Uh-oh. Vance felt the tracks suddenly shiver. Then with what sounded like a painful grind of metal on metal, the gantry started moving again. They'd decided to override the safety shutoff.
Okay, he thought, back to the original plan. He turned and retraced his steps to the place where he had left the gelignite, feeling along the track until his fingers touched it. It was still in place, but there was no time now to set up a fuse.
Which meant there was only one other way to blow it.
Quickly he secured the diamond-shaped patch more tightly around the steel, then looked up to check the gantry. It was now about five meters away, its wheels inching along the rails with a ponderous inevitability as its electric motors hummed.
He pulled out his sailor's tin of matches and withdrew one. Relieved it was still dry, he scraped the match across the bottom of the can and it flamed in the dark. Next he quickly pressed the wooden end into the soft gelignite, making a target he could see from a distance.
After checking it one last time, he rose and dashed for the safety of the nearest shed, pulling the Uzi from his belt and chambering a round.
He leaned against a darkened wall and took careful aim, on semi-auto. The gantry was only a meter away from the charge when he finally squeezed off a round. It kicked up a spray of gravel next to the rails, the small stones glistening in the floodlights like small shining stars as they erupted slightly to the left of where he had placed the charge.
Damn. He knew the match could be seen, as well as the flare of the Uzi, but maybe nobody was watching. In any case, he adjusted his aim and quickly fired again. But this time he had moved the sight too far to the right. Again the gravel splayed, another sparkle under the lights, but once more nothing happened.
Now the gantry's wheels were about to pass directly over the explosive. If the thing was going to be immobilized, he had one shot left. He took careful aim and squeezed the trigger…
To the sound of a dull click. His last round had misfired.
