Safia frowned at the impossibility of what she was hearing. The woman continued explaining about the explosion at the museum, radiation signatures, the search for the primary source of some stable form of antimatter. Despite her wish to deny it all, much of it began to make sense. Certain statements by Painter, some of his gear, the pressure by the U.S. government.

“The meteor fragment that exploded at the museum,” the woman continued. “It was said to guard the true gates of the lost city of Ubar. It is there that you will lead us.”

She shook her head, more in denial. “This is all preposterous.”

The woman stared a moment longer, stood, and walked across the room. She dragged something from under the table and grabbed a device from among the stacked equipment. As she returned, Safia recognized her own suitcase.

The woman flipped the trunk’s clasps and swung open the lid. The iron heart lay nestled within molded black Styrofoam. It glowed ruddy in the bright sunlight. “This is the artifact you discovered. Inside a statue dating back to 200B.C With the name of Ubar written on its surface.”

Safia slowly nodded, surprised at the woman’s intimate knowledge. She seemed to know everything about her.

The woman leaned down and passed the handheld device over the artifact. The device crackled and popped, sounding not unlike a Geiger counter. “It gives off an extremely low-level radiation signature. Barely detectable. But it’s the same as the exploded meteor. Did Painter ever tell you that?”

Safia remembered Painter testing the artifact with a similar device. Could it be true? Again despair settled to the pit of her stomach, a cold stone.

“We need you to continue your work for us,” the woman said, resealing the trunk. “To guide us to the lost gates of Ubar.”

Safia stared at the closed trunk. All the bloodshed, all the deaths…all tied to her discovery. Again. “I won’t,” she mumbled.

“You will, or you will die.”

Safia shook her head and shrugged. She didn’t care. All that she loved had been taken from her. By this woman. She would never help.

“We will proceed with or without you. There are other experts in your field. And I can make your last hours very unpleasant if you refuse.”

This actually drew a weak laugh from her. Unpleasant? After all she had been through…Safia lifted her head and fully met the woman’s eyes for the first time, a place she had feared staring into until now. They weren’t cold like those of the man who had led her here. They sparked with a deep-seated anger…but also confusion. A frown thinned the woman’s lips.

“Do what you have to,” Safia said, realizing the power in her own despair. This woman could not touch her, harm her. They had taken too much last night. Left nothing that could threaten her. Both of them knew this truth at the same moment.

A flash of worry showed in the pinch of the other’s eyebrows.

She needs me, Safia knew with certainty. The woman had lied about having access to some other expert. She can’t get someone else. Steel flowed through Safia, firming her resolve, firing away the last of her drug-induced lassitude.

Once before, a woman had walked out of nowhere and into her life, a bomb strapped to her chest, passionate with religious fervor, ending lives without mercy. All aimed at Safia.

That woman had died in the explosion back in Tel Aviv. Afterward, Safia had never been able to confront her, to hold her responsible. Instead, she took the guilt upon herself. But it was even more than that. Safia had never been able to exact revenge for the deaths laid at her feet, to purge her guilt.

That was no longer true.

She faced her captor, never breaking eye contact.

She remembered wishing she could’ve stopped that woman in Tel Aviv, met her earlier, somehow prevented the explosion, the deaths. Could it be true about a source of antimatter? She pictured the explosion at the British Museum, the aftermath. What would someone like this woman do with such power? How many more would die?

Safia could not let that happen. “What is your name?”

The question startled her captor. The reaction caused a flash of pleasure to erupt in Safia, as bright as the sun, painful but satisfying.

“You said you’d tell me the truth.”

The woman frowned, but answered slowly. “Cassandra Sanchez.”

“What will you have me do, Cassandra ?” Safia enjoyed the look of irritation in the other at the informal use of her name. “If I cooperate.”

The woman stood, anger flashing. “In an hour, we will leave for the tomb of Imran. Where the heart’s statue was found. Where you were planning to head with the others. That’s where we’ll start.”

Safia stood. “One last question.”

The woman stared at her quizzically.

“Who do you work for? Tell me that and I’ll cooperate.”

Before answering, the woman crossed to the door, opened it, and waved for her man Kane to collect the prisoner. She spoke from the doorway.

“I work for the U.S. government.”

1:01 P.M.

CASSANDRA WAITEDuntil the museum curator had left and the door had been closed. She kicked a palm-frond-woven wastepaper basket across the room, scattering its contents across the plank floor. A Pepsi can rattled and rolled to a stop by the sofa. Fucking bitch…

She had to restrain herself from further outbursts, bottling back her anger. The woman had seemed broken. Cassandra had never imagined her to be so cunning there at the end. She had seen the shift in the other’s eyes, a glacial slide of power from her over to her prisoner. She had been unable to stop it. How had that happened?

She clenched her hands into fists, then forced her fingers to relax and shook her arms. “Bitch…” she mumbled to the room. But at least the prisoner was going to cooperate. It was a victory with which she would have to be satisfied. The Minister would be pleased.

Still, bile churned in her stomach, keeping her mood sour. The curator had more strength in her than Cassandra had imagined. She began to understand Painter’s interest in the woman.

Painter…

Cassandra heaved out a perturbed sigh. His body had never been found. It left her feeling unmoored. If only-

A knock at the door interrupted her thoughts. John Kane pushed inside before she could even turn. Irritation flashed at his blatant invasion of her privacy, his lack of respect.

“Lunch was brought up to the prisoner,” he said. “She’ll be ready at fourteen hundred.”

Cassandra crossed to the table of electronic gear. “How did the subdermal function?”

“Registering perfectly. A good, strong tracking signal.”

Last night, after the prisoner had been drugged, they had implanted a subdermal microtransceiver between her shoulder blades. The same device Cassandra was supposed to have implanted on Zhang back in the States. Cassandra found it especially gratifying to use Painter’s own design in this matter. The microtransceiver would act as an electronic leash on the prisoner when they were on the streets. They would be able to track the curator for a ten-mile radius. Any attempt at escape would be quashed.

“Very good,” she said. “See that your men are all ready.”

“They are.” Kane bristled at her command, but his neck was also on the line if this mission failed.

“Any word from local authorities about the ship’s explosion last night?”

“CNN is blaming it on unknown terrorists.” He snorted at this last.

“What about survivors? Bodies?”

“Definitely no survivors. Salvage is just beginning to determine cause and body count.”

She nodded. “Okay, get your men ready. You’re dismissed.”

Rolling his eyes a bit, he swung away and left the room, pushing the door behind him, but he didn’t close it completely. She had to cross over and shove it the rest of the way. The latch clicked.
