The man who'd warned him continued to watch for a reasonable gap in the flood of racing cars. They weren't crowded now as they had been, but it was still impossible to start in low and get back in the stream of vehicles without an almost certain crash. Then he turned his head back, staring at Lockley.
"Hell! Somebody told me to check on her. I was routing men out and loading 'em on whatever came by. I forgot!"
A man in the back of the sedan said, "She hadn't left when we did. I saw her. But I thought she had a ride all set."
The man at the wheel said furiously, "She hasn't passed us! Unless she's in one of these...."
Lockley set his teeth. He watched each oncoming car intently. A girl among these fugitives would have been put with the driver in the cab of a truck, and he'd have seen a woman in any of the private cars.
"If I don't see her go by," he said grimly, "I'll go up to the camp and see if she's still there."
The man in the driver's seat looked relieved.
"If she's left behind, it's her fault. If you hunt for her, make it fast and be plenty careful. Keep to the camp and stay away from the lake. There was a hell of an explosion over there this morning. Three men went to see what'd happened. They didn't come back. Two more went after 'em, and something hit them on the way. They smelled something worse than skunk. Then they were paralyzed, like they had hold of a high-tension line. They saw crazy colors and heard crazy sounds and they couldn't move a finger. Their car ditched. In a while they came out of it and they came back—fast! They'd just got back when we got short wave orders for everybody to get out. If you look for that girl, be careful. If she's still there, you get her out quick!" Then he said sharply, "Here's a chance for us to get going. Move out of the way!"
There was a gap in the now diminishing spate of cars. The driver of the stopped car drove furiously onto the highway. He shifted gears and accelerated at the top of his car's power. Another car behind him braked and barely avoided a crash while blowing its horn furiously. Then the traffic went on. But it was lessening now. It was mostly private cars, owned by the workmen.
Suddenly there were no cars coming down the long straight stretch of road. Lockley got back on the highway and resumed his rush toward the spot the others fled from. He heard behind him the diminishing rumble and roar of the fugitive motors. He jammed his own accelerator down to the floor and plunged on.
There'd been an explosion by the lake, the man who'd warned him said. That checked. Three men went to see what had happened. That was reasonable. They didn't come back. Considering what Vale had reported, it was almost inevitable. Then two other men went to find out what happened to the first three and—that was news! A smell that was worse than skunk. Paralysis in a moving car, which ditched. Remaining paralyzed while seeing crazy colors and hearing crazy sounds.... Lockley could not even guess at an explanation. But the men had remained paralyzed for some time, and then the sensations lifted. They had fled back to the construction camp, evidently fearing that the paralysis might return. Their narrative must have been hair-raising, because when orders had come for the evacuation of the camp, they had been obeyed with a promptitude suggesting panic. But apparently nothing else had happened.
The first three men were still missing—or at least there'd been no mention of their return. They'd either been killed or taken captive, judging by Vale's account and obvious experience. He was either killed or captured, too, but it still seemed strange that Lockley had heard so much of that struggle via a tight beam microwave transmitter that needed to be accurately aimed. Vale had been captured or killed. The three other men missing probably had undergone the same fate. The two others had been made helpless but not murdered or taken prisoner. They'd simply been held until when they were released they'd flee.
The car went over a bridge and rounded a curve. Here a deep cut had been made and the road ran through it. It came out upon undulating ground where many curves were necessary.
Another car came, plunging after the others. In the next ten miles there were, perhaps a dozen more. They'd been hard to start, perhaps, and so left later than the rest. Jill wasn't in any of them. There was one car traveling slowly, making thumping noises. Its driver made the best time he could, following the others.
Sober common sense pointed out that Vale's account was fully verified. There'd been a landing of non-human creatures in a ship from outer space. The killing or capture of the first three men to investigate a gigantic explosion was natural enough—the alien occupants of a space ship would want to study the inhabitants of the world they'd landed on. The mere paralysis and release of two others could be explained on the theory that the creatures who'd come to earth were satisfied with three specimens of the local intelligent race to study. They had Vale, too. They weren't trying to conceal their arrival, though it would have been impossible anyhow. But it was plausible enough that they'd take measures to become informed about the world they'd landed on, and when they considered that they knew enough, they'd take the action they felt was desirable.
All of which was perfectly rational, but there was another possibility. The other possible explanation was—considering everything—more probable. And it seemed to offer even more appalling prospects.
He drove on. Jill Holmes. He'd seen her four times; she was engaged to Vale. It seemed extremely likely that she hadn't left the camp with the workmen. If Lockley hadn't been obsessed with her, he'd have tried to make sure she was left behind before he tried to find her. If she was still at the camp, she was in a dangerous situation.
There'd been no other car from the camp for a long way now. But there came a sharp curve ahead. Lockley drove into it. There was a roar, and a car came from the opposite direction, veering away from the road's edge. It sideswiped the little car Lockley drove. The smaller car bucked violently and spun crazily around. It went crashing into a clump of saplings and came to a stop with a smashed windshield and crumpled fenders, but the motor was still running. Lockley had braked by instinct.
The other car raced away without pausing.
Lockley sat still for a moment, stunned by the suddenness of the mishap. Then he raged. He got out of the car. Because of its small size, he thought he might be able to get it back on the road with saplings for levers. But the job would take hours, and he was irrationally convinced that Jill had been left behind in the construction camp.
He was perhaps five miles from Boulder Lake itself and about the same distance from the camp. It would take less time to go to the camp on foot than to try to get the car on the road. Time was of the essence, and whoever or whatever the occupants of the landed ship might be, they'd know what a road was for. They'd sight an intruder in a car on a road long before they'd detect a man on foot who was not on a highway and was taking some pains to pass unseen.
He started out, unarmed and on foot. He was headed for the near neighborhood of the thing Vale had described as coming from the sky. He was driven by fear for Jill. It seemed to him that his best pace was only a crawl and he desperately needed all the speed he could muster.
He headed directly across country for the camp. All the world seemed unaware that anything out of the ordinary was in progress. Birds sang and insects chirruped and breezes blew and foliage waved languidly. Now and again a rabbit popped out of sight of the moving figure of the man. But there were no sounds, or sights or indications of anything untoward where Lockley moved. He reflected that he was on his way to search for a girl he barely knew, and whom he couldn't be sure needed his help anyway.
