And he looks more than a little sexy in it.

What is it about men in tuxedos? Why do they always look so good in them? Maybe it’s the emphasis on the width of the chest and shoulders. Maybe it’s the startling contrast of crisp white shirt front and elegant black lapel.

Whatever it is, I don’t think I’ve ever seen a guy in a tux who didn’t look great. But Cooper is the exception. He doesn’t look great.

He looks fantastic.

I’m so busy admiring him that I nearly forget I’m attending this event to catch a killer. For a second—just one—I really do delude myself into thinking Cooper and I are on a date. Especially when he says, “You look great.”

Reality returns, though, when he looks at his watch and says distractedly, “Let’s go, all right? I’ve got to meet someone later, so if we’re going to do this, we need to get a move on.”

I feel a pang of disappointment. Meet someone? Who? Who does he have to meet? A client? A snitch?

Or a girlfriend?

“Heather?” Cooper raises his eyebrows. “You okay?”

“Fine,” I say, faintly.

“Good,” Cooper says, taking me by the elbow. “Let’s go.”

I follow him down the stairs and out the door, telling myself that I’m being an idiot. Again. So what if he has to meet someone later? What do I care? This isn’t a date. It isn’t. At least, not with him. If I have any kind of date at all tonight, it’s a date with the killer of Elizabeth Kellogg and Roberta Pace.

I repeat this to myself all the way through the park, past the Washington Square monument, and even as we cross the street to the library, where the event is being held and which has been transformed, by strategic placement of red carpets and colored lights and banners, into a ballroom for the occasion.

We have to dodge a few stretch limos and a bunch of uniformed campus security guards (Pete had been asked to pull a double for the occasion, but he’d said no, since his daughter Nancy had a science fair that night), all of whom wear white gloves and have whistles in their mouths, just to approach the massive, clay-colored building. There are velvet ropes to keep out the riffraff… only there doesn’t seem to be either riff or raff expressing much interest in crashing the party, just some graduate students standing there, clutching their backpacks, looking angry that the party is preventing them from getting to their study carrels.

Cooper shows his tickets to a guy by the door, and then we’re ushered inside and immediately assailed by waiters wanting to ply us with drinks and crab-stuffed mushroom caps. Which are actually quite tasty. The Oreos turn out not to be sitting very well beneath my control top panties, anyway.

Cooper snags two glasses for us—not of champagne, but of sparkling water.

“Never drink on the job,” he advises me.

I think about Nora Charles, and the five martinis she’d downed in The Thin Man, trying to keep up with Nick. Imagine how many murders he might have solved if he’d followed Cooper’s advice, and stayed sober!

“Here’s to homicide,” Cooper says, tapping the side of my glass with his. His blue eyes glint at me—almost taking my breath away, as always, with their brilliance.

“Cheers,” I reply, and sip, glancing around the wide room for faces I recognize.

There’s an orchestra playing a jazzed up version of “Moon River” over by the reference section. Banquet tables have been set up in front of the elevators, from which jumbo shrimp are disappearing at an alarming rate. People are milling around, looking unnaturally amused by each other’s conversation. I see Dr. Flynn speaking rapidly to the dean of undergraduates, a woman whose eyes are glazed over with either boredom or drink—it’s hard to tell which.

I spot a cluster of housing administrators bunched under a gold New York College banner, like a family of refugees at Ellis Island, huddled under the shadow of the Statue of Liberty. College administrators, I’ve noticed, don’t seem to be hugely respected by either the student body or the academic population. For the most part, the building directors at New York College seem to be viewed as little more than camp counselors, and Dr. Jessup and his team of coordinators and associate directors aren’t given much more respect than that. Which is unfair, because they—well, okay, we—work super hard—way harder than a lot of those professors, who breeze in to teach a one-hour class once a week, then spend the rest of their time backstabbing their colleagues in literary reviews.

While Cooper is being sucked into conversation with a trustee—an old Cartwright family friend—I study my supervisors over the rim of my glass. Dr. Jessup is looking uncomfortable in his tux. Standing beside him is a woman I take to be his statuesque wife, since she appears to be exchanging pleasantries with a woman who could only be Dr. Flynn’s better half. Both women look lean and lovely in sparkly sheath dresses.

