Pitt slipped off one sneaker and retrieved his Doxa dive watch where he'd hidden it under his sole. He slipped it back on his wrist and held it up in front of Giordino. 'One-twenty in the morning.'
'Nothing like an early start.'
Pitt shifted into first gear and eased out the clutch, steering the truck into the exit tunnel, moving only slightly faster than idle so the sound of the exhaust wouldn't travel up the tunnel to suspicious ears.
The walls were so close they nearly touched the sides of the truck. Pitt cared little about scratching the paint. His main concern was scraping noises that might have drawn attention, but once they broke into the open and entered the narrow ravine, he shifted up, mashed the accelerator to the floor, and switched on the headlights. The Renault plunged through the tight ravine, bouncing crazily and trailing a swirling cloud of dust.
Pitt mentally recalled where the soft spots in the sand were located during the trip through the canyon. He had surveyed the nearby landmarks when he was required to push the truck to firmer ground. Now he threw the truck through the tight crack of the rocky plateau with reckless abandon, hurtling across the yielding sand patches that grabbed at the tires but failed to bog them down because of the truck's rapid momentum.
He took no notice of the smell of freedom, the cold night air of the desert, nor did he waste a quick look at the stars above. Each kilometer they put between them and pursuit was golden, every minute precious. He drove like a demon, pushing the truck to its limits.
Giordino made no complaints, no appeals to slow down. He put his implicit faith in Pitt, propped his fit against the dashboard, and gripped the bottom of his seat, teeth clenched against the jarring ride, eyes fixed on the barely distinct tire tracks looming in the darkness under the steep walls of the canyon.
Abruptly the headlights showed empty flatlands ahead as they sped out into flat desert. Only then did Pitt look up at the sky, pick out the north star, and aim the radiator cap of the truck toward the east.
They had crossed the point of no return in a suicidal attempt with odds so high that failure seemed inevitable. But Pitt wouldn't have had it any other way. There could be no stopping until they reached water or rescue.
Ahead lay 400 kilometers of desert, inviting, ominous, and deadly. The race for survival was on.
For the five hours of remaining darkness, Pitt spun the truck's wheels through the awesome wilderness of sand where time had little meaning. This was truly a land of no compromise that chilled with its cold mornings, choked with its fine sand, and baked with a sun that seemed magnified by a crystal atmosphere. He felt as if he had entered a world not of his universe.
They were moving through a section of the Sahara called the Tanezrouft, huge sprawling badlands with almost 200,000 square kilometers of bleak, grotesque wasteland broken only by a few rugged escarpments and an occasional sea of sand dunes that relentlessly moved across the flats like ghostly armies of veiled phantoms.
This was the desert primeval without a weed in sight.
And yet, there was life. Moths fluttered about the headlights. A pair of ravens, the desert's scavenging, cleaning service, disturbed by the approach of the truck took wing and squawked in annoyance. Large black scarabs scampered over the sand to escape the tires as did an occasional scorpion and tiny green lizard.
Pitt found it easy to become intimidated by the surrounding void, by the hundreds of kilometers they had yet to travel, the almost certain hunger, thirst, and privations that remained to be endured. His only solace was the steady roar of the Renault's engine. It hadn't skipped a beat since leaving the mines, and the four-wheel-drive performed flawlessly, surging through soft spots Pitt was sure would bog them down. On four occasions he was forced to drive into deep, narrow dry washes with sloping soft gravel banks, barely making it up and over the opposite edge in low gear. Often he found no way to dodge sudden drop-offs or boulders and having to risk going over seeming impossible barriers, but somehow the sturdy Renault pulled them through.
They took no time to stop, get out, and stretch their legs. They would get enough of walking later when they abandoned the truck. They even took calls of nature on the fly without braking.
'How far have we traveled?' asked Giordino.
Pitt glanced at the odometer. 'A hundred and two kilometers.'
Giordino looked at him. 'You take the wrong short cut or are we going in circles? We should have covered almost 200 kilometers by now. Are we lost?'
