“Loose dogs are a thing of the past. They’re unpredictable, noisy, and often end up attacking the wrong person. Dogs are now only used for tracking. What we have to watch out for will be far more subtle.”
They crossed the expanse of concrete. Nocturnal animals rustled in the foliage as they passed. At the far end of the courtyard was a grassy alley between two rows of ruined buildings, the heaps of masonry covered with ivy that, in the darkness, looked like spreading stains. Pendergast proceeded more cautiously now, using a small, hooded flashlight to illuminate their way. Halfway along the alley he paused, knelt, and examined the ground. Then he picked up a branch and gave a little poke to the grass ahead. He prodded harder, and the stick suddenly broke through into space.
“A pit,” he said. “Notice that, with these ruins flanking either side, this alley is the only way to proceed.”
“A booby trap?”
“Undoubtedly. But disguised to look like some part of the old factory, so that when the intruder falls in and is killed, nobody would be blamed.”
“How did you spot it?”
“Lack of boar tracks.” Pendergast carefully withdrew the stick and turned. “We shall have to make our way through one of these ruined laboratories. Take care: there may still be the odd bottle of nitroglycerin around, strategically placed to snag the unwary. We should consider this the next ring of security, Vincent; we must be both quiet and vigilant.”
They entered a dark doorway and Pendergast flashed his hooded light around. The floor was covered with broken glass, rusty pieces of metal, broken tile, and bricks. Pendergast paused, then signaled to D’Agosta to back out.
Two minutes later they were in the concrete courtyard.
“What was wrong?” D’Agosta asked.
“Too much broken glass, too evenly spread, and the glass was too modern to be from the original factory. A noise trap, with sensors ready to pick up the telltale crunch of human feet. Motion sensors, too, I expect.”
In the greenish glow of his lantern, Pendergast’s face seemed troubled.
“What now?”
“Back to the pit.”
They circled back around to the alleyway and Pendergast crept forward alone, prodding with a stick until he’d located the pit. Then he lay on his stomach, carefully parted the thick grass and vegetation, and shone his light into the dark hole. A moment later he withdrew, snapping off his light.
“Wait here.”
And then he was gone, melting into the night.
D’Agosta waited. Pendergast hadn’t told him to remain still and silent; he hadn’t needed to. He crouched in the inky darkness, barely daring to breathe. Five minutes passed. Left alone, the tension began to take its toll. D’Agosta could feel his heart pounding in his chest.
Relax.
And then—as suddenly and silently as he had disappeared—Pendergast was back, a long plank in his hands. He laid it across the brushy opening, then turned to D’Agosta. “Beyond this, no talking unless absolutely necessary. Follow my lead.”
D’Agosta nodded.
They crossed the wobbly plank, one after the other. On the far side, the brush was thicker, presenting a dark wall. Pendergast moved forward, probed with his sensor, sniffed. He briefly turned on the light, then turned it off again. They moved parallel to the brushy area, then veered into it on what appeared to be an animal trail.
The boars are saving our ass, D’Agosta thought.
They crept slowly through the thick brush. A brick wall loomed to their right: a blast wall, judging by its massiveness. In one place it had been knocked down by what D’Agosta guessed was an old explosion. They moved through this gap, still following the boar trail. D’Agosta could barely see Pendergast, and could hear even less: the man moved as silently as a leopard.
The trail petered out in a large meadow less overgrown than the others they had passed. Pendergast paused to reconnoiter, motioning for D’Agosta to stay back. At the far end lay the dark silhouette of more wrecked buildings and, beyond that, the faint glow of light.
Pendergast slipped a pack of cigarettes out of his pocket. Turning back toward D’Agosta, and very carefully shielding a cigarette with his hands, he lit up. D’Agosta watched, astonished. Pendergast inhaled lazily, turned, and blew out a stream of smoke.
Not three feet in front of them, the drifting smoke revealed a brilliant beam of blue light: a laser. It was set just high enough to clear the back of a boar.
Pendergast got down on his stomach and began to slither forward through the tall grass, motioning D’Agosta to do likewise.
