In Noah’s mind, prime numbers glow with a special kind of magic. Almost as though they’re alive. Alive not in the human way of being alive, of course, but in the way that certain numbers can have power. When he thinks of, say, 97, it seems to have a pulse. It’s bursting with self-importance-look at me!-as if it knows it can’t be divided. Because dividing by one doesn’t really count. That’s just a trick that makes calculations work, but everybody who understands knows that what makes prime numbers prime is that they can’t be cleanly or perfectly divided. They remain whole, invulnerable, no matter what you try and do to them. Primes are like Superman without the Kryptonite. Which is actually how Mrs. Delancey described them on the very first day of math, totally blowing him away. What an amazing concept!

Yesterday Mrs. Delancey gave him a special tutoring session during recess. Noah had not wanted to go out on the playground at that particular moment-it just didn’t feel right, he couldn’t explain why-and lovely Mrs. Delancey had opened up a high-school-level math book and explained about dihedral primes. Dihedrals are primes that remain prime when read upside down on a calculator. How cool is that! Mrs. Delancey knew all about dihedrals and even more amazing, she knew he’d understand, even though it was really advanced.

Noah, having stowed his backpack, sits at his desk, waiting for the class to be called to order. At the moment mayhem prevails. Children run wild. Not exactly wild, he decides, there is actually a sort of pattern emerging. His classmates are racing counterclockwise around and around the room, a sweaty centrifuge of fourth-grade energy, driven mostly by the Culpepper twins, Robby and Ronny, who have been selling their Ritalin to Derek Deely, a really scary fifth grader who supposedly bit off the finger of a gym instructor in Rochester, where he used to go to school. Necessitating that his entire family escape to Humble, where they’re more or less in hiding. That’s what everybody says.

Noah finds it perfectly believable that a kid would bite off a teacher’s finger. He’s been tempted himself, more than once. Although that was mostly last year, when everybody thought that feeling sorry for him was the way to go. Like Ms. Kinnison always trying to hug him and ‘check on his feelings.’ Which really should be against the law, in Noah’s opinion. Feelings were personal and you weren’t obliged to share them with dim-witted adults who didn’t know the first thing about aerodynamics, momentum effects, or dead fathers.

“Take your seats! Two seconds!”

Mrs. Delancey hasn’t been in the room for a heartbeat and everything changes. Two seconds later every single child has plopped into the correct seat, as if by magic. As if Mrs. Delancey has waved a wand and made it so. While the truly magical thing is that she has no wand-Noah doesn’t believe in magic, not even slightly, not even in books-but has the ability to command their attention.

“Deep breaths everyone,” she instructs, inhaling by way of demonstration. “There. Are we good? Are we calm? Excellent!”

As Mrs. Delancey takes attendance, checking off their names against her master list, Noah decides that she is the living equivalent of a human prime number. Indivisible, invulnerable. Superteacher without the Kryptonite.

The amazing thing, given his family background, is how normal Jed turned out. Okay, my late, great husband was brilliant-after he died, his coworkers kept saying he was some kind of genius, the smartest guy in the company-so maybe having a brilliant mind isn’t exactly normal, but in all the usual normal human ways Jed was normal. He loved me unconditionally and I loved him back the same way. We wanted to make a life together, raise children, do all the normal kinds of things that normal people do. And we did, so long as we both shall live.

Not that it wasn’t a challenge. And luck played a role, right from the start. It was luck that we ever met. Blame it on Chili’s. Jed was working his way through Rutgers-he’d already cut all ties with his family-slogging through four-hour shifts at a local Chili’s three days a week and full-time-often twelve hours per shift-on weekends. Forty hours busing tables, thirty hours in lecture halls and labs, another thirty hitting the books-it didn’t leave much time left over for things like sleeping, let alone meeting mall girls from South Orange who just happen to be at a Chili’s celebrating a friend’s birthday, downing way too many Grand Patrón margaritas. Mall girls who get whoopsy drunk and barf in a tub of dirty dishes. Mall girls who are then so humiliated they burst into tears and cry inconsolably.

Well, not inconsolably. I wasn’t so drunk I didn’t have the presence of mind to take the dampened napkins the hunky busboy provided to clean up with, or let him walk me outside so I could get some fresh air. He was so sweet and kind, and so careful not to put his hands on me, even though I could tell he wanted to. And when I came back the next evening, cold sober, to formally apologize, we sat down and had a coffee and by the time we stood up I knew he was the man for me. The very one in the whole wide world. All the other boys-hey, I was a hot little mall girl-all the others were instantly erased, gone as if they’d never existed. My heart beat Jedediah, and it still does.

Jedediah, Jedediah, can’t you hear it?

After dropping Noah off at school I stop by the Humble Mart Convenience Store for a loaf of bread and some deli items-the selection is limited but of good quality-but mostly to hear the latest gossip being shared by Donald Brewster, the owner/manager. Called ‘Donnie Boy’ by everyone in town, which dates from his days as a high school football hero. Donnie Boy Brewster keeps a glossy team photo up behind the deli counter, blown up to poster size. When the customers mention it, and they do so frequently, Donnie Boy rolls his eyes and chuckles good-humoredly and says who is that kid? What happened to him, eh?

The ‘eh’ being the funny little Canadian echo some of the locals have, from living so close to the border.

Anyhow, Donnie Boy is one of the nice ones, a local kid who made good by staying local. He obviously loves his store, keeps it spiffy clean and well stocked, and he knows everything that’s going on in the little village of Humble and, best part, loves to share. Even with recent immigrants like me.

“Hey, Mrs. Corbin!”

I’ve given up trying to get him to call me Haley. All of his customers are Mister, Missus, or Miz, no exceptions. On the street he’ll call me Haley, but when he’s on the service side of the counter, I remain Mrs. Corbin. Donnie Boy’s rules.

Donnie in his little white butcher’s cap and his long bulbous nose and radar scoop ears, going, “We’ve got that Swiss you like. No pressure.”

“No, no, give me a quarter. It’s Noah’s favorite.”

“Coming right up,” he says, placing the cylinder of cheese in the slicing machine. “Thin, right?”

“Thin but not too thin.”

“Not so thin you can read through it. Got it. D’ja hear about the dump snoozer?”

Why I come here, to hear about mysterious local events like dump snoozing.

“Old Pete Conrad. You know, out Basel Road? The farmhouse with the leaning tower of silo?”

Happily, I am indeed familiar with the ‘leaning tower of silo.’ Nice old farmstead, with the main house kept up and painted and all the other buildings, barns and sheds in a state of disrepair, including a faded blue silo that’s seriously out of plumb. I don’t know Mr. Conrad personally, but have seen him at a distance, fussing at an ancient tractor.

“Pete’s out the dump-excuse me, the recycle center-in that old Ford, and it’s parked there most of the day before anyone notices Pete’s not in the freebie barn, which is where he usually hangs out. They’re about to lock the gate when somebody thinks to check his truck, and there’s Pete, lying on his side, obviously dead.”
