Lyons did not chance walking on the road. He slung his Atchisson over his back and snaked across the asphalt to the other side. Clutching at roots, his soft-soled shoes finding footholds in the rocks, he went hand-over-hand up the embankment.

The exertion made him gasp. He slowed his climbing. He disciplined his breathing, pulling down long, deep gulps of moist air, matching his breath cycles to his motions. He pulled himself through the roots and ferns and rocks very quietly, only the slight sound of falling pebbles and dirt breaking the silence.

Voices came from above. He froze, listening for the source. In the tangle of pines and oaks growing from the near-vertical mountainside, some of the voices seemed distant, others near. He inched up the slope as if crawling up a wall.

An obstacle stopped him. He made out the rusting, dismantled form of a car — doors and interior and motor gone — propped against a pine. A broken guardrail lay amidst cut branches. He could not continue to the road above without thrashing through the debris. He looked to the sides. More debris blocked him. For years, road maintainance crews had simply dumped trash and tree trimmings downhill.

He looked at the pines. Fifty to sixty to a hundred feet tall, the trees rose high above the road. Branches grew from the trunks in all directions.

Lyons climbed silently up a pine, keeping the trunk between him and the voices. In seconds, he was looking down at the road.

The mist glowed red with taillights. Soldiers in the camouflage uniform of the Army of Guatemala paced the road in front of the stopped bus. Flashlights swept the interior of the vehicle, casting silhouettes against the windows. Soldiers checked identity cards.

Laughter came from the pickup trucks and a troop carrier parked against the side of the mountain. Lyons heard English.
