The Scarlet Lake Mystery: A Rick Brant Science-Adventure Story

by Harold L. Goodwin

  CHAPTER VII

  Careless Mesa

  The boys climbed in the jeep early the following morning.

  Scotty shifted into gear and drove through the base. "The time is nowzero minus twenty-two hours."

  Rick looked at him. "What does that mean?"

  "Firing time for Orion is tomorrow morning, twenty-two hours from now.That must be the reason for the balloon that we just saw go up. Theweather group is starting to watch winds and visibility. Something elseI picked up at maintenance, too. There's going to be a dry run today."

  "Spell it out," Rick requested.

  "As I get it, all hands go through the same procedures they'll followtomorrow morning. The Orion group will fire a small weather rocket tocheck the circuits, and to allow the tracking and monitoring group tocheck their equipment. And do you know what that means?"

  Rick saw it at once. "Mac and Pancho will be going to Careless Mesa!"

  "Yep. But the dry run doesn't start until ten this morning. That givesus plenty of time to get there, look around, and shove off before Macand Pancho show up."

  "Suppose they get there early?" Rick asked.

  "They probably will. We won't hang around, though. According to thecontrol board in the vehicle shop their truck isn't supposed to be readyuntil eight, which is an hour and a half from now."

  Rick thought that was cutting it fine, but he made no further comment.

  Both boys had checked the map again, and knew the route to follow.Scotty drove through the base and onto the access road that led to thefiring areas. In a short time they had a clear view of Orion waiting onits pad, project personnel swarming over the gantry crane as theyperformed a variety of last-day chores. The sight filled Rick withexcitement. To-morrow he would see the big rocket go up.

  "Pretty," Scotty said.

  Rick nodded. Orion was a beautiful sight. Its lines were clean, and itspaint job was colorful, mixing white with high-visibility colors toallow greater ease of visual tracking.

  "Blockhouse ahead," Scotty pointed out.

  It was the first time either of them had seen the blockhouse, thecontrol point from which the rockets were fired. It was within a mile ofthe concrete firing pads, close enough to be in great danger from wildrockets that had gone out of control. For that reason it was made ofheavily reinforced concrete, several feet thick. It could take a directhit from even the biggest rockets without harm to the personnel inside.

  Then the firing area was passed and the jeep sped along next to themiles-long black, oiled path of the airstrip. Soon the strip was behind,then the level floor of the dry lake bed became rough terrain and thejeep began to climb toward the foothills.

  "Isn't there a guard post this way?" Rick asked.

  "Should be."

  There was, a few miles beyond, as the jeep mounted the foothills andwent through a pass. The guard inspected their badges, then waved themon. They were outside of the base area now.

  The dirt road led them across a valley and up a gradual slope to anotherpass through the mountains. This time, as they emerged, Rick pointed toa flat-topped mountain directly ahead. "That's a mesa," he declared."Suppose it's the right one?"

  Scotty squinted against the glare. "Probably. I don't see any others onthe horizon."

  "What are we going to do when we get there?" Rick asked.

  Scotty waved a hand. "Look, and hope there's something to see."

  "Okay. Let it go. We'll wait and see." Rick fell silent, watching thedesert. It was odd, he thought, that most people thought of deserts interms of sand. It was a fact that some deserts were sandy, but this onewas composed of hard-packed earth and stones in which plants struggledfor survival. It was more like smooth clay. Then, as the desert rosefrom smooth plain to mountains, the ground became simply broken rock,sparsely dotted with creosote bush and cholla.

  Once or twice he turned and looked back at the road over which they hadcome. The jeep left a trail of dust behind it, but he could see no dustfrom any other vehicle. Apparently they were well ahead of Big Mac andPancho. He hoped they would stay ahead.

  "If Mac and Pancho do catch up," he said thoughtfully, "we can alwayssay we just came out for the ride, to see a little of the country."

  Scotty gave him a sideways glance. "Think they'd buy it?"

