I remembered after the presentation Rader had poured me a Jack Daniel's, neat and straight up in a paper cup, and we had reminisced about the old days when there were few forensic pathologists and I was the only woman. Rader was getting close to sixty and was much acclaimed by his peers. But he would not have made a good chief. He did not relish warfare with paperwork and politicians.

We looked like we were suiting up for outer space as we put on air packs, face shields and hoods. AIDS was a worry if one got a needle stick or cut while working on an infected body, but a bigger threat were infections borne on air, such as tuberculosis, hepatitis and meningitis. These days we double-gloved, breathed purified air and covered ourselves with greens and gowns that could be thrown away. Some medical examiners like Rader wore stainless steel mesh gloves reminiscent of chain mail.

I was pulling the hood over my head when O'Donnell, the detective I had met last night, walked in with Marino, who looked irritable and hungover. They put on surgical masks and gloves, no one meeting anybody's eyes or speaking. Our nameless case was in steel drawer 121, and as we filed out of the locker room, mortuary assistants hoisted the body out and set it on top of a gurney. The dead woman was nude and pitiful on her cold, steel tray.

Areas of flesh excised from her shoulder and inner thighs were ghastly patches of darkened blood. Her skin was bright pink from cold livor mortis, typical in frozen bodies or people who have died of exposure. The gunshot wound to her right temple was large caliber, and I could see at a glance the distinct muzzle mark stamped into her skin when Gault had pressed the pistol's barrel against her head and pulled the trigger.

Men in scrubs and masks rolled her into the X-ray room, where each of us was given a pair of orange-tinted plastic glasses to add to our armor. Rader set up a light energy source called a Luma-Lite, which was a simple black box with an enhanced blue fiber-optic cable. It was another set of eyes that could see what ours could not, a soft white light that turned fingerprints fluorescent and caused hairs, fibers and narcotic and semen stains to glare like fire.

'Someone hit the lights,' Rader said.

In the dark, he began going over the body with the Luma-Lite, and multiple fibers lit up like fine-gauge hot wire. With forceps, Rader collected evidence from pubic hair, feet, hands and the stubble on her scalp. Small areas of yellow got bright like the sun as he passed the light over the finger pads of her right hand.

'She's got some chemical here,' Rader said.

'Sometimes semen lights up like that.'

'I don't think that's it.'

'It could be street drugs,' I offered my opinion.

'Let's get it on a swab,' said Rader. 'Where's the hydrochloric acid?'

'Coming up.'

The evidence was recovered and Rader moved on. The small white light passed over the geography of the woman's body, into the dark recessed areas where her flesh had been removed, over the flat plain of her belly and gentle slopes of her breasts. Virtually no trace evidence clung to her wounds. This corroborated our theory that Gault had killed and maimed her where she was found, because had she been transported after the assault, debris would have adhered to drying blood. Indeed, her injuries were the cleanest areas of her body.

We worked in the dark for more than an hour, and she was revealed to me inches at a time. Her skin was fair and seemed a stranger to the sun.
