But no, it's too late now. The Hollanders have arrived, they're climbing the half-flight of marble steps to their front door. Do they sense an alien presence within? It's possible that they do. Susan Hollander is a creative person, artistic, intuitive. Her husband is more traditionally practical, trained to deal in facts and logic, but his professional experience has taught him to trust his intuition.

She has a feeling, and she takes his arm. He turns, looks at her, can almost read the thought written on her face. But all of us get feelings all the time, premonitions, vaguely disquieting intimations. Most of them turn out to be nothing, and we learn to ignore them, to override our personal early warning systems. At Chernobyl, you may recall, the gauges indicated a problem; the men who read the gauges decided they were faulty, and ignored them.

He has his key out, and slips it into the lock. Inside, the two men hear the key in the lock. The seated man gets to his feet, the pacer moves toward the door. Byrne Hollander turns the key, pushes the door open, lets his wife enter first, follows her inside.

Then they catch sight of the two men, but by now it's too late.

I could tell you what they did, what they said. How the Hollanders begged and tried to bargain, and how the two men did what they'd already decided to do. How they shot Byrne Hollander three times with a silenced.22 automatic, twice in the heart and once in the temple. How one of them, the pacer, raped Susan Hollander fore and aft, ejaculating into her anus, and then thrust the fireplace poker into her vagina, before the other man, the one who had been sitting patiently earlier, out of mercy or the urge to get out of there, grabbed her by her long hair, yanked her head back forcefully enough to separate some hairs from her scalp, and cut her throat with a knife he'd found in the kitchen. It was of carbon steel, with a serrated edge, and the manufacturer swore it would slice through bone.

I would be imagining all of this, just as I imagined them holding hands as they crossed the street, even as I imagined the two men waiting for them, one sitting in the tobacco-brown chair, the other pacing before the fireplace. I have let my imagination work with the facts, never contradicting them but filling in where they leave off. I don't know, for example, that some inner prompting warned either or both of the Hollanders that danger waited within their house. I don't know that the rapist and the knife-wielder were different men. Maybe the same man raped her as killed her. Maybe he killed her while he was inside of her, maybe that increased his pleasure. Or maybe he tried it out, thinking it might heighten his climax, and maybe it did, or maybe it didn't.

Susan Hollander, sitting at her desk on the top floor of her brownstone, used her imagination to write her stories. I have read some of them, and they are dense, tightly crafted constructions, some set in New York, some in the American West, at least one set in an unnamed European country. Her characters are at once introspective and, often, thoughtless and impulsive. They are, to my mind, not much fun to be around, but they are convincingly real, and they are clearly creatures of her imagination. She imagined them, and brought them to life upon the page.

One expects writers to use their imaginations, but that portion of the mind, of the self, is as much a part of the equipment of a policeman. A cop would be better off without a gun or a notebook than without an imagination. For all that detectives, private and public, deal in and count on facts, it is our capacity to reflect, to imagine, that points us to solutions. When two cops discuss a case they're working on, they talk less about what they know for a fact than what they imagine. They construct scenarios of what might have happened, and then look for facts that will support or knock down their constructions.

And so I have imagined the final moments of Byrne and Susan Hollander. Of course I have gone much farther in my imagination than I have felt it necessary to recount here. The facts themselves go farther than I've gone here- the blood spatters, the semen traces, the physical evidence painstakingly gathered and recorded and assessed by the forensic technicians. Even so, there are questions the evidence doesn't answer unequivocally. For example, which of the Hollanders died first? I've suggested that they shot Byrne Hollander before they raped his wife, but it could have been the other way around; the physical evidence allows for either scenario. Perhaps he had to watch her violation and hear her screams until the first bullet mercifully blinded and deafened him. Perhaps she saw her husband killed before she was seized and stripped and taken. I can imagine it either way, and have in fact imagined it every possible way.

Here is how I prefer to imagine it: Almost as soon as they are inside the house and the door is kicked shut, one of the men shoots Byrne Hollander three times, and he is dead before the third bullet enters his body, dead before he hits the floor. The shock alone is enough to induce an out-of-body experience in his wife, and Susan Hollander, disembodied, hovers somewhere near the ceiling and watches, emotionally and physically disconnected, while her body is abused on the floor below her. Then, when they cut her throat, that body dies, and the part of her that has been watching is drawn down that long tunnel that seems to be a part of all near-death experiences. There's a white light, and she's drawn into the light, and there she finds the people who loved her and are waiting for her. Her grandparents, of course, and her father, who died when she was a child. Her mother, who died just two years ago, and her son, of course, Sean. There's never been a day that she hasn't thought of Sean, and he's there now, waiting for her.

And her husband's there, too. They were only apart for a few minutes, really, and now they'll be together forever.

Well, that's how I prefer to imagine it. And it's my imagination. I guess I can do as I please with it.

