“Mom?” Chris said, Meaning: What now?
The arroyo would have scores of tributaries spread out across the desert, and many of those tributaries would have tributaries of their own. The drainage network was like a maze. They could not hide in it forever, but perhaps by putting a few branches of the system between themselves and their pursuers, they would gain time to plan an ambush.
She said, “Run, baby. Follow the main arroyo, take the first right-hand branch you come to, and wait there for me.”
“What’re you going to do?”
“I’ll wait for them to look over the edge up there,” she said, pointing to the top of the palisades, “then pick them off if I can. Now go, go.”
He ran.
Leaving the canister of Vexxon in plain sight, Laura returned to the wall of the arroyo down which they’d slid. She went to a different vertical channel, however, one that was carved deeper into the wall, had less of a slope, and was half-blocked at its midpoint by a mesquite bush. She stood in the bottom of that deep hollow, confident that the bush overhead blocked their view of her from the desert above.
To the east, Chris vanished around a turn into a tributary of the main channel.
A moment later she heard voices. She waited, waited, giving them time to feel confident that both she and Chris were gone. Then she stepped out from the erosion channel in the arroyo wall, turned, and swept the top of the cliff with bullets.
Four men were there, peering down, and she killed the first two, but the third and fourth leaped backward, out of sight before the arc of fire reached them. One of the bodies lay at the top of the arroyo wall, one arm and leg over the brink. The other fell all the way to the floor of the channel, losing his sunglasses on the way.
March 16, 1944. The institute.
When the bottle with the message did not bounce back to him, Stefan was reasonably confident that it had reached Laura before she had been killed, only seconds after he had first departed for 1944.
Now he returned to the programmer’s desk and set to work on the calculations that would return him to the desert a few minutes after his previous arrival there. He could make that trip because he would be arriving subsequent to his previous hasty departure, and there would be no possibility of encountering himself, no paradox.
Again the calculations were not terribly difficult because he needed only to work forward from the numbers that the IBM PC had provided him. Though he knew that the time he spent here was not passing in equal measure in the desert of 1989, he was eager to rejoin Laura nevertheless. Even if she had taken the advice of the message in the bottle, even if the future he had seen had been changed and she was still alive, she would have to deal with those SS gunmen, and she would need help.
In forty minutes he had the numbers that he required, and he reprogrammed the gate.
Again he opened the panel on the jaunt recorder and tore the evidence off that spool of paper.
Carrying the Uzi and the pistol, gritting his teeth as the dull throbbing in his half-healed shoulder grew worse, he entered the gate.
Lugging both the Vexxon canister and the Uzi, Laura joined Chris in the narrower tributary off the main channel, about sixty feet from the point at which they had descended into the system. Crouching at the corner formed by the two earth walls, she looked back into the primary arroyo from which she had come.
On the desert above, one of the surviving assassins shoved the dangling corpse off the brink, into the deep gulch, apparently to see if she was still immediately below them and if she would be tricked into opening fire. When there was no fire, the two survivors became bolder. One lay at the brink with a submachine gun, covering the other man while he slid down. Then the first gunman covered the second’s descent.
When the second man joined the first, Laura stepped boldly around the corner and squeezed off a two-second burst. Both of her pursuers were so startled by her aggressiveness that they did not return fire but threw themselves toward the deep, vertical erosion channels in the arroyo wall, seeking shelter there as she had sheltered while waiting for the opportunity to shoot them off the top of the cliff. Only one of them made it to cover. She blew the other one away.
