And he’d done it, he’d made it so. Told the stubby little principal to take the chains and padlocks he’d provided. She had followed his command, chained the exit doors, and then when a glimpse of defiance flashed in her beady little eyes, he promptly cuffed her with the late cue ball’s own official cop cuffs and commanded that she sit down, shut up, or get tarped. After that she was compliant, didn’t have the courage to look him in the eye.

“Listen up, toadstools! Anybody moves, I open fire, okay? And when the clip is empty, I detonate the bomb! Did I mention the bomb? No? Well, I got a bomb. And it’s really cool. Fifty pounds of C-4, which is enough to turn you all into jelly beans!”

Roland is unaware that with the music blasting, he’s shouting in a way that makes him sound like a raving madman. A babbling, out-of-control psycho. But that makes him all the more effective. None of his captives doubt that he will kill again at the slightest provocation.

“So stay in your seats!” he shouts. “Don’t move! You want to use your phones, make a few calls, go ahead! Let ’ em know I got it under control!”

He raises his other hand, showing off the Sony TV remote he has cleverly modified, guided by The Voice. “See this! It’s a detonator! Tell all your friends! Press this button, we all go boom!”

Roland and The Voice had debated the cell phone issue when the plan was being formulated. At first Roland thought he should confiscate all the phones, take control of communication, but The Voice reminded him how difficult that might be. Many of the teachers would have cells, a lot of the kids might have them stashed, and texting made it easy to send messages without being obvious. One man couldn’t search all those kids and teachers, not by himself, and the whole purpose of the plan was that he do it alone, his own personal one-man show. Thus proving that he was ready to move on to the next level.

So the idea was, embrace the captives’ ability to communicate with the outside world. No need for Roland to use his own cell, or share his own identifying vocal patterns with the authorities. Let little Kelly or Timmy make the call. That way he can concentrate on managing the situation, not get distracted by some dippy hostage negotiator. Excuse me, Mr. Penny, would you kindly step into our telescopic sights? No way. The Voice was right. Let the communication flow. Concentrate on the plan. Execute.

And whatever you do, don’t look at the tarp, or what seems to be flowing out from under it.

“People think I’m insane because I’m drowning all the time!” he shouts, unaware that he’s singing along with the heavy-metal lyrics pounding into his head. “Can you help me occupate my brain?” he screams. “Oh yeah!”

He’s right. Everybody in the gymnasium, students and teachers, and staff, they all think he’s totally insane.

Noah is pretty sure what it means to be turned into jelly beans. That’s what happens when a bomb goes off. You get blown into pieces no bigger than jelly beans. Not that he intends to explain it to the other kids, many of whom are confused about what the crazy bad man said. Jelly beans? Is the bad man going to give us candy?

Noah is not even slightly confused by what has happened. He gets it. He understands that none of this is pretend. The bad man is not a funny clown; he’s a killer. It’s all very real. The bad man really shot the white-gloved policeman and then quickly covered the body with a blue tarp. The bad man made Mrs. K lock the exit doors, weaving bright new chains through the push bars. The bad man keeps waving his ugly black gun, alternating between making threats and singing along with his stupid iPod.

One other thing Noah understands. The crazy bad man is getting worse, more crazy. He’s shouting things about Satan being inside his brain. He’s raging about cell phones, and the importance of letting the whole world know what’s going on, and some of the other kids are madly texting, as if the act of communicating what the bad man says will save them. Noah isn’t so sure about that. He thinks the bad man might really do it. He might press the button and turn them all into sticky red jelly beans. Then all of them would go to heaven-or not-Noah hasn’t decided yet about heaven, whether it really exists or whether it’s like Santa Claus, to make people feel better. He likes to think of his father as being in heaven, but if his dad was really in a place like that, wouldn’t he find some way to let his son know? Unless there are rules, and Noah supposes there might be, rules about not talking to those left behind. Rules as complicated and hard as calculus. He knows calculus exists because Mrs. Delancey has a book about it in her desk and Noah sneaked a look, and to his surprise could not immediately understand the contents. Whatever it is, calculus is more than arithmetic, more than algebra, more than geometry-it’s all of them mashed together, making something completely different, but at the same time tantalizingly familiar. Differentials? What are those? The formulas and symbols looked intriguing, as if they might contain all the answers about everything there is to know, including whether heaven really exists.

More than anything else, Noah wants to live long enough to understand calculus, and have his mom read him a bedtime story, and get up and have breakfast, and go to school as if nothing bad had ever happened. So he’s thinking really hard about what to do. How to get away without being turned into jelly beans, or doing something that will turn Mrs. Delancey into jelly beans.

Meanwhile the bad man rages at them.

“I see a black moon rising and it’s calling out my name!” he shouts, bobbing his head and pretending to strum an air guitar like on Guitar Hero. Then the bad man seems to correct himself, like a funny skip on a DVD. “Text the world, I want to get off! They’ll be coming round the mountain, boys and girls!” Then, shouting so loud he spits: “Don’t move! I swear to the prophet, I WILL BLOW THIS BITCH!”

Now he’s waving around the detonator button, pointing at it with his gun as he grins, showing all of his small yellow teeth. He holds the pose for a few beats, as if he knows that his picture is being captured on cells.

“Noah?”

Somehow Mrs. Delancey has slipped along the bench and is beside him, a comforting presence, a still point in the chaos of fear and confusion that radiates from everybody in the gym, including the bad man. She pitches her voice for him alone, her mouth a mere inch from his ear. “I want you to go and hide,” she whispers. “Hide in the air duct, Noah, like you did before. Can you do that for me?”

“I’m scared to move.”

She hugs him. At this moment, in this place, she smells like home. Like flowers and bread and home. And so he doesn’t want to leave her side. Doesn’t want to risk doing something wrong. Something that will make the bad man press his crazy button and send them all to heaven.

“Listen to me, Noah,” Mrs. Delancey says in her beautiful, lilting voice. “He’s not focused on anything but himself. All you have to do, slip down through the space between the benches, like you did before. He won’t be able to see you. Hide, Noah, please? For me? Hide in the air ducts, okay? I’ll come to find you when all this is over.”

“You promise?”

“I promise. Now go.”

As the bad man raises his fist, shaking the detonator and screaming something about children of the grave, Noah slips under the bench, through the narrow gap, into the stands. Into the familiar geometry of the supports and trusses that hold up the benches. The last time he did this, slipped away into the space under the stands during an assembly, he got in a lot of trouble. Mrs. K was really upset with him then, told him he might have been injured and nobody would have known where to look for him. Noah thought it was pretty funny, the way he’d run along under the benches, tugging at dangling feet to make the girls giggle and shriek. Mrs. K didn’t think it was funny at all and his mom had to come to the school and take him home. But that was last year. Things were different last year. He was younger then and he didn’t have Mrs. Delancey. Mrs. Delancey who understands him, and wants to save him.
