There was no need for either of them to speak. They began looking for a place to cross the river. All the time they searched they could hear the machine behind them, above them, humming safely out of their range.
The sun was low in the sky when they heard the second humming. The humming grew until it was a throbbing that covered the weaker sound of the robot and chilled Nelson.
"The patrol," he said, pushing the girl toward the forest. "Back into the trees. We're going to have to fight it out with them."
They ran into the trees. The throbbing stopped and behind them, Nelson could hear the sounds made by men thrashing through the undergrowth. His palms were wet; he wiped them on his shirt front. The impending contact with the patrol gave him a calmness as always, and he picked out a thicket where he believed he could make some sort of stand.
He reached the thicket with Glynnis behind him. Her gun was out. He signed to her to lower the intensity of the gun; she caught on. He watched her face. It was like a mask.
Nelson listened to the sounds of the approaching patrolmen. Five or six, he decided. Plus a guard back at the flier. He'd figure on eight, in all, he decided. Then the first one showed behind some bushes.
Nelson touched Glynnis' arm in a signal to wait. The patrolman looked around, searching too intensely to find anything. He was young. Nelson didn't think he would uncover their whereabouts and for a moment debated letting him pass.
But he didn't want to be surrounded. He pulled his gun up and sighted carefully before squeezing the trigger. In the tenth of a second before the patrolman burst into flames, the blast produced a blast circle that grew to the size of a basketball in his midsection. The patrolman fell without screaming.
The others were there now. Most of them were young and two rushed forward at the sight of their companion's death, to die like heroes. The others wisely sought cover. Nelson decided that the thicket wasn't as safe as he'd hoped. One of the patrolmen was doing a good job with an energizer, coming closer with each shot, before Nelson finally saw where he was, and fired at him. Nelson saw the trunk of a large fallen tree and pointed to it for Glynnis' benefit. She nodded.
There was cover most of the way. Nelson went first, crouching low to the ground and running with the ease of a cat. He made the log and began firing to cover Glynnis. He saw her coming, out of the corner of his eye, then concentrated on covering her with firepower. Suddenly the girl let out a startled yell and he saw her sprawl to the ground, tripping over a root. He called her name and without thinking leaped to his feet to run to help her. He was halfway there when the patrolman came into range. Nelson realized what he had done. Glynnis was already on her feet and running. Cursing himself, Nelson jerked his gun around, but it was too late. An energizer blast exploded the ground beneath him and he felt himself hurtling over backwards. He could only see blackness and the bright, quick, flashing of pin-point light in it. Then, he was falling, spinning....