  "Could be. They have no reason to suspect us. We're just a couple ofkids who work on the base."

  The road was steep now, and Scotty shifted into second to take some ofthe strain off the engine.

  Careless Mesa loomed ahead. Rick wondered if the road led all the way tothe top. Apparently it did, because the trail twisted and turned,climbing constantly. He closed his eyes and visualized the map.Somewhere up there the road split.

  Suddenly Scotty pointed. "Look!"

  In a shady spot just off the road two sidewinders were coiled on a rock,beady eyes watching the jeep's passage. The snakes were the color ofmottled sand, the "horns" on their diamond-shaped heads clearlyidentifiable. Their tails were a blur, and he knew they were rattling awarning, but the distinctive buzz couldn't be heard above the jeep'sengine noise.

  Rick restrained a shudder. Although he had no particular fear of snakes,he had an inborn dislike of the creatures. He had read that thesidewinder, or "horned" rattlesnake, was common in the Western deserts.

  Then the jeep rounded a turn with a sheer drop of several hundred feeton Rick's side, and the sidewinders were lost to view. Rick looked downat the steep slope and said, "Nice place to meet a car coming down."

  "Let's not meet one," Scotty replied. He had to drop back into firstgear now, because the climb was very steep.

  The road cut through a notch and emerged onto a relatively level area.Rick tried to get his bearings. The road had twisted and turned so muchhe had lost his sense of direction. The sun's position helped him to getoriented again, and he realized they were high on the side of CarelessMesa, overlooking the road across which they had just traveled.

  "Clearing ahead," Scotty said. "Bet we've reached the station."

  He was right. The road led across a wide shelf, perhaps fifty feet belowthe top of the mesa. On the far side of the shelf the road dipped again.Scotty let the jeep roll to the edge of the dip and they looked down theroadway which twisted and turned and finally forked a thousand feetbelow.

  Scotty put the jeep in reverse and backed to the center of the shelf. Itwas about two hundred feet wide, the road hugging the inner cliff.Toward the edge of the shelf the ground was disturbed by vehicle tracks.

  "Stop here," Rick said.

  Scotty killed the engine, and pointed to a pile of cans near the remainsof a fire. "This must be where Mac and Pancho set up their radar gear."

  Rick looked around him appreciatively. In the direction of Scarlet Lakethere was a clear view for miles. Only the low ridges of interveninghills prevented them from seeing the base itself. A radar outfit couldtrack the rockets from here with no interference at all, once the rockethad risen above the range of low hills.

  Scotty indicated the scenery with a wave of his hand. "Plenty to see.But twenty tons of transistors could be in plain sight and we'd neverknow it. How would you hide stolen goods, if you had to do it?"

  Rick turned and surveyed the base of the cliff that led to the top ofthe mesa. "I'd probably hunt for a space between two big rocks, pack itin, and load rocks on top."

  "And that ain't stuff and nonsense," Scotty agreed. "Come on. Let'sstart moving boulders."

  Rick shook his head as his eyes encompassed the more than a hundredyards of strewn rocks at the cliff's bottom. "Shall we move them a tonat a time?"

  Scotty grinned helplessly. "At that rate we'd be here six months." Hekicked an empty beer can. "Maybe we'd better look in the cans instead."

  As though by magic the can flew into the air, flashing in the sunlight.At the same instant they heard the spiteful crack of a rifle.

  Scotty reacted instantly, and Rick was only a fraction of a secondbehind. They dashed across the road and dove for cover in the rocksbehin
d the jeep.

  The rifle cracked again. A slug whined into space a few feet from theirnoses, leaving a silvery streak of lead on a rock.

  The boys moved again, closer into the face of the cliff, and tookshelter under a slight overhang.

  "Now what?" Rick asked.

  Scotty surveyed the situation, estimated the line of fire from the leadsmear on the rock, then shook his head.

  "We can't get in the jeep and make a run for it, because we'd be rightin the line of fire. He's on top of the mesa, whoever he is. He can'treach us here, but he can reach us if we move, or if he moves."

