grinned. "Neither did we. And we still don't get it. But you can be sure we started a few balls rolling. First, Security checked every man's file again. They missed no one. Even the security officers and guards were rechecked. Then they started a program to find out who on the base had any talent as an artist. Nothing was found. The security chief sent photos of the etched picture and the whole bar mechanism to every security agency in the government, including the FBI, Central Intelligence, and the military. He drew a blank. No one had ever heard of anyone calling himself the Earthman, and the technique wasn't familiar."
The scientist paused long enough to eat a little more, then resumed.
"Meanwhile, we were getting a Viking rocket ready to launch. We checked it from nose to fins. We didn't miss a thing. Then we posted a guard around it, and a guard to watch the guard. We took no chances at all. The project engineer even slept near the rocket where he could keep an eye on it."
"Did anyone climb the tower?" Barby asked.
"There was no tower. A Viking rests on its fins. Anyway, it took off. It climbed ten miles, then went on an erratic course. We couldn't control it. Fortunately it crashed on the Las Vegas Bombing and Gunnery Range, which is a closed military area nearby, so no one was hurt. At first we thought it was just one of those typical accidents that happen during rocket research. Even the best-performing rockets sometimes go haywire. But when we got into the wreckage, we found the steering vanes had been tampered with, in a way that inspection couldn't have disclosed."
"Was there a picture?" Scotty asked.
"Not in or on the rocket. But when we got back to the base after inspecting it, everyone was excited. Someone had sketched a knight in armor with crayon right on the concrete of the launching pad."
Rick said thoughtfully, "Then you can eliminate those who went to inspect the crashed Viking."
"Unfortunately, no. We have no way of telling when the picture was drawn. No one was seen near the launching pad between the time the rocket was fired and the discovery of the sketch on our return from the gunnery range."
"Do you think this sabotage is the work of an enemy agent?" Hartson Brant inquired.
John Gordon shrugged. "Perhaps. Yet we don't really think so. In the first place, an enemy agent would probably not leave a calling card. And second, we're reasonably sure no agent could have gotten past the security check."
There was silence while Scotty and the Brants thought over what Gordon had said. The scientist busied himself with the excellent food, and finally accepted a cup of coffee.
Rick voiced aloud the angles that puzzled him the most. "If not an enemy agent, then why the sabotage at all? Who would have anything to gain but an enemy?"
"If we had the answers, we could find the saboteur," Gordon pointed out. "If we knew why he calls himself 'The Earthman' we might also have a lead. But as it is, we're stumped. It could be anyone on the base, including me."
"Is it you?" Barby asked in a stage whisper.
Gordon looked around, as though to make sure there were no eavesdroppers. "I don't think so," he whispered, "but I'll have to admit I haven't looked since yesterday."
"What do you want the boys to do?" Mrs. Brant asked.
The scientist became serious again. "It's a desperate hope," he admitted, "but there is always a possibility they might turn up something if we plant them as undercover agents. Rick and Scotty not only have good sense, but they're lucky. Maybe they'll be lucky enough to stumble over or sniff out a lead."
"How do we do this?" Rick wanted to know. He was definitely interested in the job. Just the idea of witnessing a big rocket shoot was exciting enough, even without the added attraction of a saboteur to be uncovered.
"You get jobs," Gordon stated. "But you'll have to get them on your own merits, because if I intervened in your behalf that would be a tip-off. Only I and the Chief of Security will know about you."
"Can you trust the Chief of Security?" Barby asked.
Gordon smiled. "A fair question. All I can say is, trust must start somewhere. If Tom Preston is the Earthman, I'll turn in my spaceman's suit and proton disintegrator and resign from the human race."
Rick grinned. "All right. We'll trust the Chief of Security on your say-so. What's the next step?"
"Well, you're not old enough to have much of a work history, so we'll have to exaggerate your ages and the time you've worked. It will be safe enough, so far as being found out is concerned," Gordon said. "Security makes all reference checks, including employment, and Tom Preston will handle your cases personally."
Dismal rubbed against Gordon's leg. The scientist slipped him a scrap of cheese from the salad, then looked guiltily at Mrs. Brant.
"John Gordon! How many times have I told you not to feed Dismal at the table?" she exclaimed in mock anger.
Gordon looked sheepish and hung his head. "I'm sorry. Anyway, boys, I'll advance you funds. You fly to Las Vegas as soon as possible and apply to Lomac for jobs."
"To who? I mean, to whom?"
"Lomac, Rick. The base is run by a contractor, an engineering firm by the name of Logan and Macklin, Lomac for short. They hire all but a handful of scientific personnel, like project directors and their chief assistants, who come from a variety of places, including government agencies, universities under contract to the government, and so on."
"Do we apply in Las Vegas?" Scotty asked.
"Yes. Lomac's recruiting office is there. I'll give you the address. However, the base is some distance away, so you'll need transportation. I suggest a jeep. You can pick one up secondhand after you arrive. I'll give you sufficient funds. Also, prepare to hang around Las Vegas for a while. It will take at least a week to process your papers."
"Are we supposed to know you once we get there?" Rick queried.
"Only casually, because of the Spindrift connection. You know who I am, but you don't know me well because you've never worked on a project of mine. I'll find occasion to talk with you privately as needed."
"Another question," Rick said. "Have there been any more sabotage attempts besides the two you mentioned?"
"No. Those first projects went off in fast order, but the next shoot isn't scheduled for about two weeks."
Scotty asked, "What's the name of this base? You haven't told us."
Gordon looked grim. "I hope the name isn't prophetic," he said. "The base was named for the dry lake where the rocket pads are located: Scarlet Lake."
CHAPTER III
Las Vegas, Nevada
Rick and Scotty picked up their luggage at the baggage counter, then paused to survey their surroundings. McCarran Field, the airport for Las Vegas, Nevada, was modern and attractive. But there was no mistaking that this was desert country. Beyond the airport they saw the barren mountains of the Charleston Range, and behind the motels clustered around the airport, they saw flat desert, thinly populated with mesquite and creosote brush.
"Welcome to the wild West," Rick said with a grin.
"Not a cowboy in sight," Scotty commented. "Plenty of dudes, though." He gestured at a group dressed in loud sports clothes. "What now?"
"Let's take a taxi into town, register at the hotel, and then go to Lomac."
"Okay." Scotty hailed a cab from the front of the taxi line. They loaded their baggage and climbed in.
"El Cortez," Rick directed. John Gordon had suggested that hotel, since it was close to Lomac's office in downtown Las Vegas, and the food was good and not expensive.
The taxi rolled through the gateway of McCarran Field and turned toward town. In a few moments they began to pass the fabulous resort hotels on the famous "Strip."
"Wow!" Scotty exclaimed. "Some bunch of fancy shanties!"
The taxi left The Strip, traversed the long lines of motels on Fifth Street, and emerged on Fremont a block from the Cortez. A few minutes
