Bennett, staring out the window as they barreled along the Georgetown Pike, frowned. "I don't have to tell you that the soon-to-be First Daughter's abduction has caused an intelligence mobilization of nine-eleven proportions." He turned to Jack. "The head of the special task force in charge of the investigation has requested you, not simply because you're my best agent by far, but I assume because of Emma."

That was logical, Jack thought. Emma and Alli both went to Langley Fields; they were roommates and good friends.

When the limo turned onto Langley Fields Drive from Georgetown Pike, it was met by a fleet of unmarked cars. There was not a police or other official vehicle to be seen. The limo stopped while the driver handed over his creds; then a grim-faced suit with an earful of wireless electronics waved them through the tall black wrought-iron gates onto the school grounds, which were guarded by a twelve-foot-high brick wall topped by wrought-iron spikes. Jack felt sure those metal points were more than decorative.

Langley Fields was the epitome of an exclusive, expensive women's college. The colonial-style white brick buildings were scattered across a magnificently groomed campus whose expansive acreage now revealed volleyball and tennis courts, a softball field, an indoor gym, and swimming facilities. They passed a professional dressage ring on their right, behind which was the long, low clapboard stable, its doors closed against the winter chill. Beside it, neat golden bales of pale hay were piled high.

The limo crunched over blue-gray gravel, moving along a sweeping drive toward the sprawling administration building. Jack pressed the button that rolled down his window and stuck his head out. At regular intervals, unmarked cars had been pulled unceremoniously onto the immaculately tended lawns, green even at this time of year. Beside them, more suits with ear candy consulted with the outdoor staff or were either setting out or returning in search parties of three or four.

Jack counted three sets of K-9 unit dogs straining at the ends of their handlers' leashes as they tried to catch a trace of Alli Carson's scent. High overhead a stationary helicopter whirred, no more than another bird with acute vision. With the president-elect's priority visits, the chopper wouldn't betray any unusual activity to the school's neighbors, Jack surmised.

The suits watched the limo's slow passage, their pale gimlet eyes narrowing as they spotted Jack. Their mouths turned down in disdain or outright hostility. He was an outsider come to take their Golden Fleece, make it his own. As they realized this change in the order of things, they bared their teeth slightly, and, aggrieved, their cheeks puffed up.

The car came to a stop under the porte cochere, held aloft by massive fluted Doric columns. Jack stepped out, but when the chief didn't follow, he turned, bent into the interior.

"This is as far as I go." Bennett's face was impassive, but his fingers were firmly laced together on his lap. "Your ass belongs to someone else now." His lips seemed to twitch in a grimace. "A word to the wise, Jack. This is a different arena. You go off the grid, they'll for damn sure make you wish you were dead."

JACK, ID'D at the front door, was taken in through the vast echoing vestibule, with its domed ceiling, huge ormolu-framed mirror, and ornate spiral staircase to forbidden upper floors. A crystal chandelier hung like a cloud of tears caught in the moment before it's drops fall to earth.

The familiar polished mahogany console with its gold-tipped cabriole legs, delicate as a fawn's, stood to the left, a large bouquet of purple-blue hothouse irises rising from within its glass bed. To the right, through mahogany pocket doors, was the sumptuous drawing room used for teas given by the headmistress or for holiday parties. Jack stood for a moment, transfixed, as he stared in at the room's yellow walls, yellow flowered sofas and chairs, white trim. He saw himself with Sharon and Emma, having tea with the headmistress. He remembered their hostess had worn an unfashionable dress. In sharp contrast to Emma's shockingly short pleated skirt and formfitting V-neck sweater, the dress was ankle-length, covered with tiny Victorian flowers amid twining vines. In fact, it was Emma's alterations of the college's dress code-what the headmistress labeled subversive-that was the subject of the conference over tea, scones, and clotted cream. Jack had been proud of how his daughter stood up for her rights, though both the headmistress and Sharon had been scandalized. Inevitably, his gaze was magnetized to one of the sofas where Emma had sat, ankles primly crossed, hands in her lap, staring at a spot somewhere over the headmistress's left shoulder, her expression for once solemn as an adult's. She spoke respectfully when asked for an explanation, throughout seemed contrite. But this, Jack suspected, was merely a ploy to end the inquisition. Tomorrow, he was willing to bet, she would show up in class as outrageously dressed as before. The memory made him want to laugh and cry at the same time. From the moment the limo had entered the gates of Langley Fields, he was plunged into the past, and now he knew there was no escape.

He was about to turn away when his eye was caught by a slight rippling of the window drapes. His escort cleared his throat and Jack put up a hand. Quickly crossing the room, he pulled aside the drape. The window was firmly shut, but there came to him the hint of a smell: mascara, makeup, something Emma had used on her face. Behind him, he heard a whisper. Burnished light seemed to fall on the narrow space between the window and the drape. A shadow moved, a whisper like wind through a field of grass. Was it his daughter's voice?

A tiny thrill shot up his spine. "Emma?" he said under his breath. "Are you here? Where are you?"

Nothing. The smell had vanished. He stood for a moment, lost in time, feeling like an idiot. Why can't you face it? he told himself. She's gone. But he knew why. During the six months while Sharon was popping pills behind his back, while she and Jeff were finding shadowed corners to couple in, while his marriage was falling apart, he'd spent every minute of his spare time trying to piece together the hours before Emma's death. The truth was, he hardly slept, using the nighttime hours to prowl, run down leads, talk to snitches. Emma's cell phone, crushed in the accident, was no help, but he got a friend at the phone company to pull her records. He worked the list of numbers, building charts of her friends and acquaintances, but always the nodes and connectors circled back on themselves, like a snake eating its tail. He laboriously read the transcripts of her text messages for the previous two weeks, the longest the phone company kept such things. He scoured the hard drive of her laptop, looking for suspicious e-mails, links to Internet chat rooms, unfamiliar, possibly dangerous Web sites. It was like the dark side of the moon in there, the hard disk was clean of such ubiquitous detritus. If this had been a spy novel, he'd suspect it had been purged, but Emma was no spy and this wasn't a novel. He spent hours with Alli Carson, braced the faculty and staff at the school. He interviewed every neighbor of the school's in an ever-widening circle until even he understood he'd exhausted all possibilities. He'd run down all Emma's girlfriends until the father of one had taken out a restraining order on him. He'd followed every possible lead, even ones that appeared improbable. For his tireless and often frenzied efforts, he'd come up with nothing. After six months, he was no closer to finding out what had frightened his daughter so thoroughly. She'd always been something of a fearless creature. Not reckless, so far as he knew-though he'd finally had to admit to himself that he'd known Emma not at all. The bitter truth, as Sharon had said, was that their daughter had a secret life from which, even in death, they were excluded.
