HE COSTA DEL Sol had lived up to its name today.

Robie wore a straw-colored narrow-brim hat, a white T-shirt, a blue jacket, faded jeans, and sandals. There was three days’ worth of stubble on his tanned face. He was on holiday, or at least looked to be.

Robie boarded the large, bulky ferry to cross the Strait of Gibraltar. He looked back to the mountains rising along the rugged and imposing Spanish coastline. The juxtaposition of the high rock to the blue Med was captivating. He admired it for a few seconds and then turned away, forgetting the image just as quickly. He had other things occupying his mind.

The high-speed ferry headed to Morocco. It pitched and swayed like a metronome as it left Tarifa Harbor on its way to Tangier. Once it gathered speed and hit the open waters, the ride smoothed out. The belly of the ferry was filled with cars, buses, and tractor-trailers. The rest was crammed with passengers eating, playing video games in an arcade, and purchasing duty-free cigarettes and perfume by the carload.

Robie sat in his seat and admired the view, or at least pretended to. The strait was only nine miles wide and the ride would take only about forty minutes. Not a lot of time to contemplate anything. He spent it alternately gazing out at the waters of the Med and studying the other passengers. They were mostly tourists, eager to say they had been to Africa, although Robie knew that Morocco was very different from what most people probably would think when they imagined Africa.

He walked off the ferry in Tangier. Buses, taxis, and tour guides awaited the masses. Robie bypassed them all and left the port on foot. He entered the main street of the town and was instantly besieged by peddlers, beggars, and shopkeepers. Children pulled on his jacket, asking for money. He directed his gaze down and kept walking.

He passed through the congested spice market. At one corner he nearly stepped on an elderly woman who looked to have fallen asleep while holding on to a few loaves of bread for sale. This had probably been her entire life, thought Robie. This corner, and a few loaves of bread for sale. Her clothes were dirty, her skin the same. She was soft and plump but malnourished, as was often the case. He bent down and put some coins in her hand. Her gnarled fingers closed around them.

She thanked him in her language. He said “you’re welcome” in his. They both somehow understood the exchange.

He walked on, increasing his pace, taking any steps he encountered two and three at a time. He passed by snake charmers who placed exotically colored and defanged reptiles around the necks of sunburned tourists. They wouldn’t take the snakes off unless five euros were placed in their hands.

A nice racket if one could get it, thought Robie.

His destination was a room over a restaurant promising authentic local food. It was a tourist trap, he knew. The food was generic, the beer warm, and the service indifferent. The bus guides led unsuspecting folks there and then hurried elsewhere to eat a far better meal.

He headed up the stairs, unlocked the door to the room with the key he had previously been given, and locked the door behind him. He looked around. Bed, chair, window. All he needed.

He put his hat on the bed, looked out the window, and eyed his watch. It was eleven a.m. local time.

The flash drive had long since been destroyed. The plan was in place and the movements practiced at a mock facility back in the States that was the exact duplicate of his target. Now he simply had to wait, the hardest part of all.

He sat on the bed, massaged his neck, working out kinks from the long trip by plane and boat. This time the target was no idiot like Rivera. He was a cautious man with professional assets who wouldn’t spray bullets around. This one would be harder, or at least it should be.

Robie had brought nothing with him from Spain because he had to pass through customs to get on the ferry. A weapon found in a bag by Spanish police would have been something more than problematic. But everything he needed would be in Tangier.

He took off his jacket, lay back on the bed, and let the heat from the outside make him drowsy. He closed his eyes, knowing he would open them again in four hours. The sounds from the street receded as he fell asleep. When he woke, nearly four hours had passed and it was the hottest part of the day. He wiped sweat from his face and went back to the window, looked out. He watched big tour buses navigate streets never built for anything so large or cumbersome. The sidewalks were full of people, both locals and visitors.

He waited another hour and then left his room. On the street he turned east and double-timed it. In a few seconds he was lost in the hustle and bustle of the old city. He would collect what he needed and move on. All these items would be for the mission. He had traveled to thirty-seven countries and had never purchased a single souvenir.

Seven hours later it was quite dark. Robie approached the large, stark facility from the west. Over his back was slung a hardened case and a knapsack with water, a pee jar, and provisions. He did not plan on leaving here for the next three days. He looked around, taking in the smells of a third-world country. The air was also heavy with the threat of rain. That would not bother him. This task was an inside job.

He checked his watch and heard it approach. He ducked down behind a cluster of barrels. The truck passed by him and stopped. He approached it from the rear. Three strides later he was under it, holding on to metal jutting out from its underside. The truck drove on and then stopped once more. There was a long, wrenching sound of metal on metal. It started up again with a jolt that nearly caused Robie to lose his grip.

Fifty feet later the truck stopped once more. The doors opened, feet touched the floor. Doors clunked shut. Footsteps headed off. The wrenching sound came again. Then hardened locks were clicked into place. There was quiet, except for the footfalls of the perimeter patrol that would be there 24/7 for at least the next three days.

Robie timed it so he was out from under the truck and racing away just as the wrenching sounds stopped. The facility technically had been cleared and put in lockdown. This was the only opportunity Robie had to get in. Mission accomplished, at least this part.

He took the steps three at a time, the hard-sided case hitting him in the back.

Next came the race against the clock.

He reached the top, grabbed the girder, and did a monkey crawl, hand over hand, to the targeted spot. He swung to the left and then the right and then made his leap.

He landed nearly silently on metal and skittered to a spot eighty feet distant, in one of the darkest corners of the space.

He did so with five seconds to spare.

The lights clicked off and the alarms came on. The interior space was instantly crisscrossed with beams of energy that were invisible to the naked eye. But if anything with a pulse touched them sirens would go off. All intruders found would be executed. It was just that sort of place.

Robie turned over on his back, his face to the ceiling.

Three days, or seventy-two hours, to go.

It seemed his entire existence was one uninterrupted countdown.
