"Why don't you lie down," he said. "There's nothing like a good night's sleep to settle an upset stomach." He turned off the lamp. By the glow of her watch, she saw it was just after seven-thirty. It would be a long wait.

They scarcely slept that night.

In the darkness of their room, they waited for the hours to pass. Outside, the noises of the street, the voices, the tinkle of pedicab bells faded to silence. They didn't undress; they lay tensed in their beds, not daring to exchange a word.

It must have been after midnight when Willy at last slipped into a dreamless sleep. It seemed only moments had passed when she felt herself being nudged awake. Guy's lips brushed her forehead, then she heard him whisper, "Time to move."

She sat up, instantly alert, her heart off and racing. Carrying her shoes, she tiptoed after him to the door.

The hall was deserted. The scuffed wood floor gleamed dully beneath a bare light bulb. They slipped out into the corridor and headed for the stairs.

From the second-floor railing, they peered down into the lobby. The hotel desk was unattended. The sound of snoring echoed like a lion's roar up the stairwell. As they moved down the steps, the hotel lounge came into view, and they spotted the lobby attendant sprawled out on a couch, mouth gaping in blissful repose.

Guy flashed Willy a grin and a thumbs-up sign. Then he led the way down the steps and through a service door. Crates lined a dark and dingy hallway; at the far end was another door. They slipped out the exit.

Outside, the darkness was so thick, Willy found herself groping for some tangible clue to her surroundings. Then Guy took her hand and his touch was steadying; it was a hand she'd learned she could trust. Together they crept through the shadows, into the narrow alley behind the hotel. There they waited.

It was 2:01.

At 2:07, they sensed, more than heard, a stirring in the darkness. It was as if a breath of wind had congealed into something alive, solid. They didn't see the woman until she was right beside them.

"Come with me," she said. Willy recognized the voice: it was Nora Walker's.

They followed her up a series of streets and alleys, weaving farther and farther into the maze that was Hanoi. Nora said nothing. Every so often they caught a glimpse of her in the glow of a street lamp, her hair concealed beneath a conical hat, her dark blouse anonymously shabby.

At last, in an alley puddled with stagnant water, they came to a halt. Through the darkness, Willy could just make out three bicycles propped against a wall. A bundle was thrust into her hands. It contained a set of pajamalike pants and blouse, a conical hat smelling of fresh straw. Guy, too, was handed a change of clothes.

In silence they dressed.

On bicycles they followed Nora through miles of back streets. In that landscape of shadows, everything took on a life of its own. Tree branches reached out to snag them. The road twisted like a serpent. Willy lost all sense of direction; as far as she knew, they could be turning in circles. She pedaled automatically, following the faint outline of Nora's hat floating ahead in the darkness.

The paved streets gave way to dirt roads, the buildings to huts and vegetable plots. At last, at the outskirts of town, they dismounted. An old truck sat at the side of the road. Through the driver's window, a cigarette could be seen glowing in the darkness. The door squealed open, and a Vietnamese man hopped out of the cab. He and Nora whispered together for a moment. Then the man tossed aside the cigarette and gestured to the back of the truck.

"Get in," said Nora. "He'll take you from here."

'' Where are we going?'' asked Willy.

Nora flipped aside the truck's tarp and motioned for them to climb in. "No time for questions. Hurry."

"Aren't you coming with us?"

"I can't. They'll notice I'm gone."

"Who 'll notice?"

Nora's voice, already urgent, took on a note of panic. "Please. Get in now."

Guy and Willy scrambled onto the rear bumper and dropped down lightly among a pile of rice sacks.

"Be patient," said Nora. "It's a long ride. There's food and water inside-enough to hold you."

"Who's the driver?" asked Guy.

"No names. It's safer."

"But can we trust him?"

Nora paused. "Can we trust anyone?" she said. Then she yanked on the tarp. The canvas fell, closing them off from the night.

It was a long bicycle ride back to her apartment. Nora pedaled swiftly, her body slicing through the night, her hat shuddering in the wind. She knew the way well; even in the darkness she could sense where the hazards, the unexpected potholes, lay.

Tonight she could also sense something else. A presence, something evil, floating in the night. The feeling was so unshakable she felt compelled to stop and look back at the road. For a full minute she held her breath and waited. Nothing moved, only the shadows of clouds hurtling before the moon. It's my imagination, she thought. No one was following her. No one could have followed her. She'd been too cautious, taking the Americans up and down so many turns that no one could possibly have kept up unnoticed.

Breathing easier, she pedaled all the way home.

She parked her bicycle in the community shed and climbed the rickety steps to her apartment. The door was unlocked. The significance of that fact didn't strike her until she'd already taken one step over the threshold. By then it was too late.

The door closed behind her. She spun around just as a light sprang on, shining full in her face. Blinded, she took a panicked step backward. "Who-what-"

From behind, hands wrenched her into a brutal embrace. A knife blade slid lightly across her neck.

"Not a word," whispered a voice in her ear.

The person holding the light came forward. He was a large man, so large, his shadow blotted out the wall. "We've been waiting for you, Miss Walker," he said. "Where did you take them?"

She swallowed. "Who?"

"You went to the hotel to meet them. Where did you go from there?"

"I didn't-" She gasped as the blade suddenly stung her flesh; she felt a drop of blood trickle warmly down her neck.

"Easy, Mr. Siang," said the man. "We have all night."

Nora began to cry. "Please. Please, I don't know anything…"

"But, of course, you do. And you'll tell us, won't you?" The man pulled up a chair and sat down. She could see his teeth gleaming like ivory in the shadows. "It's only a question of when."

From beneath the flapping canvas, Willy caught glimpses of dawn: light filtering through the trees, dust swirling in the road, the green brilliance of rice paddies. They'd been traveling for hours now, and the sacks of rice were beginning to feel like bags of concrete against their backs. At least they'd been provided with food and drink. In an open crate they'd found a bottle of water, a loaf of French bread and four hard-boiled eggs. It seemed sufficient-at first. But as the day wore on and the heat grew suffocating, that single bottle of water became more and more precious. They rationed it, one sip every half hour; it was barely enough to keep their throats moist.

At noon the truck began to climb.

"Where are we going?" she asked.

"Heading west, I think. Into the mountains. Maybe the road to Dien Bien Phu."

"Towards Laos?"

"Where your father's plane went down." In the shadows of the truck, Guy's face, dirty and unshaven, was a tired mask of resolution. She wondered if she looked as grim.

He shrugged off his sweat-soaked shirt and threw it aside, oblivious to the mosquitoes buzzing around them. The scar on his bare abdomen seemed to ripple in the gloom. In silent fascination, Willy started to reach out to him, then thought better of it.
