The plane rolled to a stop, and almost instantly Zubair felt the resumption of his stomach's volcanic action. A film of sweat appeared on his forehead and upper lip. The scientist mopped his brow and then his upper lip with a handkerchief. He felt naked without his mustache, but they had made him shave that also. They wanted him to assimilate, to blend in as much as possible. His hair was cut short and styled for the first time in his life. His glasses had been replaced with contacts, and they had purchased for him a new set of clothes and expensive Tumi luggage in Australia.

The passengers began standing, opening compartments and gathering their things. Afraid to move and give away his nervousness, Zubair was in no hurry. Once most of the other passengers were gone, he retrieved his computer bag and made his way down the narrow stairs to the main body of the plane. He half expected to see a group of men in suits waiting for him, but thankfully there were none. He'd been warned that the Americans had gotten much better at intercepting people who were trying to illegally enter their country.

Two female flight attendants with whorish makeup and skirts that were far too short stood by the door. They thanked him for flying Qantas. Despite what his trainers had told him, Zubair ignored the women, refusing to look them in the eye. Fortunately for him his diminutive stature made him seem shy rather than hostile. Zubair was just five and a half feet tall, and weighed a svelte 142 pounds. With his mustache shaved he easily passed for someone five to ten years younger than his twenty-nine years.

He stepped into the Jetway, joining the stampede for baggage claim and customs and sandwiched between the business-class and economy customers. The stress of the situation and the heat of the enclosed Jetway triggered the scientist's sweat glands, sending them into overdrive. Within seconds salty perspiration dampened every inch of his skin.

Zubair felt trapped, as if he was on a conveyor belt headed toward his own execution. There was no turning back. Passengers continued to pour off the plane, pushing forward, moving through the confined tunnel toward U.S. Customs agents who would ask probing questions. Zubair suddenly wished he had taken the sedative that they had given him to calm his nerves. He had thrown the pills away at the Sydney airport. Allah would never approve of him taking a mood-altering drug. Now he desperately wished he'd kept the little pills, just to get him through this part.

They left the Jetway and at least for a moment things got better. The extra space and cooler air of the terminal felt less confining. The stampede of people continued down a set of stairs to a boxed-in area where they began to cue up in multiple lines to present passports and port of entry/declaration forms to U.S. Customs agents. Zubair got in one of the lines being handled by a man. As long as he had the choice he would not deal with a woman.

When it was his turn he stepped up to the counter, his wheeled black carry-on bag in tow, and handed the agent his passport and paperwork. The man eyed the passport first, flipping through several pages to see where the visitor had been over the past few years.

"First time to America?"

"Yes," Zubair answered with his accented English.

"How long have you been an Australian citizen?"

"Three years."

"And your occupation?" The agent flipped through the paperwork for verification.

"I'm a computer programmer."

"Purpose of your visit?" the man asked in a no-nonsense tone.

Zubair couldn't believe his luck. So far the man hadn't even bothered to look at him. "I'm here for business."

"Traveling alone?"

"Yes."

The agent stamped the passport and handed it back to Zubair, for the first time giving him a good look and noticing the beads of perspiration on his upper lip and forehead. "Are you feeling all right?"

"Ah...yes," answered Zubair, mopping his brow with his handkerchief. "I just don't like to travel."

The Customs agent studied him for a moment longer. He then handed Zubair his passport and paperwork with his right hand, and with his left, he pressed a button letting his colleagues in the watch room know that he had someone they should run through the facial recognition system. It was nothing alarming. Just a standard precaution.

Zubair took his documents and proceeded to the baggage carousel where his one piece of luggage with its bright orange business-class tag was already waiting for him. He grabbed the bag and went to the next checkpoint where he was met by a woman several inches taller than him.

She gestured for him to go the right and said, "Please place your bags on the table and remove any locks."

Zubair did as he was told, with the sickening feeling that he was about to be discovered. He'd been told there was a good chance that they would ask him to open his bags, but there were others who were being allowed to pass by this checkpoint without any inspection at all. Why couldn't he be one of them?

He stood nervously as the woman began looking through each compartment of his two cases. He reminded himself that there was nothing for her to find. The only items that could implicate him were several encrypted files on his laptop, but they would need someone from their notorious National Security Agency to decipher those. After several minutes the woman closed the bags and told Zubair he was free to go.

Astonished, Zubair grabbed his bags and handed his paperwork to another agent. The man then gestured for him to leave the secure area. Zubair placed his passport in his pocket, and looked down the long hallway in front of him. Up ahead he could see daylight. As he wheeled his bags down the hallway he could barely believe he'd made it through customs. Giddy with excitement he quickened his pace. He'd defeated the gauntlet of American security, and there was nothing they could do to stop him now. He was free to roam America and do his work.Youmud Deen, the day of judgment, was fast approaching, and Zubair would strike a mighty blow for Islam.

PAKISTAN

Four super-quiet MH-6 Little Bird helicopters wound their way through the craggy canyon at seventy miles per hour in near total darkness. Sixteen of the most highly trained and seasoned soldiers the world had ever seen rode two on each side of the small agile helicopters, their scuffed and worn combat boots dangling in the cool mountain air, their eyes protected by clear goggles. The uniforms varied slightly; some wore flight suits, while others had chosen the desert camouflage version of the U.S. army's standard battle dress, or BDUs. They all wore body armor, knee and elbow pads, and a specialized cut-down helmet with night-vision goggles affixed in a pop-down pop-up mode.

They carried an arsenal of weapons, ranging from pistols, to shotguns, to sniping rifles, to light and heavy machine guns. None of them had bothered to bring silencers. Their presence would be known within seconds of their arrival, and once they hit the ground there was a chance they'd need every extra bullet and grenade they could carry. They were heading directly into the thick of things.

The nimble helicopters ducked and bucked their way through the cool mountain air like some sadistic amusement park ride, but the men sitting on the specially designed platforms were used to it. They were miles away from civilization in a foreign land that was among the most desolate and inhospitable places on earth, and every last one of them was eagerly anticipating the battle that lay ahead.

A voice crackled over their earpieces announcing that they were one minute out from the target. In the resulting flurry of activity, optic rifle sights, red laser dot pointers, and night-vision goggles, or NVGs, were turned on, gear was shifted, and those who weren't already cocked and locked did so.