TWO

Their daughter Kristin found the bodies. She'd spent the evening with friends in Chelsea and was going to stay over at a girlfriend's apartment in London Terrace, but that would have meant wearing the same clothes to work in the morning or else running home first to change. A man she'd just met offered her a ride home, and she took it. It was a few minutes after one when he pulled up and double-parked in front of the house on West Seventy-fourth.

He was going to walk her to her door, but she stopped him. Still, he waited while she crossed the sidewalk and mounted the steps, waited while she used her key, waited until she was inside. Did he sense something? Probably not. I suspect it was habit, the way he was brought up: when you see a woman home, you wait until she's safely inside before you take your leave.

So he was still there, just about to pull away, when she reappeared in the doorway, her face a mask of horror. He killed the ignition and got out to see what was the matter.

The story broke much too late for the morning papers, but it was the lead item on the local news, so Elaine and I learned about it at breakfast. The gal on New York One reported that the victims had attended a concert at Lincoln Center that evening, so we knew we'd been there listening to the same music with them; what we didn't know then was that they'd been at the patrons' reception and dinner as well. It was unsettling to think we'd been in the same concert hall with them, along with several thousand other people; it would be more unsettling later to realize that we'd all been part of a considerably more intimate gathering.

The double murder was more than front-page news. It was, in journalistic terms, a wonderful story. The victims, a prominent attorney and a published writer, were decent, cultured people, murdered brutally in their own home. She'd been raped, always a bonus for the tabloid reader, and subjected to a second violation with the fireplace poker. In a less outspoken time than ours, that last detail would have been veiled. The police generally hold back something like that, to make it easier to screen false confessions, but this time the press got hold of it. The Times left it unreported, perhaps out of decency, and the TV news hinted at a further violation without getting specific, but the News and the Post showed no such restraint.

A police canvass of the area turned up a neighbor who had spotted two men leaving a house, probably the Hollander house, sometime after midnight and before one. She noticed their departure because each had a laundry bag slung over his shoulder. She didn't regard the sight as suspicious, never thinking they might be burglars, assuming instead that they were roommates, headed for the twenty-four-hour laundromat around the corner on Amsterdam. She remembered thinking that it was a shame young people had to work such long hours these days, and the only time they had to do their laundry was in the middle of the night.

The description she furnished was vague, and a session with a police artist led nowhere, as she had never gotten a clear look at their faces. They were, as she recalled, neither tall nor short, neither fat nor thin. She thought, although she couldn't swear to it, mind you, that one of them might have had a beard.

Forensics thought she might be right. They'd recovered a couple of hairs that had almost certainly come from a man's beard, and you didn't need a DNA check to know they weren't Byrne Hollander's, as he was clean-shaven.

According to the woman, it was possible that one of them limped. She remembered there was something awkward about his walk, attributing it at the time to the weight of the sack of laundry he was carrying. And maybe that's all it was, but maybe he'd been limping. She couldn't say for sure.

When you luck into a story that sells papers, you keep it on the front page whether or not there are any new developments. The Post showed the most imagination, actually running a sketch of the suspect with the headline HAVE YOU SEEN HIM LIMPING? It showed a man with a Mephistophelian beard and generally demonic facial features, a sack slung over his shoulder, furtively slouching. Toward Amsterdam Avenue, I suppose, if not Bethlehem. The implication, of course, was that this was a police sketch, but it was no such thing. Some staff artist at the paper had cobbled it up to order and there it was on the front page, with the Post's readers urged to come up with a name to go with the imaginary face.

And, of course, dozens of them did, flooding the police tip line, the number of which the paper had been considerate enough to furnish. When someone phones in a tip in a high-profile case, you can't dismiss it out of hand, even when it's the result of some journalist's fantasy. There's always the possibility that the tip's legit, that the caller's using the sketch as an excuse to point the police toward someone of whom he has reason to be suspicious. Every call gets checked out, not because those checking expect results, but because they know how they'll look if the tip they overlook turns out to be on the money. The first thing you learn in the NYPD, on the job if not in classes at the academy, is to cover your ass. And the job keeps on teaching it to you, over and over.

One caller said the cops ought to take a look at a guy named Carl Ivanko. It wasn't that the sketch looked like him, exactly, because Carl's face was sort of lopsided, as well as longer and narrower than the face in the sketch. And the caller didn't know if Carl had a beard. Facial hair was sort of an on-and-off thing with him, and it had been a while since the caller ran into Carl, and if he never saw him again, well, that would be fine.

So it was more the description than the sketch, really, that had brought Carl to mind, although there was something about the sketch that had triggered his action, even though it didn't bear much resemblance to Carl. The thing was, Carl had something wrong with his hip, and it gave him an awkward walk some of the time. It wasn't a limp, not exactly, but what it came down to was he walked funny.
