Again I heard men behind me. Shuffling feet, hissing silk, irregular respiration. Were they trying to gauge my reaction to this Occidental woman in the most vulnerable state a woman can be in? Although if she was dead, she was technically invulnerable. Yet this gawking at her corpse by strangers seemed somehow a final insult, an ultimate humiliation. We cover corpses for the same reason we go behind walls to carry out our bodily functions; some human states cry out for privacy, and being dead is one of them. Respect above all is called for, not for the body, but for the person who recently departed it.

Someone paid two million dollars for a painting like this one. Maybe even for this one. A man paid that, of course. A woman would have bought this painting only to destroy it. Ninety-nine out of a hundred women, anyway. I closed my eyes and said a prayer for the woman in the picture, on the chance that she was real. Then I moved on.

The next painting hung beyond a small bench set against the wall. It was smaller than the others, perhaps two feet by three, with the long axis vertical. Two men stood before it, but they weren’t looking at the canvas. They gaped like clubbed mackerel as I approached, and I imagined that if I pulled down their starched white collars, I would find gills. No taller than I, they backed quickly out of my way and cleared the space before the painting. As I turned toward it, a premonitory wave of heat flashed across my neck and shoulders, and I felt the dry itch of the past rubbing against the present.

This woman was naked as well. She sat in a window seat, her head and one shoulder leaned against the casement, her skin lighted by the violet glow of dawn or dusk. Her eyes were half open, but they looked more like the glass eyes of a doll than those of a living woman. Her body was thin and muscular, her hands lay in her lap, and her Victorian-style hair fell upon her shoulders like a dark veil. Though she had been sitting face-on to me from the moment I looked at the canvas, I suddenly had the terrifying sensation that she had turned to me and spoken aloud. The taste of old metal filled my mouth, and my heart ballooned in my chest. This was not a painting but a mirror. The face looking back at me from the wall was my own. The body, too, mine: my feet, hips, breasts, my shoulders and neck. But the eyes were what held me, the dead eyes – held me and then dropped me through the floor into a nightmare I had traveled ten thousand miles to escape. A harsh burst of Chinese echoed through the room, but it was gibberish to me. My throat spasmed shut, and I could not scream or even breathe.

Thirteen months ago, on a hot summer morning, my twin sister Jane stepped out of her town house on St. Charles Avenue in New Orleans to run her daily three-mile round of the Garden District. Her two young children waited inside with the maid, first contentedly, then anxiously as their mother’s usual absence stretched beyond any they remembered. Jane’s husband Marc was working in blissful ignorance at his downtown law firm. After ninety minutes, the maid called him.

Knowing you could walk one block out of the Garden District and be in a free-fire zone, Marc Lacour immediately left work and drove the streets of their neighborhood in search of his wife. He cut the Garden District into one-block grids from Jackson Avenue to Louisiana and methodically drove them a dozen times. Then he walked them. He left the Garden District and questioned every porch-sitter, shade-tree mechanic, can-kicker, crack dealer, and homeless person he could find on the adjoining streets. No one had heard or seen anything of Jane. A prominent attorney, Marc immediately called the police and used his influence to mount a massive search. The police found nothing.

I was in Sarajevo when Jane disappeared, shooting a series on the aftermath of the war. It took me seventy-two hours to get to New Orleans. By that time, the FBI had entered the picture and subsumed my sister’s disappearance into a much larger case, designated NOKIDS in FBI-speak, for New Orleans Kidnappings. It turned out that Jane was fifth in a rapidly growing group of missing women, all from the New Orleans area. Not one corpse had been found, so all the women were classified as victims of what the FBI called a “serial kidnapper.” This was the worst sort of euphemism. Not one relative had received a ransom note, and in the eyes of every cop I spoke to, I saw the grim unspoken truth: every one of those women was presumed dead. With no crime-scene evidence, witnesses, or corpses to work with, even the Bureau’s vaunted Investigative Support Unit was stumped by the cold trail. Though women continued to disappear and still do, neither the Bureau nor the New Orleans police have come close to discovering the fate of my sister or any of the others.

I should clarify something. Not once since my father vanished in Cambodia have I sensed that he was truly dead, gone from this world. Not even with the last frame of film he shot showing an executioner’s pistol pointed at his face. Miracles happen, especially in war. For this reason I’ve spent thousands of dollars over the past twenty years trying to find him, piggybacking my money with that of the relatives of Vietnam-era MIAs, giving what would have been my retirement money to scam artists and outright thieves, all in the slender hope that one lead among the hundreds will turn out to be legitimate. On some level, my decision to take the advance for my book was probably a way to be paid to hunt for my father in person, to tramp across Asia with an eye to my camera and an ear to the ground.

With Jane it’s different. By the time my agency tracked me down on a CNN satellite phone in Sarajevo, something had already changed irrevocably within me. As I crossed a street once infested with snipers, a nimbus of dread welled up in my chest – not the familiar dread of a bullet with my name on it, but something much deeper. Whatever energy animates my soul simply stopped flowing as I ran, and the street vanished. I kept running blindly into the dark tunnel before me, as though it were nine years before, during the worst of it, when the snipers shot anything that moved. A CNN cameraman yanked me behind a wall, thinking I’d seen the impact of a silenced bullet on the concrete. I hadn’t, but a moment later, when the street returned, I felt as though a bullet had punched through me, taking with it something no doctor could ever put back or put right.

Quantum physics describes “twinned particles,” photons of energy that, even though separated by miles, behave identically when confronted with a choice of paths. It is now thought that some unseen connection binds them, defying known physical laws, acting instantaneously without reference to the speed of light or any other limit. Jane and I were joined in this way. And from the moment that dark current of dread pulsed through my heart, I felt that my twin was dead. Twelve hours later, I got the call.

Thirteen months after that – two hours ago – I walked into the museum in Hong Kong and saw her painted image, naked in death. I’m not sure what happened immediately after. The earth did not stop turning. The cesium atoms in the atomic clock at Boulder did not stop vibrating. But time in the subjective sense – the time that is me – simply ceased. I became a hole in the world.

The next thing I remember is sitting in this first-class seat on a Cathay Pacific 747 bound for New York, a Pacific Rim sunset flaring in my window as the four great engines thrum, their vibration causing a steady ripple in the scotch on the tray before me. That was two whiskeys ago, and I still have another nineteen hours in the air. My eyes are dry and grainy, stinging. I am cried out. My mind gropes backward toward the museum, but there is something in the way. A shadow. I know better than to try to force the memory. I was shot once in Africa, and from the moment the bullet ripped through my shoulder till the moment I came to my senses in the Colonial Hotel and found myself being patched up by an Australian reporter whose father was a doctor, everything was blank. The missing events – a hectic jeep ride down an embattled road, the bribing of a checkpoint guard (in which I participated) – only returned to me later. They had not disappeared, but merely fallen out of sequence.
