps yelled. The squid reached for the
“Gavin!” Alice cried. “What are you-?”
Gavin sang one note, the first note that came to mind. It was the note Alice had sung back in al-Noor’s lair, a D-flat. Only later would he remember that he had also used a D-flat as the base for the paradox generator, which Dr. Clef had stolen and hooked to the Impossible Cube as part of his scheme to halt time. The Cube absorbed the clear tone and
Blackness engulfed Gavin, and for a horrible moment he was falling through ice water. Then the world exploded in a billion colors that pulled him downward into a pattern that became more complicated as he dropped toward it, the tiny particles themselves made of tiny particles made of tiny particles made of tiny particles. He shouted as he fell, not knowing if he would ever stop. He had no wings, no clothing, no body. He was nothing but a voice tumbling endlessly through chaotic patterns. The colors swarmed and drew together into a single pinpoint of light that exploded in all directions, and Gavin tried to hold his breath, but he could no longer breathe or move. Intense heat and brilliance flashed around him-
And then he was lying facedown on the hard deck of the
He pushed himself upright and immediately looked around for Alice. She lay curled on her side in a puddle of blue skirts with her mechanicals scattered around her. Phipps was on her hands and knees nearby, shaking her head. Gavin was about to run over to see to them when he remembered the squid. He tensed and glanced at the bow of the ship. Empty cavern, empty air. The squid was gone. Puzzled and relieved, he ran to the gunwale to make sure. The water beneath the ship lapped calmly at the stones. There was no sign of the giant squid, or even any indication that such a monster had ever existed. Behind the ship, the little quay was also empty. Al-Noor had disappeared as well.
Reassured but mystified, he hurried over to Alice and Phipps. Alice was already stirring, and he helped both women to their feet. The mechanicals came to life as well. The whirligigs started their propellers in short spurts and hovered uncertainly in the air while the spiders staggered about the deck like sailors on three-day leave.
“What in God’s name was that?” Phipps’s hair had come down completely, and she was trying to wind it back into a knot, but her hands, both metal and flesh, were shaking, and she wasn’t having much success.
Alice leaned on Gavin for a moment, and he could smell her hair. He allowed himself a moment to hold her, glad she was safe. Then she broke away from him and, as he had, ran to the gunwale to look around. Her mechanicals followed.
“They’re gone,” she said. “The squid, al-Noor-gone. I don’t see any squid men, either. What happened?”
The Impossible Cube was laying on the deck. Gavin picked it up. It felt heavier than usual. The glow had gone out, and the lattices, while still confusing, didn’t twist the eye nearly as much. It appeared to be nothing but an odd piece of machinery.
“Did the Cube destroy them?” Phipps conjectured.
“I’ve never seen it do anything like that,” Gavin replied, “though I don’t know half of what it can do. I can’t think of how it could destroy just al-Noor and his squid and leave us and the ship unharmed. And what were those lights about?”
“This isn’t the best place to have this discussion,” Alice said briskly. “Let’s leave, please.”
Phipps and Gavin agreed this would be a good idea. Under Gavin’s hand, the
