And okay, my conviction that girls don’t elevator surf—particularly preppie, Ziggy-loving girls—may not be what anyone could call rock-solid proof. But what about the missing key? What about THAT?

Except that, as I flip to the rack that normally holds the elevator door key, I see something that makes my blood run cold.

Because there, in the exact place it’s supposed to go—the exact place it wasn’t, just moments ago—is the elevator door key.

He says he’ll be here in five minutes, but he’s in the lobby in less than three.

He’s never been inside the building before, and looks strangely out of place in it… maybe because he isn’t tattooed or pierced like everyone else who passes by the desk.

Or maybe it’s just because he’s so much better-looking than everybody else, standing there with his bed-rumpled hair (although I know he’s been up for hours—he runs in the morning) and his banged-up leather jacket and jeans.

“Hey,” he says when he sees me.

“Hey.” I try to smile, but it’s impossible, so I settle for saying, instead, “Thanks for coming.”

“No problem,” he says, glancing over to the TV lounge, just outside the cafeteria door, where Rachel, who’d been joined by an ashen-faced Dr. Jessup, along with a half-dozen panicked residence hall staffers, are milling around, looking tight-faced and upset.

“Where’d the cops go?” he asks.

“They left,” I say, trying to keep the bitterness from my voice. “There’s been a triple stabbing in an apartment over a deli on Broadway. There’s just that one left, guarding the elevator shaft until the coroner can get here to take her away. Since they decided her death was accidental, I guess they figured there was no reason to stay.”

I think this is a very diplomatic response, considering what I want to say about Detective Canavan and his cronies.

“But you think they’re wrong,” Cooper says. A statement, not a question.

“Someone took that key, Coop,” I say. “And put it back when no one was looking. I’m not making it up. I’m not insane.”

Although, the way my voice rises on the word insane, that claim may actually be debatable.

But Cooper’s not here to debate it.

“I know,” he says gently. “I believe you. I’m here, aren’t I?”

“I know,” I say, regretting my outburst. “And thanks. Well. Let’s go.”

Cooper looks hesitant. “Wait. Go where?”

“Roberta’s room,” I say. I hold up the master key I’ve swiped from the key box. “I think we should check her room first.”

“For what?”

“I don’t know,” I say. “But we have to start somewhere.”

Cooper looks at the key, then back at me.

“I want you to know,” Cooper says, “that I think this is a bad idea.”

“I know,” I say. Because I do.

“So why are we doing it?”

I am about five seconds from bursting into tears. I’ve felt this way since Jessica first burst into my office with the news about another death, and my humiliation in front of Detective Canavan hasn’t helped the matter any.

But I struggle to keep the hysteria from my voice.

“Because this is happening in my building. It’s happening to my girls. And I want to be sure it’s happening the way these cops and everyone are saying it’s happening, and that it’s not… you know. What I’m thinking.”

“Heather,” he says. “Remember when ‘Sugar Rush’ first came out, and all that fan mail started arriving at the Cartwright Records offices, and you insisted on reading it all, and personally answering it?”

I bristle. I can’t help it.

“Hello,” I say. “I was fifteen.”

“It doesn’t matter,” Cooper says. “Because in fifteen years, you haven’t changed. You still feel personally responsible for every person with whom you come in contact—even people you’ve never met. Like the reason you were put on earth is to look out for everybody else on it.”

“That’s not true,” I say. “And it’s only beenthirteen years.”

“Heather,” he says, ignoring me. “Sometimes kids do stupid things. And then other kids, because they are, in fact, just kids, imitate them. And they die. It happens. It doesn’t mean a crime has been committed.”

“Yeah?” I am bristling more than ever. “What about the key? What about that?”

He still doesn’t look convinced.

“I want you to know,” he says, “that I’m only doing this to keep you from making an even bigger mess out of things than they’re already in—something, by the way, at which you seem to excel.”

“You know, Coop,” I say. “I appreciate that vote of confidence. I really do.”

“I just don’t want you to lose your day job,” he says. “I can’t afford to give you health benefits on top of room and board.”

“Thanks,” I say snarkily. “Thanks so much.”

But it doesn’t matter. Because he comes with me.

It’s a long, long walk up to Roberta Pace’s room at the sixteenth floor. We can’t, of course, take the elevator, because they’ve been shut down. The only sound I hear, when we finally reach the long, empty hallway, is the sound of our own breathing. Mine, in particular, is heavy.

Other than that, it’s quiet. Dead quiet. Then again, it’s before noon. Most of the residents—the ones who hadn’t been awakened by the ambulance and fire engine sirens—are still sleeping off last night’s beer.

I point the way with my set of keys and start toward 1622. Cooper follows me, looking around at the posters on the hallway walls urging students to go to Health Services if they’re concerned that they might have contracted a sexually transmitted disease, or informing them of a free movie night over at the student center.

The RA on sixteen has this thing for Snoopy. Cut-out Snoopys are everywhere. There’s even this posterboard Snoopy holding a real little cardboard tray with an arrow pointing to it that says, “Free Condoms Courtesy of New York College Health Services: Hey, for $40,000 a year, students should get something free!”

The tray is, of course, empty.

On the door to 1622, there is a yellow memo board, the erasable kind, with nothing written on it. There’s also a Ziggy sticker.

But someone has given Ziggy a pierced nose and someone else has written in a balloon over Ziggy’s head, “Where Are My Pants?”

I raise my set of keys and bang on the door, hard, with them.

“Director’s Office,” I call. “Anybody there?”

There’s no response. I call out once more, then slide the key into the lock and open the door.

Inside, an electric fan on top of a chest of drawers hums noisily, in spite of the fact that the room, like all the rooms in Fischer Hall, has central air conditioning. Except for the fan, nothing else moves. There is no sign of Roberta’s roommate, who is going to be in for quite a shock when she gets back from wherever she’s gone, and finds herself with a single room for the rest of the year.

There’s only one window, six feet across and another five feet or so high, with twin cranks to open the panes. In the distance, past the garden rooftops and water towers, I can see the Hudson, flowing serenely along its way, the sun’s rays slanting off its mirrored surface.

Cooper’s squinting at some family photographs on one of the girls’ bedstands. He says, “The dead girl. What’s her name?”

“Roberta,” I say.

“Then this bed’s hers.” She’s had her name done in rainbow letters on a sheet of scroll paper by a street artist. It is hanging over the messier bed, the one by the window. Both beds have been slept in, and neither roommate appears to have been much concerned with housekeeping. The sheets are tousled and the coverlets—mismatched, as room mates’ coverlets so often are—are awry. There is a strong Ziggy motif in the decorating on Roberta’s side of the room. There are Ziggy Post-it Notes everywhere, and a Ziggy calendar on the wall, and on one of the desks, a set of Ziggy stationery.
