The first mailbox he passed had 201 printed on the side.

He figured the Skozie residence should only be two blocks away.

Kids were playing in the grass of a yard just ahead, taking turns running through a sprinkler. He tried to walk upright and steady as he reached their picket fence, but he couldn’t stop himself from favoring his right side to ease the jarring of his ribs.

The children became still and quiet as he drew near, watching him shuffle past with unrestrained stares—a mix of curiosity and distrust that made him uneasy.

He crossed another road, moving slower still up the next block as he passed under the branches of three enormous pines that overhung the street.

The numbers of the colorful Victorians that populated this block all started with a three.

Skozie’s block would be next.

His palms were beginning to sweat and the pulsing in the back of his head sounded like the thump-thump-thump of a bass drum buried deep underground.

Two seconds of double vision.

He squeezed his eyes shut tight, and when he opened them again, it had gone away.

At the next intersection, he stopped. His mouth had been dry, but now it turned to cotton. He was struggling to breathe, bile threatening to surge up his throat.

This will all make sense when you see his face.

It has to.

He made a tentative step out into the street.

Evening now, the chill coming off those mountains and settling down into the valley.

Alpenglow had given the rock surrounding Wayward Pines a pinkish tint, the same shade as the darkening sky. He tried to find it beautiful and moving, but the agony prevented this.

An older couple moved away from him, hand in hand, on a quiet stroll.

Otherwise, the street stood empty and silent, and the noise of the downtown had completely faded away.

He moved across the smooth, black asphalt and stepped onto the sidewalk.

The mailbox to 401 was straight ahead.

Number 403 next in line.

He was having to maintain a constant squint now to stave off the double vision and the stabbing throb of his migraine.

Fifteen painful steps, and he stood beside the black mailbox of 403.

SKOZIE

He stabilized his balance, holding fast to the sharp ends of the picket fence.

Reaching over, he unlatched the gate and pushed it with the tip of his scuffed, black shoe.

The hinges creaked as it swung open.

The gate banged softly into the fence.

The sidewalk was a patchwork of ancient brick, and it led to a covered front porch with a couple of rocking chairs separated by a small, wrought-iron table. The house itself was purple with green trim, and through the thin curtains, he could see lights on inside.

Just go. You have to know.

He stumbled toward the house.

Double vision shot through in nauseating flashes that he was fighting harder and harder to stop.

He stepped up onto the porch and reached out just in time to stop from falling, bracing himself against the door frame. His hands shook uncontrollably as he grabbed the knocker and lifted it off its brass plate.

He refused himself even a split second to reconsider.

Pounded the knocker four times into the plate.

It felt like someone was punching him in the back of the head every four seconds, and burning patches of darkness had begun to swarm his vision like miniature black holes.

On the other side of the door, he could hear a hardwood floor groaning under the weight of approaching footsteps.

His knees seemed to liquefy.

He hugged one of the posts that supported the porch’s roof for balance.

The wood door swung open, and a man who could’ve been his father’s age stared at him through the screened door. He was tall and thin, with a splash of gray hair on top, a white goatee, and microscopic red veins in his cheeks that suggested a lifetime of heavy drinking.

“Can I help you?” the man asked.

He straightened himself up, blinking hard through the migraine. It took everything in his power to stand without support.

“Are you Mack?” He could hear the fear in his voice, figured this man could too.

Hated himself for it.

The older man leaned in toward the screen to get a better look at the stranger on his porch.

“What can I do for you?”

“Are you Mack?”

“Yes.”

He edged closer, the older man coming into sharper focus, the sour sweetness of red wine on his breath.

“Do you know me?” he asked.

“Pardon?”

Now the fear was fermenting into rage.

“Do. You. Know. Me. Did you do this to me?”

The old man said, “I’ve never seen you before in my life.”

“Is that right?” His hands were balling involuntarily into fists. “Is there another Mack in this town?”

“Not that I’m aware of.” Mack pushed open the screen door, ventured a step out onto the porch. “Buddy, you don’t look so hot.”

“I don’t feel so hot.”

“What happened to you?”

“You tell me, Mack.”

A woman’s voice called out from somewhere in the house, “Honey? Everything OK?”

“Yes, Jane, all’s well!” Mack stared at him. “Why don’t you let me take you to the hospital? You’re injured. You need—”

“I’m not going anywhere with you.”

“Then why are you at my house?” A gruff edge had entered Mack’s voice. “I just offered to help you. You don’t want that, fine, but...”

Mack was still talking, but his words had begun to dissolve, drowned out by a noise building in the pit of his stomach like the roar of a freight train barreling toward him. The black holes were multiplying, the world beginning to spin. He simply wasn’t going to be able to stay on his feet another five seconds if his head didn’t explode first.

He looked up at Mack, the man’s mouth still moving, that freight train closing in with a vengeance of noise, its rhythm in lockstep with the brutal pounding in his head, and he couldn’t take his eyes off Mack’s mouth, the old man’s teeth—his synapses sparking, trying to connect, and the noise, God, the noise, and the throbbing—

He didn’t feel his knees give out.

Didn’t even register the backward stumble.

One second he was on the porch.

The next, the grass.

Flat on his back and his head reeling from a hard slam against the ground.

Mack hovering above him now, staring down at him, bent over with his hands on his knees and his words hopelessly lost to the train that was screaming through his head.

He was going to lose consciousness—he could feel it coming, seconds away—and he wanted it, wanted the pain to stop, but...

The answers.

They were right there.

So close.

It made no sense, but there was something about Mack’s mouth. His teeth. He couldn’t stop looking at them, and he didn’t know why, but it was all there.

An explanation.

Answers to everything.

And it occurred to him—stop fighting it.

Stop wanting it so badly.

Quit thinking.

Just let it come.

The     teeth     theteeth theteeththeteeththeteethteethteethteeth...

They aren’t teeth.

They’re a bright and shiny grille with the letters

stamped across the front.

Stallings, the man beside him in the front passenger seat doesn’t see what’s coming.

In the three-hour ride north out of Boise, it’s become apparent that Stallings adores the sound of his own voice, and he’s doing what he’s been doing the entire time—talking. He stopped listening an hour ago, when he discovered he could tune out completely as long as he interjected an “I hadn’t thought of it that way” or “Hmm, interesting” every five minutes or so.

He’s turned to make just such a token contribution to the conversation when he reads the word MACK several feet away on the other side of Stallings’s window.