But neither one of them looks as good as Rachel. Rachel stands beside Dr. Jessup, her eyes sparkling as brightly as champagne winking in the glass she holds. She looks resplendent in form-fitting silk. The midnight blue of her gown contrasts startlingly with her porcelain skin, which in turn seems to glow against the darkness of her hair, piled on top of her head with jeweled pins.

For someone who’d declared she’d had “nothing to wear” to the ball, Rachel had done really well for herself.

So well, in fact, that I can’t help feeling sort of self-conscious about the way I’m kind of spilling out of Patty’s dress. And not in a good way, either.

It takes me a while to locate the college’s illustrious leader, but I finally spot him over by one of the library check-out kiosks. President Allington has ditched the tank top for once, which might be part of the reason it takes me so long to find him. He’s actually wearing a tuxedo, and looks surprisingly distinguished in it.

Too bad I can’t say the same for poor Mrs. Allington, in her black velour, bell-bottomed pantsuit. Its wide sleeves fall back every time she lifts a glass to her mouth… which I must say she’s doing with alarming alacrity.

But where, I wonder, is the Allingtons’ progeny, the suave Chris/Todd/Mark? I don’t see him anywhere, though I’d been positive he’d show up, being a cute guy in his twenties, and all. What cute guy in his twenties can resist an event like this one? I mean, come on. Free beer?

Cooper is talking about lipstick cameras or something with an older gentleman who called me “miss” and said he liked my dress (in so sincere a tone that I looked down to make sure the zipper is still holding) when suddenly a very slender, very attractive woman dressed all in black walks up and says Cooper’s name in a very surprised voice.

“Cooper?” The woman, who manages to look glamorous and professorial at the same time, takes his arm in an unmistakably territorial manner—as if in the past, she’s touched him in other, more intimate places, and has every right to grab his arm—and says, “What are you doing here? It seems like it’s been months since I last heard from you. Where have you been keeping yourself?”

I can’t say Cooper looks panic-stricken, exactly.

But he does look a little like a guy who is wishing very hard that he were somewhere else.

“Marian,” he says, placing a hand on her back and leaning down to kiss her. On the cheek. “Nice to see you.” Then he makes introductions, first to the old guy, then to me. “Heather, this is Professor Marian Braithwaite. Marian teaches art history. Marian, this is Heather Wells. She works here at New York College as well.”

Marian reaches out and shakes my hand. Her fingers flutter like a tiny bird trapped between my own gargantuan mitts. In spite of this, I’m willing to bet she works out regularly at the college gym. Also that she’s a showerer, and not a bather. She just has the look.

“Really?” Marian says, brightly, smiling her perfect Isabella Rossellini smile. “What do you teach?”

“Um,” I say, wishing someone would shove a potted geranium on my head and spare me from having to reply. Sadly, no one does. “Nothing, actually. I’m the assistant director of one of the undergraduate dormitories. I mean, residence halls.”

“Oh.” Marian’s perfect smile never wavers, but I can tell by the way she keeps looking at Cooper that all she wants to do is drag him away and rip all his clothes off, preferably with her teeth, and not stand around chatting with the assistant director of an undergraduate residence hall. I can’t say I really blame her, either. “How nice. So, Cooper, have you been out of town? You haven’t returned a single one of my calls… .”

I don’t get to hear the rest of what Marian is saying because suddenly my own arm is seized. Only when I turn to see who is doing the seizing, instead of an ex—which would, of course, have been impossible, mine being in the hospital—I find Rachel.

“Hello, Heather,” she cries. Twin spots of unnaturally bright color light her cheeks, and I realize that Rachel has been hitting the champagne. Hard. “I didn’t know you were coming tonight. How are you? And Jordan? I’ve been so worried about him. How is he?”

I realize, with a guilty start, that I hadn’t thought of Jordan all night. Not since I’d opened my door and laid eyes on Cooper, as a matter of fact. I stammer, “Um, he’s all right. Good condition, in fact. Expected to make a full recovery.”

“What a semester we’ve had, huh?” Rachel elbows me chummily. “You and I definitely need a few weeks’ vacation after all we’ve been through. I can’t believe it. Two deaths in two weeks!” She glances around, worried someone might have heard her, and lowers her voice. “I can’t believe it.”
