Two uniformed men flanked the front door, which was open wide and barred by a yellow ribbon of tape, warning: CRIME SCENE-DO NOT CROSS.

"Doc."

He could have been my son, this boy in blue who stepped aside at the top of the steps and lifted the tape to let me duck under.

The living room was immaculate, and attractively decorated in warm rose tones. A handsome cherry cabinet in a corner contained a small television and a compact disc player. Nearby a stand held sheet music and a violin. Beneath a curtained window overlooking the front lawn was a sectional sofa, and on the glass coffee table in front of it were half a dozen magazines neatly stacked. Among them were Scientific American and the New England Journal of Medicine. Across a Chinese dragon rug with a rose medallion against a field of cream stood a walnut bookcase. Tomes straight from a medical school's syllabi lined two shelves.

An open doorway led into a corridor running the length of the house. To my right appeared a series of rooms, to the left was the kitchen, where Marino and a young officer were talking to a man I assumed was the husband.

I was vaguely aware of clean countertops, linoleum and appliances in the off-white that manufacturers call "almond," and the pale yellow of the wallpaper and curtains. But my attention was riveted to the table. On top of it lay a red nylon knapsack, the contents of which had been gone through by the police: a stethoscope, a penlight, a Tupperware container once packed with a meal or a snack, and recent editions of the Annals of Surgery, Lancet and the Journal of Trauma. By now I was thoroughly unsettled.

Marino eyed me coolly as I paused by the table, then introduced me to Matt Petersen, the husband. Petersen was slumped in a chair, his face destroyed by shock. He was exquisitely handsome, almost beautiful, his features flawlessly chiseled, his hair jet-black, his skin smooth and hinting of a tan. He was wide shouldered with a lean but elegantly sculpted body casually clad in a white Izod shirt and faded blue jeans. His eyes were cast down, his hands stiffly in his lap.

"These are hers?" I had to know. The medical items might belong to the husband.

Marino's "Yeah" was a confirmation.

Petersen's eyes slowly lifted. Deep blue, bloodshot, they seemed relieved as they fixed on me. The doctor had arrived, a ray of hope where there was none.

He muttered in the truncated sentences of a mind fragmented, stunned, "I talked to her on the phone. Last night. She told me she'd be home around twelve-thirty, home from VMC, the ER. I got here, found the lights out, thought she'd already gone to bed. Then I went in there."

His voice rose, quivering, and he took a deep breath. "I went in there, in the bedroom."

His eyes were desperate and welling, and he was pleading with me. "Please. I don't want people looking at her, seeing her like that. Please. "I gently told him, "She has to be examined, Mr. Petersen."

A fist suddenly banged the top of the table in a startling outburst of rage. "I know!"

His eyes were wild. "But all of them, the police and everybody!"

His voice was shaking. "I know how it is! Reporters and everybody crawling all over the place. I don't want every son of a bitch and his brother staring at her!"

Marino didn't bat an eye. "Hey. I got a wife, too, Matt. I know where you're coming from, all right? You got my word she gets respect. The same respect I'd want if it was me sitting in your chair, okay?"

The sweet balm of lies.

The dead are defenseless, and the violation of this woman, like the others, had only begun. I knew it would not end until Lori Petersen was turned inside out, every inch of her photographed, and all of it on display for experts, the police, attorneys, judges and members of a jury to see. There would be thoughts, remarks about her physical attributes or lack of them. There would be sophomoric jokes and cynical asides as the victim, not the killer, went on trial, every aspect of her person and the way she lived, scrutinized, judged and, in some instances, degraded.

A violent death is a public event, and it was this facet of my profession that so rudely grated against my sensibilities. I did what I could to preserve the dignity of the victims. But there was little I could do after the person became a case number, a piece of evidence passed from hand to hand. Privacy is destroyed as completely as life.

Marino led me out of the kitchen, leaving the officer to continue questioning Petersen.

"Have you taken your pictures yet?" I asked.

"ID's in there now, dusting everything," he said, referring to the Identification section officers processing the scene. "I told 'em to give the body a wide berth."

We paused in the hallway.

On the walls were several nice watercolors and a collection of photographs depicting the husband's and the wife's respective graduating classes, and one artistic color shot of the young couple leaning against weathered piling before a backdrop of the beach, the legs of their trousers rolled up to their calves, the wind ruffling their hair, their faces ruddy from the sun. She was pretty in life, blond, with delicate features and an engaging smile. She went to Brown, then to Harvard for medical school. Her husband's undergraduate years were spent at Harvard. This was where they must have met, and apparently he was younger than she.

She. Lori Petersen. Brown. Harvard. Brilliant. Thirty years old. About to have it all realized, her dream. After eight grueling years, at least, of medical training. A physician. All of it destroyed in a few minutes of a stranger's aberrant pleasure.

Marino touched my elbow.

I turned away from the photographs as he directed my attention to the open doorway just ahead on the left.

"Here's how he got in," he said.

It was a small room with a white tile floor and walls papered in Williamsburg blue. There was a toilet and a lavatory, and a straw clothes hamper. The window above the toilet was open wide, a square of blackness through which cool, moist air seeped and stirred the starchy white curtains. Beyond, in the dark, dense trees, cicadas were tensely sawing.

"The screen's cut." Marino's face was expressionless as he glanced at me. "It's leaning against the back of the house. Right under the window's a picnic table bench. Appears he pulled it up so he could climb in."

I was scanning the floor, the sink, the top of the toilet. I didn't see dirt or smudges or footprints, but it was hard to tell from where I was standing, and I had no intention of running the risk of contaminating anything.

"Was this window locked?" I asked.

"Don't look like it. All the other windows are locked. Already checked. Seems like she would've gone to a lot of trouble to make sure this one was. Of all the windows, it's the most vulnerable, close to the ground, in back where no one can see what's going on. Better than coming in through the bedroom window because if the guy's quiet, she's not going to hear him cutting the screen and climbing in this far down the hall."

"And the doors? Were they locked when the husband got home?"

"He says so."

"Then the killer went out the same way he came in," I decided.

"Looks that way. Tidy squirrel, don't you think?"

He was holding on to the door frame, leaning forward without stepping inside. "Don't see nothing in here, like maybe he wiped up after himself to make sure he didn't leave footprints on the john or floor. It's been raining all day."

His eyes were flat as they fixed on me. "His feet should've been wet, maybe muddy."
