"That's how he took her down."

"Maced her and choked her," he said, "and then took her and drowned her. Must have been quick."

"And quiet."

"Well, it had to be quiet, with her roommates just a few yards away. Poor kid."

"She was on full scholarship," I said. "Taking a summer school course on the French Revolution."

"Maybe she had a classmate named Arden Brill. Wouldn't that be handy?"

But there was no Arden Brill. Wentworth called an hour later to tell me as much. There were no Brills at all registered at Columbia, none at NYU or CUNY or any other colleges he'd checked.

Phone directories for the city and the surrounding tristate area showed a fair number of Brills, about the same number proportionally as we'd found in the Manhattan book. None with Arden for a first name, though, and nothing close- no Alden, no Alton, no Auden. He had a couple of officers on the phones, working their way through the Brills, trying to find an Arden Brill. It was a thankless task, stupefyingly dull, and he didn't expect it to yield anything useful.

"He made up a name," he said, "and she passed it on, and got killed for it. It proves one thing, though it wouldn't prove it in court."

"Oh?"

"Proves you were right about the Hollanders. Case never should have been closed, though you can see why they closed it."

I asked if he was going to try to get it reopened.

"Call up somebody I don't know and tell him he fucked up? That's no way to win friends and influence people."

"It might help get police protection for Kristin Hollander."

"The cousin. You think she needs it?" He answered his own question. "Both parents and a cousin, I guess somebody ought to keep an eye on her. Reminds me, she's on my list of people I'd better talk to."

"Has she been notified?"

"Not by me. Next of kin's her mother, and nobody's been able to reach her yet. Roommate ID'd the body."

"I'll notify Kristin," I said, "and I'll tell her to expect to hear from you."

"Appreciate it."

"And not to open the door for anybody else."

"I'll make sure I'm the one contacts her," he said. "And as far as reopening the case, for now all I want to concentrate on is getting this guy. Once he's good for Parkman, we can add the Hollanders to his tab."

"Plus two in Brooklyn."

"Yeah, I forgot those. What's that come to, five in all? He's beginning to look like a poster boy for the death penalty, but I wouldn't count on it. Still, five life sentences should keep him on ice for a while. Now if only we had some idea who he is and where to find him."

"You'll find him," I said. "He's good, but he's too cute to stay hidden."

"You know," he said, "I got the same feeling myself. There's one more thing he did, besides the vodka bottle."

"What's that?"

"Well, you gave her your card, didn't you? Your business card?"

"Yes."

"And she must have had it out to dial your number. So where is it?"

"Gone, I gather."

"And it didn't walk off by itself. One more thing to confirm what we already know, which is that she didn't just slip beneath the water's surface and drown of her own accord. Of course there's something else it tells us."

"What's that?"

"Well, he picked up the card. He knows who you are."

Kristin hadn't looked at a paper or listened to the news, so I got to tell her that her cousin was dead. It might have been gentler in person, but I was more interested in saving the time it would take to get from my place to hers. So I didn't see her face when I gave her the news.

"He tried to make it look like accidental death," I said, "but he didn't do a very good job of it, and there's a damn good cop running the investigation. His name's Ira Wentworth, and he'll be in touch with you."

"He'll want to talk to me?"

"Definitely."

"But I don't know anything," she said. "What can I tell him that he doesn't already know?"

Probably nothing, I allowed, but he'd want to establish that for himself. I told her he might be getting someone higher up to authorize police protection for her, and that she should accept a police guard if he offered it. "I don't think you're in danger," I said, "but I didn't think your cousin was in danger, either, and it turned out I was wrong. In the meantime, I don't want you to open your door to anyone but me or Detective Ira Wentworth." I described him, and told her to make sure he showed some ID in that name. "And can you screen your calls? I'd advise you to do that, if only to avoid the press. It's a miracle they haven't learned yet that Lia was your cousin, but they'll get the word before long, and they'll start calling and turning up on your doorstep. Don't talk to them and don't answer the door."

"I won't."

"I mean it, Kristin. It's not just that they'll upset you and waste your time. There's also the fact that one of them could be the man who killed your cousin."

"And my parents."

"Yes."

"I won't let anyone in. Oh."

"What?"

"Well, I'm expecting someone this afternoon."

"Who?"

"His name's David Hamm. He's the man who gave me the ride home the night I found… the night it happened."

He'd waited at the curb, making sure she got in all right.

"It couldn't be him," she said, anticipating my thought, "because he was there all evening, at my friend's house. And the police investigated him thoroughly before they found the two dead bodies in Brooklyn."

"Whose idea was it for him to come over this afternoon?"

"Well, he called. I invited him. He called once before, after the funeral, all concerned, and…"

Her voice trailed off. I said, "Call him now and tell him something's come up, you won't be home, you can't have company."

"All right."

"If he calls back, don't take the call, and don't return it."

"But… all right."

"Call him now, and then call me back."

"All right."

He was probably perfectly all right. He couldn't have been in two places at one time, and the police would have checked him inside and out during the early stages of the investigation. I didn't give a damn. I didn't want him getting close to her, him or anybody else.

I was just starting to wonder what was taking so goddam long when the phone rang and she said it was all taken care of, and was there anything else?

"Yes," I said. "As a matter of fact, there is. Do you know anyone named Arden Brill?"

" Arden Brill."

"Yes. Does the name ring a bell?"

"No, should it?"

"Did anyone ever get in touch with you, recently or in the past, with the explanation that he was doing a doctoral dissertation on your mother?"

"On my mother?"

"On her writing."

"Gosh, no," she said. "I can't imagine that anyone would. I mean, she was serious about her work, and I think she was a fine writer, but she wasn't important to the extent that anyone would write a thesis about her."

"But someone could have been interested in her work."

"Well, sure. I mean, she was an interesting writer, so why wouldn't people be interested?"

"Could you see if she had any correspondence from Arden Brill?"

"Is that who- "

"I don't think he exists," I said, "but I think that's one name that he used."

"I could check her files," she said. "She filed all her correspondence in a cabinet in her studio, and there's a pile of miscellaneous papers, and I could go through those. And I could check her computer, too, and see if his name comes up. First name A-R-D-E-N, last name B-R-I-L-L? I'll call and let you know if I find anything."

I'd tried T J a couple of times earlier but he was out. The second time I remembered to try him on his cell phone- it's never the first thing I think of- and it rang unanswered. I took another shot when I got off the phone with Kristin, and this time he picked up right away.