  The rifle punctuated Scotty's estimate of the situation. This time theslug slapped rock close enough to spatter sandstone chips in theirfaces.

  "We can't stay here," Scotty said grimly. "I'm going to see what I cando."

  "How?" Rick demanded.

  Scotty was busily picking up stone fragments, choosing them by weightand shape. "I can move along the face of the cliff, staying under cover.At least I think I can. If I reach the place where the road drops, I canget up to the top. With luck, I won't be seen. Besides, you can distracthim."

  "How?"

  "I don't know. Put the Brant brain to work and figure out something."Scotty unrolled his sling, slipped the loop over his index finger, andgave Rick a tight grin. "Keep the boy busy, chum. Here I go."

  Scotty moved rapidly but silently, across the bottom of the cliff,taking advantage of every overhanging rock. When Scotty was perhaps tenyards away, Rick moved into action. He picked up a rock, hefted it, thenthrew it into the pile of cans. They scattered noisily, bringing a rifleshot in reply.

  Rick thought swiftly, then peeled off his shirt and wrapped it in agood-sized rock. He gauged the distance and heaved it in the directionopposite the one Scotty had taken, aiming for a niche under an overhangsix yards away. He hoped the motion would be mistaken for one of them.Evidently he succeeded, because a rifle slug chipped rock a foot awayfrom the shirt as it rolled under the overhang.

  Raising his head cautiously, he saw a rock perched precariously on thesteep slopes. Evidently it had come to rest there, or the rains hadwashed away much of its support. He found a rock to throw, sighted withcare, and tossed it underhand. It struck directly under the balancedrock and dug away enough dirt to upset its equilibrium. The rock tumbleddown, bringing a tiny landslide of other rocks and dirt with it. Therewas no response from the rifle this time.

  Rick turned to see how Scotty was doing, but his pal was out of sight,behind some boulder along the way. Now what? His bag of tricks wasalmost exhausted.

  He looked outward, across the road. A few yards to the right of thecampfire and cache of cans was a rock pile. It was big enough to shieldhim, if he could make it. He took a deep breath. If he dodged andtwisted fast enough, the rifleman probably couldn't hit him, and hewould certainly have the man's full attention. That would give Scotty abetter chance.

  He chose a rock, hefted it, and got up into a sprinting position. Hemade sure of his footing, then simultaneously tossed the rock sidewaysto attract the rifleman's eye, and charged out of the niche.

  Ten feet and he jumped sideways, took two forward leaps, and wentsideways again. The rifle barked and dirt spurted where he had justbeen. But by then Rick was within reach of the rock pile, and he wentover it in a headlong dive, rolling like a tumbler as he landed. Quicklyhe flattened out, as close to the rocks as he could get. A bullet whinedoff the top of the pile, and then there was silence.

  Rick's heart pounded and his breath came in gasps. He had made it! Buthow about Scotty? He risked a push-up that brought his head to the levelof the upper rocks in time to see Scotty fire his first sling stone. Hispal had reached a position just below the top of the mesa, where hisstones would clear the top without exposing him. As Rick watched, Scottyput another stone in the pouch and let fly. The stone smashed into rockon top of the mesa. A third stone, and Rick suddenly caught a glimpse ofmotion on the mesa top, directly above him. The rifleman was changingposition! Evidently Scotty's stones were coming too close!

  "Watch it!" he yelled. "Watch out, Scotty! He's moving!"

  Three closely spaced shots sent Scotty to the ground as slugs whined offthe mesa rim directly above him. Then there was silence. Rick heard, asthough from far off, the clatter of rock. He waited. Scotty was waiting,too.

  _A bullet whined off the top of the rock pile, and thenthere was silence_]

  Minutes ticked by. Then, faintly, Rick heard a sound that could onlyhave been a horse whinnying.

  Scotty stood upright and climbed to the very top of the mesa. Rickstarted to yell, then choked it back. Scotty must know what he wasdoing. He saw his pal walk leisurely out of sight. Rick stood up,watching. In a moment Scotty reappeared, climbing down the incline hehad used to get to the top. In a moment the boys were face to face.

