It swept right over them, banked slightly, sank down toward the pad, hovered for a few moments, and then settled to the concrete. A few seconds later the rotor stopped, the passenger door opened, and a man climbed down to the pad. Even at half a kilometer without binoculars, Pitt correctly guessed the identity of the figure who vigorously strode toward the office complex.
"I think our friend has returned to haunt us," he said.
Giordino cupped his hands around his eyes and squinted. "Too far to tell for sure, but I do believe you're right. A shame he didn't bring the piano player from the houseboat."
"Can't you get her out of your mind?"
Giordino looked at Pitt with a hurt expression. "Why would I want to?"
"You don't even know her name."
"Love will conquer all," Giordino said moodily.
"Then conquer your amorous thoughts and let's rest up until nightfall. Then we've got a train to catch."
They had bypassed the well described by the old prospector when the Oued Zarit's former riverbed meandered in a different direction. The soft drinks were gone and their supply of water was down to 2 liters, slightly more than 2 quarts. But they divided and drank it all to avoid dehydration, trusting in finding a source near the project.
They parked the Voisin in a small ravine a kilometer south of the abandoned fort that sat beside the railroad, then burrowed into the sand under the car, achieving a small measure of shelter from the sweltering heat. Giordino dropped off quickly, but Pitt's mind was too restless for sleep.
The night sweeps across the desert quickly. The dusk is short before the darkness. There was a strange stillness, the only sound coming from the faint tick of the Voisin's engine as it cooled. The dry desert air became cleansed from the heat and blowing sand of the day and magnified the great storm of stars that gleamed in an obsidian sky. They were so sharp and distinct Pitt could actually separate the red stars from the blue and green. He had never seen such a cosmic display, even on the open sea.
They covered the car in the gulch for the last time and hiked under the stars to the fort, careful to sweep their tracks with a palm frond as they proceeded. They passed by the old Legion graveyard and scouted around the 10-meter high walls until they came to the main gate. The giant wooden doors, solid and bleached white by the sun, stood slightly ajar. They entered and found themselves on the dark and deserted parade ground.
It took little for their imaginations to see a ghostly formation of French Foreign Legion footsloggers standing at attention in their blue tunics, baggy white trousers, and white kepi caps, before marching out onto the burning sands to fight a horde of Tuaregs.
The actual size of the former outpost was small by most Foreign Legion standards. The walls, each 30 meters in length, were formed in a perfect square. They were a good 3 meters thick at the base with staggered bastions at the top to protect the defenders. The entire structure could have easily been manned by no more than fifty men.
The interior showed the usual signs of neglect. Debris left by the departing French troops and bits of trash left by desert wanderers who took advantage of the fort's walls during sandstorms lay scattered on the ground and in the barracks quarters. Materials left over by construction workers during the building of the railroad were stacked against one walclass="underline" concrete railroad ties, various tools, several drums of diesel oil, and a forklift that looked in surprisingly good condition.
"How'd you like to be stationed in this place for a year?" muttered Giordino.
"Not for a week," said Pitt, surveying the fort.
While they waited for a train, time dragged by with tormenting slowness. The odds were good to excellent that the chemical compound Gunn had discovered as the cause of the exploding red tide was filtering out of the solar detoxification plant. After their run-in with Massarde, Pitt knew that a knock on the door and a cheery request to inspect the property would not be met with open arms and a hearty handshake. They had to worm their way in and find positive evidence.
There was something far more sinister going on at Fort Foureau. To all appearances it was contributing to the battle against the world's millions of tons of toxic waste. But scratch the surface, Pitt thought, and we shall see what we shall see.
He was calculating their chances of passing through the security station and getting out again as extremely bleak, when his ears picked up a sound in the distance. Giordino came out of alight sleep and heard it too.
They looked at each other wordlessly and came to their feet.
"An inbound train," said Giordino.
Pitt held up his Doxa dive watch and studied the luminous hands. "Eleven-twenty. Plenty of time to do our inspection act and get out before daylight."
"Providing there's a scheduled outbound," Giordino cautioned.
"So far they've been tooting by like clockwork every three hours. Like Mussolini, Massarde keeps them running on time." Pitt stood and brushed off the sand. "Off we go. I don't want to be left standing on an empty track."
"I wouldn't mind."
"Keep low," Pitt warned. "The desert reflects starlight, and the ground is open between the fort and the tracks."
"I'll flit through the night like a bat," Giordino assured him. "But if a drooling dog with big fangs or beady-eyed guard with an automatic weapon has other ideas?"
"We prove our suspicions that Fort Foureau is a facade."
Pitt said firmly, "One of us has to escape and alert Sandecker, even if it means sacrificing one for the other."
A thoughtful expression crossed Giordino's face and he stared at Pitt without saying anything. Then the air horn on the lead diesel locomotive sounded to announce its impending arrival at the security station. He nodded at the tracks. "We'd better hurry."
Pitt nodded silently. Then they stepped through the fort's big gate and ran toward the tracks.
An abandoned Renault truck sat forlornly about halfway between the fort and the railroad tracks. Everything that could be stripped from the body and chassis was long gone. Tires and wheels, engine, transmission and differential, even the windshield and doors were removed for parts or sold for scrap, hauled off by camel to Gao or Timbuktu by an enterprising merchant.
To Pitt and Giordino, as they huddled behind the truck to avoid being caught in the glare of the light on the forward diesel engine, the deserted loneliness of an object used by man and then forgotten and discarded was overwhelming. But it made for the perfect cover as the long freight train approached.
The revolving, light above the engine swept across the desert and illuminated every rock and every blade of sparse grass for almost a kilometer. They crouched out of the beam until the engines thundered past at what Pitt estimated as nearly 50 kilometers an hour. The engineers were braking now as they prepared to enter the security station. Pitt waited patiently as the train's speed tapered off. By the time the last cars in line reached the abandoned truck, he estimated, the train's momentum would be down to about I S kilometers, a speed slow enough for them to run alongside and board.
They left the safety of the scrapped truck and dashed the final few meters to the roadbed, hunching down and observing the flatbed cars that carried huge removable cargo containers as they rumbled toward Fort Foureau. The end car was in sight now, not an ordinary-type caboose for the train crew, but an armored car with turreted heavy machine guns manned by corporate security guards. Massarde ran a tight operation, Pitt thought. The escorts were probably professional mercenaries hired out at above average wages.
Why the ironbound security? Most governments looked upon chemical waste as a nuisance. Sabotage or an accidental spill in the middle of the desert would go almost unnoticed in the international media or environmentalist circles. Who were they guarding it from? Certainly not the occasional bandit or terrorist.
