“What? Be quiet, I’m trying to think.”


“Lu, look at the floor. Lu, look at the floor!”


“I’m looking! I see it, okay? I see how the water’s coming up.”


A loud creak popped through the hideous white noise of the hammering rain.


Leslie jumped and scrambled higher, to stand just below her sister. “What was that?”


“How should I know? Stop it, you’re panicking. Don’t panic. It’s just water. It’s just water.”


“It’s a lot of water.”


“But we’re on top of all this stuff. We’re real high up. It won’t reach us. When it stops raining, it’ll all run back down to the river, that’s what it’ll do. It can’t rain forever. Maybe we’ll even find our bikes. Maybe Momma won’t kill us.”


“You’re going to be grounded until you’re dead.”


“Get on up here.”


Leslie squeaked with alarm, and pointed back at the ground.


“It’s still getting higher!”


“Well it’s not going to get as high as the roof or anything. There’s—there’s an attic, Shelly said. She went up there with a boy once, but don’t tell her I told you about it.”


“Which boy?”


“I don’t know. One of ‘em. Just, come on. We can climb across these, over to the other side—I think that’s it, that’s the attic door in the ceiling, see it?” They were both getting drenched, standing beside the open window. Lu took Leslie’s face in her hand and directed it to a handle above them, across the armory space.


“I see it. Yeah. We can make that, can’t we?”


“We can make it.” But the water was rising still, filling up the spaces between the cloaked machines. A foot at a time it crawled the walls, so fast that if Lu picked a spot on the wall to stare at, she could count to ten and watch it disappear. At the window the rain was finding easy entry, and the river was waiting its turn.


“This is bad, isn’t it?” Leslie fretted. She stood close to her sister and shivered.


“It’s not that bad. Here. Stretch your legs, you can make that next stack—see? Just crawl and be careful. You won’t fall. You go first. I’ll help you.”


“You go first.”


“All right. We’ll do it that way, then.” Lu reached out one long arm and snagged the tightly-fitted tarp on the next pile of junk over. By shifting her weight she closed the distance and grabbed a handful of canvas, using it to haul herself over. She extended her hand back to Leslie. “Here—come on. I’ll pull you.”


Leslie nodded and held out her hand. She let her sister heave her across, and when she arrived on the new spot, she clung to the heap and dug her fingers into its bulk. “Only one more, right?”


“Just one more. Then we’ll be right under the attic, and I’ll pull the door down so we can go up inside. It’ll be drier there. We’ll be safe for a long time. Long enough for the rain to stop and the water to go down, anyhow.”


“Okay. Okay. Don’t let go of my hand.”


“I’ve got to for a second. The next one’s closer, see?” Lu only leaned to reach the second stack of covered military detritus. She could span the gap between them if she stretched her legs apart, so she made herself a bridge and let the smaller girl scramble across her body. “Now give me your hand again.”


She didn’t need to ask twice. Leslie thrust her fingers into Lu’s. “I’m getting scared.”


“That’s okay. This is kind of scary. But don’t freak out on me. Freaking out only makes it worse.” Lu reached for the metal latch above her head and gave it a good yank. The ceiling held, and groaned.


“You’ll have to—Les, put your arms around my waist. Pick your feet up, yeah. Like that. I’m not heavy enough. Pick up your feet. There, that’s it.” Combined, their weight pulled against the springs and coils above, and the hatch reluctantly slumped down with a jerky flop. A ladder on a set of rollers followed it. Lu grabbed the bottom rung and pulled.


“It’s dirty up there.”


“It’s dirty and wet down here. Go on. I’ll hold the door down, you go up the steps.”


“You go first.”


“I can’t. You’re not heavy enough to hold the door down. Just go. I’m right behind you.”


“You better not be fooling me.”


“I’m not fooling you.” Lu’s arms shook as she held the door low enough for Leslie to scale. Beneath them, the water soaked its way up the veiled machines, rising foot by frightening foot. By Lu’s estimation, if they’d stayed on the floor it would have been up to her little sister’s waist; but she also knew that on the other side of the window, more water waited. The whole river was knocking, asking to come inside—and it had shown up quick on the doorstep. She’d sworn the flood wouldn’t make it to the armory’s old roof, but she wasn’t as sure as she pretended.