'We're on course,' said Pitt confidently. 'Blame it on Fairweather's directions. He gave distances as the crow flies. No crow with half a brain would be flying around the desert if he could be attacking a scarecrow in an Iowa cornfield. Impossible to maintain a straight line when we've already had to detour 40 kilometers to avoid two deep ravines and a herd of sand dunes.'
Giordino stirred uncomfortably. 'Why do I get a sinking feeling we're about to hike a lot further than 100 kilometers across no-man's-land.'
'Not a cheery thought,' Pitt agreed.
'Be light soon. We'll lose the stars to navigate by.'
'Don't need them. I finally remembered how to build a do-it-yourself compass straight out of the Army Field Manual.'
'Glad to hear it,' Giordino yawned. 'What does the fuel gauge read?'
'Slightly over half a tank left.'
Giordino turned and looked back at the Tuareg they had tied up in the truck bed. 'Our friend looks about as happy as a shanghaied sailor.'
'He doesn't know it yet, but he's our ticket to evade pursuit,' answered Pitt.
'The devious mind again. It never stops churning.'
Pitt briefly stared up at the sickle moon. He would have preferred a full phase, but he was thankful for what little light it sent down as he drove the truck across a terrain equal to a lunar landscape. He shifted gears and strained his eyes on the uneven ground revealed by the headlights. Then suddenly the desert smoothed out and began to sparkle like fireworks.
The Renault rolled onto a huge dry lake with crystal deposits that reflected the twin beams from the headlights like prisms in rainbow colors. Pitt opened the Renault up in high gear and felt exhilarated to be speeding over a firm, flat surface at nearly 90 kilometers an hour.
The desert floor seemed to reach into infinity, the early morning stars falling below the horizon line as if the great brink of a flat world abruptly fell away into space. The sky looked as if it was closing in all around them like the four walls and ceiling of a small room. An unnerving sense of disorientation gripped Pitt. Yet he was following nearly the same parallel as Havana, Cuba, so the big dipper was still above the horizon. He continually used Polaris as a base point to line up a star to the east and then steered toward it.
Hour passed upon monotonous hour as the crystal lake gave way to low, boulder-strewn hills. Pitt could not recall having experienced such a heavy shroud of monotony. His only respite was a small peak off his left to the north that rose like an island in the middle of a vast and sterile sea.
Giordino took over the driving chore as the sun burst from the horizon as if shot from a cannon. There it seemed to hang without moving throughout the day until suddenly falling like a rock shortly before sunset. Shadows stretched far into the distance or did not exist. There was no in-between.
An hour after daylight, Pitt stopped the truck and searched around the cargo bed until he found a loose pipe about a meter in length. Then he stepped to the ground and pushed the pipe into the sand until it stood vertical and cast a shadow. Picking up two small stones, he placed one at the tip of the shadow.
'Is this your poor man's compass?' asked Giordino, studying Pitt's actions from the shade of the truck.
'Observe the master at work.' He joined Giordino and waited approximately twelve minutes before marking the distance the shadow had traveled with another stone. Next he drew a straight line from the first stone to the second and extended it about half a meter beyond. He then stood with the toe of his left foot at the first rock and toe of his right where the line ended. Lifting his left arm and pointing straight ahead, he said, 'That's north.' Then he extended his right arm to the side. 'East to the Trans-Saharan Track.'
Giordino sighted down Pitt's outstretched right arm and hand. 'I see a dune in that direction we can use as a reference point.'
They moved on, repeating the process every hour. At about nine o'clock the wind began to blow from the southeast, swirling the sand in clouds that cut visibility to less than 200 meters. By ten, the heated wind had increased and. was seeping into the cab of the truck despite the rolled-up windows. Swept up in small gusts, the sand rose and twisted' like whirling dervishes.
The mercury jumped and fell like a pogo stick. This day the temperature rose from 15 degrees C (60
