He had to stop them.

Bending down, he retrieved his knife from the floor. “Stay here,” he said softly in Mandarin. He rushed to the main room and used the dagger to pry off the ventilation grille. It snapped open with a pop of screws. He reached within and grabbed the black device hidden inside. The EM grenade was roughly the size and shape of a football.

Palming the device, he fled to the suite’s door and out into the hall. Still without his shoes, he sprinted down the carpeted hall. He analyzed a quick schematic in his head, coordinating where the north exit was in relation to his location on this floor. He did a best-guess estimate.

Eight doors down he stopped and pulled out his security key again. He swiped it through the electronic lock and shoved the door open as soon as it flashed green. “Security!” he hollered, and raced into the room.

An older woman, the same one he had spotted earlier, sat in a chair reading USA Today. She tossed the paper in the air and clutched her robe to her throat. “Was ist los?” she asked in German.

He hurried past her to the window, reassuring her that nothing was wrong. “Nichts, sich ungefдhr zu sorgen, fraulein,” he answered.

He slid the window open. Again it was only enough to stick his head through. He glanced down.

The Lincoln Town Car idled below. The rear door to the sedan slammed shut. Shots rang out. Slugs pelted the side of the car as its tires squealed and smoked, but the car had been bulletproofed, an American-built tank.

Painter leaned back and shoved the football-shaped device out the window. He depressed the activation button and threw the grenade straight down with all the force in his shoulder, hoping for a Hail Mary pass.

He pulled his arm back inside. The wheels of the Town Car stopped squealing as it gained traction. He sent a prayer to the spirits of his ancestors. The EM pulse range was only twenty yards. He held his breath. What was that old saying? Close only counts in horseshoes and hand grenades.

As he held his breath, the muffled whump of the grenade finally sounded. Had he been close enough?

He leaned his head back outside.

The Town Car reached the near corner of the tower, but rather than making the turn, it swerved uncontrollably and struck a row of parked cars head-on. The front of the Lincoln climbed up the hood of a Volkswagen Passat and came to a crooked rest.

He sighed.

That was the good thing about EM pulses. They didn’t discriminate about what computer systems they fried. Even those that operated a Lincoln Town Car.

Below, uniformed security personnel poured from the exit and quickly surrounded the disabled car.

“Was ist los?” the old German woman repeated behind him.

He turned and hurried across the room. “Etwas Abfall gerade entleeren.” Just dumping some garbage. He crossed quickly down the hall to the elevator lobby. Retrieving his shoes from the jammed elevator door, he hit the button for the main floor.

His stunt had stopped Zhang’s escape, but it had also surely wiped out the computer he carried, destroying the research data. But that was not Painter’s main concern.

Cassandra.

He had to get to her.

As soon as the doors opened, he rushed across the gambling floor, where pandemonium reigned. The firefight had not gone unnoticed, though a few people still sat calmly in front of their slot machines, pushing their buttons with dogged determination.

He crossed to the north exit and had to run through a series of blockades, flashing his identification, frustrated at being held back. Finally he spotted John Fenton, head of security, and called out to him. He ushered Painter through the shattered exit. Safety glass crunched underfoot and the telltale taint of gunpowder hung in the air.

“I don’t understand why the car crashed,” Fenton said. “Lucky for us, though.”

“Not just luck,” Painter said, and explained about the EM pulse and its twenty-yard range. “A few guests are going to have a hard time starting their cars this morning. And there’ll probably be a few fried televisions on the first floors.”

Outside, Painter saw that the local security had things in hand. Additionally, a row of charcoal gray police cars, lights flashing, wound through the parking lot, circling down upon the site. The MP Tribal Police.

Painter searched the area. Zhang’s bodyguards were down on their knees, fingers laced behind their heads. Two bodies were sprawled on the ground, security coats draped over their faces. They were both men. Painter crossed to them and peeled one suit back. Another bodyguard, half his face gone. He didn’t have to check the other. He recognized Zhang’s polished leather shoes.

“He shot himself,” a familiar voice said from amid a group of security men and a pair of EMTs. “Rather than be captured.”

Painter turned and saw Cassandra step forward. Her face was pale, her smile shy. She was only in her bra. Her left shoulder was lost in a bandage.

She nodded to a black suitcase a few feet away. Zhang’s computer.

“So we lost the data,” he said. “The EM pulse wiped it.”

“Maybe not,” she said with a grin. “The case is shielded with a copper Faraday cage. It should’ve been insulated from the pulse.”

He sighed with relief. So the data was safe. All was not lost…that is, if they could retrieve the pass code. He stepped toward Cassandra. She grinned at him, eyes still shining. He pulled his Glock and pressed it to her forehead.

“Painter, what are you-” She stepped back.

He followed, never letting his gun drop. “What’s the code?”

Fenton moved to one side. “Commander?”

“Stay out of it.” He cut the security chief off and maintained his attention on Sanchez. “Four bodyguards and Zhang. Everyone is accounted for here. If Zhang was onto our surveillance, then there was a good chance he alerted his contact at the conference. They would have fled together in order to complete the exchange.”

She tried to glance to the bodies, but he restrained her with his gun. “You can’t think it was me?” she said, with a half laugh.

He pointed his free hand, never letting his weapon drop. “I recognize the handiwork of a forty-five, like the Sig Sauer you carry.”

“Zhang took it from me. Painter, you’re being paranoid. I-”

He reached to a pocket and pulled out the bug he found taped to the elevator wall. He held it toward her.

She stiffened, but refused to look at it.

“No blood, Cassandra. Not a trace. Which means you never implanted it like you were supposed to.”

A hard edge sharpened her face.

“The computer code?”

She simply stared at him, coldly dispassionate now. “You know I can’t.”

He searched this stranger’s face for the partner he knew, but she was long gone. There was no remorse, no guilt, only determination. He didn’t have the time or the stomach to break her. He nodded to Fenton. “Have your men cuff her. Keep her under constant guard.”

As she was being secured, she called over to him. Her words were plainly spoken. “Painter, you’d best watch your back. You have no idea what a shitload of pain you just stepped into.”

He picked up the computer suitcase and walked away.

“You’re swimmin’ in the deep end, Painter. And there are goddamn sharks all around you, circling and circling.”

He ignored her and crossed toward the north entrance. He had to admit something to himself: he simply didn’t understand women.

Before he could escape back inside, a tall figure in a sheriff’s hat blocked his way. It was one of the MP Tribal Police. “Commander Crowe?”

“Yes?”

“We have an urgent call dispatched through our offices holding for you.”

His brow crinkled. “Who from?”

“From an Admiral Rector, sir. You can speak to him on one of our radios.”

Painter frowned. Admiral Tony “The Tiger” Rector was the director of DARPA, his commander in chief. Painter had never spoken to him, only seen his name on memos and letters. Had word already reached Washington about the mess out here?