  "He's gone," Scotty announced. "Had a horse staked out below theopposite side of the mesa. I saw him ride off. He was too far away forme to get a good look at him."

  "Mighty strange," Rick said with a sigh of relief.

  Scotty nodded. "Strange is right. You know what? He saw me standingthere on the rim. He turned and looked at me, and he waved."

  "Waved?" Rick asked.

  "Yep. It was a real jaunty wave."

  Rick shook his head in bewilderment. "My, that was friendly."

  "I thought so," Scotty agreed. "Come on, boy. We've got to make tracksout of here. Time is running out."

  Rick collected his shirt and jumped into the jeep. Scotty backed aroundand headed toward the base as fast as the road allowed. Not until theywere down on relatively level ground did they try to converse.

  "The rifleman must have read about David and Goliath," Rick said. "Whyelse would he run off?"

  Scotty chuckled. "He was helpless. He was in deadly peril, as thestorybooks say. Seriously, I think he _was_ helpless."

  Rick stared at his pal. Scotty could mean only one thing. "Then he hadno intention of hitting us?"

  "I doubt it. He was shooting at short range, and even a poor shotcouldn't very well have missed as often as he did. Besides, I don'tthink you'd find many poor shots with rifles in this country."

  "Then he must have been trying to scare us off," Rick said thoughtfully."When you started heaving rocks at him, he knew we weren't scaring verymuch."

  "Not much," Scotty said ruefully. "I don't know about you, but myinnards turned to custard."

  Rick grinned. He knew exactly what Scotty meant. "If things had happeneda little more slowly, I'd have dropped dead from sheer fright. But Ididn't have time. Anyway, when you started with your sling, he had achoice of shooting for keeps or getting out of there. So he got. Is thathow you figure it?"

  "Exactly right. What other explanation is there? Stones against rifleslugs isn't much of a contest. I only tried it because there wasn'tanything else to do."

  "We could have stayed under cover until Mac and Pancho arrived," Rickpointed out.

  "Negative. All he had to do was shift position and he'd have had a clearshot at us."

  That was true, Rick realized. "But why did he try to scare us off?"

  "It beats me. He wasn't a guard, I'm sure. If he was guarding something,he wouldn't have ridden off and left us there. And there wasn't anythingpersonal in it, because he waved at me like an old pal. It was a kindof humorous wave. You know? Real jaunty."

  Rick asked the obvious question. "Was it the Earthman?"

  And Scotty made the obvious answer. "I didn't have a chance to ask him.Anyway, he didn't wear armor."

  Rick had been keeping his eye on the road ahead. "Pull over," he saidquickly. "Let's get out and be looking at cactus or something. I thinkMac and Pancho are coming."

  Scotty complied quickly and shut off the jeep engine. The boys got outand walked quickly into the desert, found a barrel cactus, and begandissecting it with Rick's scout knife.

  The dust cloud that marked an oncoming vehicle grew larger, and in a fewminutes they saw the panel truck and the trailer w
ith radar dish mountedon it. As the truck drew nearer they stood up, Rick holding the cactusimpaled on his knife. It was a natural action; simple curiosity wouldrequire that they pause to see who might be in a passing vehicle.

  The truck drew abreast and slowed. Big Mac was driving. Pancho leanedout and waved. "Hiya, kids!"

  They echoed him. "Hiya, Pancho." Then the truck was past, en route tothe mesa for the day's dry run.

  Rick drew a deep breath. "In the clear," he said with relief. Suddenlyhe grinned. "This is what I call progress. We go to Careless Mesa. Wefind nothing. We get shot at. We add to the mystery without adding asingle thing to the puzzle. One more day like this and we'll have to putour Junior G-man badges back in the cereal box where we got 'em."

  "I beat you," Scotty said unhappily. "I left mine under a rock at thetop of the mesa."
