The Teacher shook away the reverie and tucked the Treo safely back into his fanny pack. He stood, spent a moment stretching, then lowered himself to a runner’s on-your-mark stance, fingers digging into the gravel path.

He had his game face on now. It was time to get to work.

Bang! went an imaginary starting pistol in his head.

With his strong legs churning and gravel flying behind him, he bolted into a sprint.

Step one of the plan was to create a smoke screen. The Teacher was racing along the pavement between 41st and 40th when he spotted a perfect opportunity – a middle-aged businessman jaywalking across Sixth Avenue.

Strike like a cobra, he thought, instantly changing the course of his pounding footsteps.

He crashed into the suit like a linebacker, catching him in a headlock and dragging him to the curb.

“Hey! What the hell?” the guy gasped, struggling feebly.

“Cross on the green, not in between,” the Teacher sang, and spilled him to the pavement. “Like a human being – not a worthless animal.”

He spun away, and within seconds he was back at full speed, arms pumping, alert for his next target. He spotted it in an Asian restaurant deliveryman who was rushing south down the opposite sidewalk, jostling other pedestrians as he wove in and out of the crowd.

The Teacher made another instant turn, dashing out in front of the oncoming traffic and across the street, accompanied by a symphony of blaring horns, screeching brakes, and shouted curses.

Take-out food bags flew into the air like startled pigeons as he clotheslined the deliveryman with a forearm across the throat.

“Where’s the fire, buddy?” the Teacher roared. “This is a sidewalk, not a racetrack. Show some fucking courtesy, you got me?”

He took off again, his flying feet barely touching the pavement. He felt incredible, invincible. He could run straight up the fronts of the glass canyon office towers and down the backs of them. He could run forever.

“WE WILL, WE WILL, ROCK YOU!” he screamed into startled faces. He’d always hated that song, but damn if it didn’t feel spot-on right now.

People stopped and stared. The street-smart ones, hot dog vendors and waiting radio car drivers and bike messengers, were wisely getting the hell out of his way.

It was hard to rouse attention on the jaded streets of Manhattan, but he was doing a bang-up job.

The light bouncing off the dark glass curtains of the monstrous buildings poured down on him like a holy baptism. His face split into a huge grin, and his eyes filled with happy tears.

He was actually doing it. After all the planning, all the obstacles, it was showtime.

He jumped out into the curb lane of the wide avenue and sprinted full bore toward the trees of Central Park.

Twenty minutes later, the Teacher emerged from Central Park on the Upper East Side. Though he’d run more than thirty blocks, he hardly noticed it. He wasn’t even winded. He raced out across tony Fifth Avenue and kept going east down 72nd.

Then he finally slowed to a halt, in front of a fabulously ornate four-story French château-style building on the southeast corner of 72nd and Madison – the flagship Ralph Lauren store.

The first target that really counted.

The Teacher glanced at his watch to make sure he was still on schedule, then took a long look up and down both the side street and the avenue. There were no cops in sight, which wasn’t surprising. This store sat smack-dab in the middle of the city’s most populated precinct. Roughly fifty officers, probably fewer counting sick days and vacation, were supposed to protect more than two hundred thousand people. Good luck, the Teacher thought. He pulled open the store’s shining brass door and stepped inside.

He gazed around, taking in the Persian rugs, chandeliers, and oil paintings on the fifteen-foot mahogany-paneled walls. Not exactly your local Kmart. Among the antiques and flower arrangements, piles of cashmere cable knits and oxford-cloth button-downs were distributed with artful casualness. The overall impression was that you’d walked in and caught the Vanderbilts unpacking from a summer in Europe.

In other words, it was disgusting. He jogged up the wide mahogany stairs to the men’s shop.

A slick-haired man in an impeccably tailored three-piece suit stood behind an antique glass display case filled with neckties. One of his eyebrows rose just enough to signify his contempt for the slovenly buffoon he saw approaching.

“May I help you?” he said with a condescension that bordered on vicious. The Teacher knew that if he answered “yes,” the salesman would laugh out loud.

So he just smiled.

“Are we a trifle language-challenged, sir?” the malicious bastard crooned. Then he dropped the polished pretense and spoke in much coarser, and much more natural-sounding, Brooklynese. “We’re all outta fanny packs today. Maybe you better go to Mo’s instead.”

The Teacher still didn’t speak. Instead, he unzipped the little pack and took out a pair of objects that looked like Cheez Doodles. They were actually firing-range earplugs. Without hurrying, he pressed one of them into his left ear.

The haberdasher started to look flustered, and took on his piss-elegant tone again.

“I beg your pardon, sir, I didn’t realize you needed hearing aids. Still, if you’re not here to purchase something, I’m afraid I’ll have to ask you to leave.”

The Teacher paused, with the second earplug still between his fingers, and finally spoke.

“I’m really here to give you a lesson,” he said.

“Give me a lesson?”

“In salesmanship,” the Teacher said, mimicking the prick’s supercilious tone. “You’ll be sew much more successful if you learn to treat all your customers with respect. Watch how it should be done.”

He pushed in the second earplug, then reached into the fanny pack again and drew out an oiled pistol.

“And here,” he said, with his words muffled in his own ears, “we have the Colt M1911 semiautomatic in.45 caliber. Would you care to try it, sir? I dew believe you’ll be impressed by its performance.” He flicked off the safety and put the hammer on full cock.

The clerk’s mouth opened in an O. His lips moved as he stammered words that the Teacher could barely hear. “Oh, my God… terribly s-sorry…” One soft, manicured hand flew to the cash register and punched open the drawer. “Please, take everything…”

But his other hand moved, too, dropping under the counter, no doubt to reach for a hidden alarm button.

The Teacher was expecting that. His finger twitched, and the first big.45-caliber round boomed like a stick of dynamite, blowing the display case into a cymbal crash of shattering glass. The clerk screamed, staggering backward, clutching at his mangled, bloody hand.

“I’m not here to take,” the Teacher said quietly. “I’m here to give you something you’ve wanted your whole life, but were afraid to ask for.”

“Redemption.” He emptied the rest of the clip point-blank into the salesman’s chest.

Watching him careen backward, limbs flopping spastically like he’d been hit by a giant sledgehammer, was the most electrically satisfying moment of the Teacher’s life.

There were going to be more of those soon.

He reloaded the Colt with smooth, practiced motions as he hurried back down the steps. As he got to the door, he noticed another suave clerk, crouched beside a cashmere upholstered club chair. This man was shivering in shock, too terrified even to scream for help.

The Teacher paused long enough to press the Colt’s barrel against his cheek. Then he spun the big gun off his finger, caught it in the air, and stuffed it back into his fanny pack.

“You are the witness to history,” the Teacher said, patting the sniveling fop on the head. “I envy you.”
