Only after that, very reluctantly, did I unlock the cuffs.

“You think this is all some kind of game, but it’s not,” I told her. “Your career decision probably cost some people their lives. Hope you get a promotion. Oh, yeah – and that you can live with yourself.”

As I drove away, I glanced in the rearview mirror and saw her still standing there on the curb, with her face in her hands.

Chapter 42

My new office at the Police Academy turned out to be a barely converted old locker room on the third floor, but who was complaining? Right off the top, I spotted two essential pieces of equipment, a folding table and a phone jack. There was even a touch of décor on the bulletin board – a hotel surveillance photo of the Teacher with sniper crosshairs drawn on his face.

We were in business.

After I called up McGinnis and apprised him of the latest developments, I rounded up my crew of detectives. I was pleased that Beth Peters was in the group. I asked her to make copies of the Teacher’s mission statement and pass them around.

“We need to get the airlines involved, Beth,” I told her. “Send them the surveillance photo and have them send us ID photos of their pilots for Mademoiselle Monchecourt to look through. Concentrate on the international carriers. British Airways in particular. Call up Tom Lamb at 26 Fed if you think you need some federal juice. And let’s try to track down the florist who sold that bouquet to our killer.”

“Oui, oui, boss man,” Beth said, batting her eyelashes teasingly.

I turned back to my group. “Now that it’s just cops here, maybe we can actually get something done,” I said, and started handing out specific tasks. I wasn’t used to being in charge and it felt weird, but they all hopped to it and seemed eager to do so. What a concept – people were actually doing what I asked. I decided I should try it at home.

I sent Nineteenth Precinct detectives back up to the Polo store and the 21 Club, to recanvass the areas with the photo and to interview all the employees they could find, including those that hadn’t been working on the day of the murder. Maybe the Teacher had been to those places before, and someone could match a name to his face.

But they called back in to say they’d come up empty at both places. Both institutions had plenty of disgruntled employees and nasty customers. Just none that fit the shooter’s description.

In the meantime, I checked downtown with Ballistics to see if the medical examiner had sent them the rounds that killed Officer Tonya Griffith.

“We got them, all right,” the senior tech, Terry Miller, said. “The twenty-two-caliber was mushroomed, but I could still make out the five lands, five grooves, and the left-hand twist to the barrel. It has the same markings as the bullet that killed the Twenty-one maître d’. I can pretty much ID it in my sleep by now.”

That was a strong point in our favor. The second we nailed this guy, we’d have evidence lined up and ready to go.

During the lulls when I didn’t have anything pressing to do, I sat and reread the manifesto that Cathy Calvin had given me. The penalty for obnoxiousness was now death? And I’d thought the nuns in grammar school were harsh. This guy might think of himself as the Teacher, but in truth, he was more like a vigilante.

What was it exactly that had set him off? The fact that some people had more money than he did? No, I realized. He hadn’t just picked his victims out of a hat. He must have had some previous contact with them in order to be offended to such an enraged degree. He had to have money himself.

I spent a lot of time looking at his picture, too. He definitely didn’t look like a mentally unbalanced, reclusive, on-the-fringe type like Berkowitz or the shooters at Columbine and Virginia Tech. He was smiling and seemed confident – was actually a strapping, handsome man.

I scratched at my developing five o’clock shadow.

What the hell was up with this guy?

Chapter 43

Around six P.M. I was alone in the office, with a newly installed computer. All the detectives were out on the bricks. I heard a tap at the door.

Damned if it wasn’t Cathy Calvin standing there, practically wringing her hands with nervousness.

“Must have taken a lot of investigative skill to find me here,” I said. “I’m impressed.”

“Quit it, Mike. Please? I came to – I won’t even say apologize, I know that’s no good.”

She was right, and I started to tell her so. But she actually seemed sincere. I noticed, too, that she’d changed out of her usual businesswoman combat uniform into a light, summery dress. It made her look softer, more feminine – really quite pretty.

“Just because I didn’t run you in doesn’t mean it’s finished,” I said. “The department’s going to be all over your editors.”

“They deserve it. I mean, I’m not just blaming them. I knew how wrong I was. It’s just? -” She stepped into the room, closing the door most of the way behind her. I could smell her perfume in the warm, still air. “This job makes you crazy,” she said. “The competition’s unbelievable. It’s turned me into a monster. When I started thinking about what I’d done, I just came apart.”

She drifted closer. It was clear that she wanted comforting, and I admit I was tempted to let her slip inside my arms and nestle her face against my chest.

But that temptation was easy to brush aside.

“My job hasn’t made me a nicer guy, either, Cathy,” I said. “But you’ve got to know where to draw the line – it goes with the turf. I figure when the day comes that I can’t find that line anymore, that’s the day I hand in my badge.”

My tone was no more inviting than my words. She stopped her approach.

“I’m leaving you a peace offering,” she said. She took an envelope out of her purse and dropped it on the table, then retreated to the door.

“Go ahead and hate me, Mike,” she said. “I just want you to know I’m really not like that. I’m not.”

Then she was gone.

Of course she wasn’t really like that, I thought. Not until the next time she stood to gain by it.

Inside the envelope was a copy of the Teacher’s original e-mail to her.

And on the bottom, he’d left her a Yahoo Instant Messaging ID where he could be contacted: TEECH1.

Through my clenched teeth, I called Calvin a bitch for not giving me this right away. Peace offering, my ass. Then I sat at my desk and tried to decide what to do with it.

Setting up a trace was difficult and complicated. In order to get the Internet company to assist, court orders would first have to be procured, and even then it could turn out that the message could have come from a public library or a college.

I made up my mind that we didn’t have time for that, and took a stab in the dark. Quickly, I created a Yahoo Instant Messaging ID for myself.

Then I sent a message to the Teacher.

MIKE10: Got your mission statement.

What happened next blew me away. After only a brief pause, an answer came back.

TEECH1: What did U think?

It was him!

MIKE10: Very interesting. Could we meet?

TEECH1: U R a cop aren’t U?

I debated lying, then decided against it. Treating the guy like he was stupid wouldn’t get us anywhere.

MIKE10: Yes. I’m a detective with the NYPD.

TEECH1: I didn’t mean to kill those cops, Mike. I like cops. They R among the few left in this world who actually believe in good and evil. But I needed to escape. What I’m doing is bigger even than the lives of 2 good people.

MIKE10: Maybe I could help U get your message across.

TEECH1: I’m doing just fine, Mike. Death and murder get people’s rapt attention. Their ears R perking up BIGTIME.
