The Blue Ghost Mystery Part 20

Rick had to laugh, too. "Now what do we do?"

"Look in the upland cornfield."

They started the survey of the cornfield directly above the mine entrance, where they had first seen the three ghosts. Tracks were visible almost at once.

"We're lucky," Scotty said. "Even with the weeds between the rows there's enough bare ground so we can do some real tracking. Let's see how the tracks run."

As Scotty had predicted, the tracking was much easier. A few yards into the cornfield they came to a gap where a few seeds had failed to germinate or the plants had died. It was a bare s.p.a.ce, spa.r.s.ely grown with weeds.

Scotty pointed to the three sets of tracks, and put his own feet in one set, while Rick did the same with another set. From the position of the third set it was clear that the three men had faced each other.

Rick said excitedly, "They paused and bent over. But over what?"

They scrutinized the ground minutely. It seemed normal enough. There was absolutely no sign that the earth had been disturbed.

Rick picked up a handful of soil and examined it. "Dirt," he said.

"Plain dirt. Why was it so interesting to the spooks?"

"Try your lens," Scotty reminded him.

Rick did so. The lens showed the usual combination of mineral and organic matter of various sizes and colors. "I can't see anything unusual," he reported. "Maybe the lens isn't powerful enough. I'll take a sample and look at it under the microscope later." He found a sc.r.a.p of paper in his wallet and folded a bit of dirt into it.

"Let's continue," Scotty urged.

They worked their way across the cornfield, following the tracks. Twice more they found places where the ghosts had paused to confer about something, or examine something.

Then, at the edge of the cornfield, they lost the tracks in a rank growth of weeds. Probably the ghosts had trampled the weeds last night, but they had sprung up again and left no trace of the pa.s.sage.

Scotty took the lead. "I'll show you where the car was parked."

They traveled through alternate weeds and hay to where the hilltop dropped away rapidly to a valley about three hundred feet below. This marked the end of the igneous outcropping in which the lead mine was located, Rick guessed. The hill was steep, and overgrown with blackberry bushes.

"I got caught a thousand times in as many feet last night," Scotty commented. "It's easy by day, but don't try it by night." He led the way through clear s.p.a.ces between the th.o.r.n.y patches, always going downhill.

It wasn't long before Rick saw the road, if it could be called that. It was two ruts with gra.s.s growing between them.

"Doesn't look like U.S. Highway Number 66," he remarked.

"There's a man who thinks it is," Scotty replied.

Rick looked to where his pal pointed. The Frostola man was approaching on his scooter. The sound of the little motor was just audible, and Rick's first impulse was to duck, but Scotty said, "Too late. He saw us just as we saw him. Let's walk down to the road and make it casual."

They did so, and the peddler approached, b.u.mping over the uneven surface.

"Howdy," he greeted them. "Where does this road go?"

"We don't know," Scotty replied.

Rick added, "We're strangers in the area."

"I'm pretty new myself," the man said cheerfully. "Saw this road and thought there might be a settlement where I could find some new customers."

"We don't know of any," Rick said.

"Looks like I might as well go back to town, then. Want a lift? You can hang onto the step behind me."

"No, thanks," Scotty replied. "We're staying just over the hill."

The Frostola man turned his scooter wagon, gave them a wave, and went on his way back toward town. The boys watched until he drove out of sight.

"There's an optimist," Scotty said. "Follows a pair of ruts, hoping to find civilization at the other end."

Rick grinned. "He certainly likes this part of Virginia. There's one thing about peddling Frostola here--"

"What's that?"

"No customers to bother you. It's easy to commune with Nature."

"Aye-aye. Does he look like a nature lover to you?"

"Now that you mention it, I've seen people who fitted the part better.

We scared him away, that's for sure. But what was he doing here?"

Scotty considered. "If he wanted to reach the mine area without people noticing him, he could park his scooter here and walk over the hill."

"He could," Rick agreed. "But why would he want to reach the mine area?"

"Not to sell Frostola. That's for sure."

"Uh-uh. My guess is he has to reset the Blue Ghost."

"Reset it?"

"Sure. Think about it. The projector can't go on operating forever when a clock reaches nine, can it? It must need servicing and resetting."

"And loading with methyl chloride to squirt at us?"

"Too true." Rick had wondered about that. "But how does the chemical squirter work? Where is it? The projector must be close to the Blue Ghost, if the chemical came from the same place."

Scotty laughed. "You don't discourage easily, do you? We tried to find a projector beam the other night, remember? What did we get for it? A squirt in the face. No projector, no nothing."

"There has to be a projector, or an imagemaker of some kind," Rick insisted, "unless you're admitting the ghost is real."

"Where would it be located?"

"Very close, I'd guess. Hidden somewhere near the spring pool, batteries and all. It has to be, and I think we'd better spend some time looking."

"Starting where? Don't tell me--it has to be the mine."
