Gavin’s note faded. Alice drifted to the floor, her eyes wide. The glow faded from the Impossible Cube, and Gavin dropped it. As the cube tumbled toward the floor, it changed colors-blue to green to yellow to orange to red. The moment it touched the flagstones, red energy exploded in all directions with a bone-jarring whump and a blast of warm air that stirred hair and clothes. The cube was gone.
“Good Lord,” said Edwina.
Alice touched Gavin’s face. “Are you all right?”
He put his palm on her hand, unable to do anything but nod. Then all the strength left him. His knees buckled, and only Kemp’s chilly hands stopped him from dropping to the floor.
“Gavin!” Alice grabbed for him as well.
“I’m. . all right.” His voice was scratchy, and he managed to regain his feet. “Thank you, Alice. For bringing me out of that.”
She wrapped her arms hard around him, her face wet with tears. “You’re thanking me? God, Gavin. I love you always.”
“I love you always.”
“Heavens, I am good.” Edwina emerged from the workroom carrying a spider with a large clock built into its belly. “Except for this little toy. Do you know they wouldn’t give me the parts I needed to complete-ah! Just the thing.”
She set the spider down and plucked the whirligig automaton from Alice’s shoulder. It squeaked in surprise, and before Alice or Gavin could respond, Edwina tore open its access hatch and yanked out several bits of machinery. The little automaton quivered and went still. Gavin stared in horror.
“Edwina!” Alice cried. “What-?”
“Shush, dear. Auntie’s working.” With dazzlingly fast movements, she worked the machine parts-memory wheels, Gavin now remembered-into the clock spider’s insides and closed it up. Then she unceremoniously kicked the thing back into her cell and swept the bits of the whirligig aside with her foot. The entire affair took only a few seconds.
“Ready now, darlings!”
“What was that for?” Alice demanded.
“My final project. You wouldn’t expect me to leave it uncompleted, would you?”
“But-never mind. We have to get out of here. The noise will bring dozens of people down. Do you have the other cure?”
“I do,” Edwina said. “Let’s-oh dear.”
Some of Gavin’s strength had returned, and he straightened enough to glance around. The other doors in the hallway had also been destroyed, flattened by Gavin’s voice. Startled faces, male and female, young and old, were peeping into the corridor. Dr. Clef waved to Gavin.
“We should leave now,” Edwina said. “In fact, we should run.”
They sprinted up the stairs. At the top, they met a group of workers, none of them agents.
“What’s going on?” someone shouted.
“There was an explosion in the clockworker laboratories,” Alice said. “People need help! Hurry!”
“Halt right there!” barked a new voice. Lieutenant Phipps strode purposefully, if a bit unsteadily, around the lower turn in the spiral staircase. “It’s a trick. They’ve incapacitated all our agents and broken into the Doomsday Vault.”
Fear rushed down Gavin’s spine. He glanced at the dozen-odd workers, then at Phipps. Her face was pale and grim.
“Do you think this is the first time a cure has been found and repressed?” Phipps said quietly. “You walked right past three others in the Doomsday Vault. I won’t let you release any of them.”
“I never understood you, Susan,” Edwina said. “Even in school, you contradicted yourself. You push the Hats-On Committee into sedition, but balk at this?”
“I won’t commit treason,” Phipps said. She was bracing herself against the wall for support.
“I left you a present in my cell,” Edwina told her. “My final project. In fact-”
“You have ten minutes to evacuate,” boomed Edwina’s voice from below. Gavin’s blood ran cold. It was exactly the voice he’d heard in that terrible tower all those months ago.
“Good God,” Alice gasped. “The clock spider.”
“You can arrest us,” Edwina said, “or you can get all those unconscious agents to safety. You can’t do both.”
“For the good of the Crown,” Phipps replied hoarsely, “I’ll make the sacrifice.”
“But will they?” Edwina cocked a thumb at the workers.
“You have nine minutes and thirty seconds to evacuate.”
“I couldn’t have said it better myself,” Edwina said.
There was a moment’s hesitation. Then most of the workers swarmed around the group and out of sight down the stairs to help the agents. The remainder fled outright, leaving Alice, Gavin, Edwina, Kemp, and Click alone with Susan Phipps.
“Five against one, if you count the cat,” Edwina said. “And you’re still groggy. You can fight and lose, or you can run downstairs and save some lives.”
Phipps stared at them for a hard moment. Her eyes met Gavin’s, and the disappointment in her gaze nearly pushed him through the floor. Then Susan Phipps turned and marched down the steps.
Outside, they ran toward the barn with Click leading the way. Kemp and Gavin slid the huge doors open while Alice, Edwina, and Click rushed up the gangplank onto the little airship. When Alice arrived, more than a dozen little automatons poured out of a hatchway and surrounded Alice like a cloud of metal fairies. They squeaked with joy.
“And I’m glad to see you,” she said, “but we have no time. Cast off!”
The whirligigs and spiders scampered to obey while Edwina glanced around long enough for her plague-enhanced mind to figure out how everything worked. She cranked the generator, which coughed to life in a cloud of paraffin smoke, and pale blue energy crawled up to the envelope, where it swirled and swooped in a fine glowing pattern beneath the skin. The light revealed words painted along the gunwale. Alice read them aloud as Gavin ran up the gangplank with Kemp close behind.
“The Lady of Liberty,” Alice said with tears in her voice. “Oh, Gavin!”
Gavin grinned and flipped switches. The propellers buzzed to life while Kemp reached for the gangplank.
“Wait for me! Wait!” Gabriel Stark, known as Dr. Clef, puffed up the plank and onto the ship. He was carrying a large lumpy sack. “Du Lieber. How could you leave me behind to explode? And where is my Impossible Cube?”
“Er,” Alice said. “I’m not sure how to-”
“Oh-you have a clockwork cat. That is very nice. I will forgive you if I may pet the cat.”
“Be my guest,” said Edwina.
The airship, meanwhile, moved, gliding gracefully out the wide doors into the open air.
“It flies! Gavin. It flies!” Alice clapped her hands with joy, and Gavin’s grin widened into exultation.
“She flies,” he said.
“So this is what for you wanted all my alloy,” Dr. Clef exclaimed. “Never would I have thought of this application. Very intelligent.”
“You have four minutes to evacuate.” Edwina’s voice was clear, even outside. People streamed from the house like ants from a hill.
“Why don’t they just take the bomb outside?” Alice asked.
“They can’t, darling,” Edwina told her. “The spider grabs the floor, you see, and it’s too complex for anyone but a plague genius to deactivate, and then only with days of study.”
The airship coasted past the chaos a bare six feet above the ground. No one seemed to notice them-everyone was busy dragging unconscious agents out of the house.
“You intended to destroy the Ward from the very start, didn’t you?” Alice said tightly to Edwina.
“Well, obviously. Look what they’ve done to us. To you. That device will make the one at my country house look like a mousetrap, so let’s move along, please.”
“I don’t see Simon or Glenda or Lieutenant Phipps,” Gavin said. He felt sick. “They won’t make it out.”
