The only way out was up.
She touched the cold, copper-plated wall. No handholds or crevices marred the surface. The exterior walls were too high to reach even if she stood on Books’s shoulders. The interior maze walls were a few feet lower. Maybe they could reach the top of them.
“Clackers run on treads; they’re not built for jumping,” Amaranthe said, “and these walls are too smooth for them to climb.”
“Yes, we share that problem.”
“Get on my shoulders.”
Amaranthe placed her palms against an inner wall and leaned toward it, feet planted. She bent her legs, so he could use her thigh as a step.
“You should go first,” Books said.
“I want you on top.”
“I don’t think I can-”
“Books, go!”
He approached her uncertainly. “You’re too small. I could hurt you. This is a bad idea.”
A clank echoed through the Maze. The clacker was near, no more than a couple corridors away.
“Good idea,” Books muttered. “This is a good idea.”
He stepped on her thigh, put a hand on her head, and pushed himself up. Amaranthe grunted as he clambered onto her shoulders. His boots ground into her muscles like a pestle working the bottom of a mortar. Once he was standing, she pushed her heels into the ground and, back rigid, inched up.
Heat rushed to her face, and her legs trembled. Sweat sprang from her skin.
“I can almost reach it,” he whispered.
A piece of wall detached to Amaranthe’s left. It pulled away from the main section and followed the tracks in the floor, eventually disappearing around a corner. Through the vacant orifice came an ominous rumble and the soft clacking of metal on metal.
Amaranthe pushed up to the balls of her feet.
“I think I can…” Books jumped off Amaranthe’s shoulders.
The force drove her to her knees, but Books grabbed the top of the wall first. Legs scrabbling against the smooth surface, he inched himself higher until he hooked his armpits over the edge. He swung his leg up and straddled the wall. Once he found his balance, he flattened onto his stomach and reached down to her.
“Hurry,” he whispered. “It just turned into the corridor over here. It seems to be finding us awfully quickly for some machine running on a random loop. “
A flaw in her plan presented itself. Books’s hand hung too far above to reach. Amaranthe tried to jump for it anyway-and missed by three feet.
Books’s eyes widened with distress. “That’s never going to work. You need to, ah, to…”
“Yes, professor?”
He pounded his fist against the wall. “I’m good in a classroom, I swear.”
“Don’t panic,” Amaranthe said. “I’ll think of something.” Yes, Amaranthe. Think of something. “What’s it doing?”
“It’s looking at me. Technically, I know it’s just a machine taking directions from a punchcard brain automated for a simple task. But I swear it’s looking at me. And it’s rubbing a pair of razor-edged pinchers together. Actually it’s clacking them. I suppose that’s where it derives its name.”
Brilliant analysis. Amaranthe kept the thought to herself. She was just as guilty of nervous rambling at times. She could not do so now though. One of them had to think of something. She looked around, seeking a tool to use, anything.
“Uh oh,” Books said.
“What now?”
“It says Tar-Mech on the back.”
“Larocka’s company?” Amaranthe asked.
“I think it heard you-it’s heading toward that gap in the wall.”
“It can’t hear me, Books. Let’s be logical here.”
“Maybe Mitsy bought an upgraded version with special features.”
Amaranthe froze, hands on the wall. “Like magic?” If Larocka could protect her home with it, what else might she be able to do?
“I don’t know, but it’s coming your way. You’ll be dead soon.”
“Thanks for the optimism.” Amaranthe looked down at her boots and her clothes. “Parka, of course.” She tore off the garment. “Catch the end.”
She swung it up. Books grabbed the hood and let the rest dangle.
“Brace yourself.” Amaranthe jumped and caught the bottom. The thick material supported her weight.
A huge blocky form rolled through the opening in the wall. Reminiscent of a giant beetle on treads, the metal creature had no head, but the back of its carapace reached seven feet. Two sets of arms extended from the front. The bottom ones were hooked, for grabbing. Above them, pinchers with three-foot blades snapped at the air. The clacker paused in the opening, like a wolf sniffing for a scent.
Hand over hand, Amaranthe pulled herself up the parka with new urgency. The smooth wall offered no purchase for her feet. Her arms and shoulders shuddered with the effort.
The clacker rolled toward her. Ten feet away. Five.
She reached for Books’s hand. Their section of the wall lurched into motion. It jarred her and she missed her target. Her knuckles cracked against metal.
The clacker’s pinchers extended toward her.
Books wriggled lower and grabbed Amaranthe’s wrist. He yanked her up.
His efforts tipped him off balance. Amaranthe hooked her arm over the top, and she in turn grabbed him to keep him from pitching backward.
The clacker rammed into the wall. Amaranthe hung on tightly. Metal shuddered, but the wall continued its ponderous route along the track.
She pulled herself the rest of the way up. Books righted himself, and they faced each other, straddling the six-inch wide perch. Amaranthe wiped her damp forehead with the back of her wrist.
The clacker rolled back and forth below, hissing steam and snapping its pinchers. It did seem rather peeved for a simple machine.
Books had managed to retain hold of Amaranthe’s parka, and he handed it to her. Out of immediate danger, he was noticeably calmer. “Now, I see why you had me go first. You wouldn’t have been able to pull me up.”
“I’d like to pretend my plan was that premeditated.” Amaranthe looked for Mitsy, but no one sat on the benches. She must be in her office. “I just wanted you off the ground because you seemed…”
“Distressed? Frantic?” Books grimaced. “Useless?”
Amaranthe hesitated, searching for something more tactful. He seemed to read the answer in her expression though.
“I’m sorry,” he said. “I’m not good in stressful circumstances. It was the same way when the enforcers came after me. A bunch of brutes with less intelligence than that thing-” he stabbed a finger toward the clacker, “-and all I could think to do was run. Pathetic.”
Amaranthe held back a comment about enforcer entrance exams ensuring there were no dumb brutes on the force and only said, “Composure during life-threatening situations takes practice.”
“Somehow, I suspect you were born with it.” Books studied his hands. Even now they gripped the wall with enough force to whiten his knuckles. “If the others ask about this, can we pretend it was the alcohol withdrawal that made me nervous?”
“I don’t see how our errand is any of their business.”
The creases at the corners of his eyes deepened as he smiled. “Indeed. Thank you.”
Their section of the wall clanked into a new home. Amaranthe repositioned her legs to turn around. Ahead of her, the route zigzagged but eventually met up with an exterior wall.
“Time to get out of here,” she said.
She and Books wiggled their way across the tops of the walls. The clacker trailed after them, like a dog still