Later she would learn that a dam somewhere up river had failed, and that’s why the water had come so high, so fast. And later, it was easy to say that if she’d only known, she never would have brought her sister out to explore.


But back then, as the afternoon grew late and the sky went dark and the Tennessee River oozed up out of its bed, Lu could only work with the decisions she’d already made. She pushed at Leslie’s feet, then scurried up after her.


With the weight of the girls removed, the door clapped itself shut into the floor behind them.


“It’s dark up here,” Leslie whispered, because big, dark places made her think of church.


“You said it was dark down there.”


“Well, it’s even darker up here.”


“You’ll get used to it.”


The attic was as dirty as Leslie had declared, and darker than Lu was willing to admit. Rain noise was louder there too, since nothing but the thin metal roof separated the girls from the sky.


Lu peeled off her sweater and wrapped it around Leslie, who was wetter and colder, or so it seemed. “Don’t touch the pink stuff in the floor,” she said, pointing to the half-finished floors. “It’ll make you itch, or that’s what Shelly said. It’s insulation. Walk on the boards in between them, if you can.”


“Okay.” On shaky legs Leslie did as she was told, struggling to stand astride the beams that would hold her. “This sucks. We can balance up here above the itchy pink stuff, or balance down there above the water.”


Lu lifted her voice to be heard above the battering rain. “The pink stuff is warm, at least, and it won’t drown you if you sit in it too long. So I’ll take the pink stuff, if it’s all the same to you. Let’s go back there—the floor’s more covered. Less pink stuff to worry about.”


Together they tiptoed across the wood planks and dodged curtains of cobwebs, Leslie going first with Lu’s hands on her shoulders. If either of them had been any taller, they would’ve had to crouch. But as it was, both of them could lift their hands and brace themselves on the underside of the roof.


Leslie coughed and wiped at her face. “It smells gross up here.”


Down by one of Lu’s feet, curled in a pink, fluffy bed, the remains of a rat lay decomposing. “It’s just . . . old stuff. Old places. They smell like this, after a while. Don’t worry about it. Keep going.”


When they reached the back corner they sat down, curling their arms and legs until they folded around themselves, and around each other. “I’m cold,” Leslie complained, but Lu knew she was mostly just afraid and didn’t want to say so.


“Yeah, it’s chilly in here. But you’ll warm up as you dry off.”


Down came the rain and washed out all the other sounds except for the occasional cracking, creaking complaint of the old armory. But the armory was built to last. It would not fall, it would only fill.


Night settled in early because of the weather, and the rain kept coming.


Antsy and damp, the girls huddled close without speaking much. Once it was dark there was no sense in speaking. There was no reason to talk about heading home; the only real question was when to start shouting for help. The time hadn’t come quite yet—there was a balance that must be tipped. Their fear of their mother had to be outweighed by their fear of being trapped, and for a long time the fear of their mother won out.


Lu also thought that if they stayed missing long enough, there might be a chance that parental relief would be great enough to overrule parental retribution. Her hopes weren’t high, but she was running low on hope as the night dragged on, so she clung to what she could get.


Lulled by the violent downpour and its insistent beat on the metal roof, eventually the sisters dozed.


But they awoke with a jolt and grasped at each other’s arms.


“What was that noise?” Leslie demanded, though she knew her sister didn’t know any better than she did.


The noise sounded again and they were both awake enough to hear it clearly. It was something hard and knocking. Something dense and thick, with deliberate intent.


“Somebody’s there?” Lu guessed. “I don’t know. It sounds like . . .” She hesitated, listening hard.


There, again. Another blow. This one made their bottoms jump.


Leslie breathed faster. “Somebody’s right underneath us. I think.”


“Not somebody? Maybe something floating.” Lu knew as soon as she said it that she shouldn’t have.


“What? You think the water’s got that high?” There was the panic again. “Floating up so high that it hits against the ceiling underneath us? You don’t really think—”


Lu thought of the river outside the window, and how it boiled at the walls of the armory. She believed yes, that the water could get that high; and she figured that yes, something must be floating up to the ceiling in the hollow space below. But to say so meant that her sister must know it too; and though she was not such a nervous little sister as little sisters went, ten or twelve feet of water underfoot might be enough to send anybody into a fit.
