Farrow nodded at me almost imperceptibly. Then she said to Carroll, "Well, we won't keep you. Too bad the Mannheims moved, without leaving an address."

"Yeah," he said with obvious semi-interest. He eyed his half-plowed field and Farrow started her car.

We started off and he turned to go back to his work. "Anything?" I asked.

"No," she said, but it was a very puzzled voice. "Nothing that I can put a finger on."

"But what?"

"I don't know much about real estate deals," she said. "I suppose that one family could move out and another family move in just in this short a time."

"Usually they don't let farmlands lie fallow," I pointed out. "If there's anything off color here, it's the fact that they changed their residence without changing the Highway sign."

"Unless," I suggested brightly, "this is the coincidence. Maybe this sign is really one that got busted."

Farrow turned her car into the main highway and we went along it. I could have been right about the spoke actually being broken instead of removed for its directing purpose. I hoped so. In fact I hoped so hard that I was almost willing to forget the other bits of evidence. But then I had to face the truth because we pa.s.sed another Highway Sign and, of course, its directional information pointed to that farm. The signs on our side of the highway were upside down; indicating that we were leaving the way station. The ones that were posted on the left hand side were rightside up, indicating that the drive was approaching a way station. That cinched it.

#Well,# as I told both Farrow and me, #one error doesn't create a trend.

Let's take another look!#

One thing and another, we would either hit another way station before we got to Homestead, or we wouldn't. Either one could put us wise. So we took off again with determination and finally left that side of erroneous Highway Signs when we turned onto Route 66. We weren't on Route 66 very long because the famous U.S. Highway sort of trends to the Northeast and Homestead was in a Southern portion of Texas. We left Route 66 at Amarillo and picked up U.S. 87, which leads due South.

Not many miles out of Amarillo we came up another set of Highway Signs that pointed us on to the South. I tried to remember whether this section led to Homestead by a long route, but I hadn't paid too much attention to the maps when I'd had the chance and therefore the facts eluded me.

We'd find out, Farrow and I agreed, and then before we could think much more about it, we came upon a way station sign that pointed in to another farmhouse.

"Easy," I said.

"You bet," she replied, pointing to the rural-type mailbox alongside the road.

I nodded. The box was not new but the lettering on the side was. "Still wet," I said with a grunt.

Farrow slowed her car as we approached the house and I leaned out and gave a cheerful hail. A woman came out of the front door and waved at us.

"I'm trying to locate a family named Harrison," I called. "Lived around here somewhere."

The woman looked thoughtful. She was maybe thirty-five or so, clean but not company-dressed. There was a smudge of flour on her cheek and a smile on her face and she looked wholesome and honest.

"Why, I don't really know," she said. "That name sounds familiar, but it is not an uncommon name."

"I know," I said uselessly. Farrow nudged me on the ankle with her toe and then made a swift sign for "P" in the hand-sign code.

"Why don't you come on in?" invited the woman. "We've got an area telephone directory here. Maybe--?"

Farrow nudged me once more and made the sign of "M" with her swift fingers. We had hit it this time; here was a woman perceptive and a Mekstrom residing in a way station. I took a mild dig at her hands and there was no doubt of her.

A man's head appeared in the doorway above the woman; he had a hard face and he was tall and broad shouldered but there was a smile on his face that spread around the pipe he was biting on. He called, "Come on in and take a look."

Farrow made the sign of "T" and "M" and that told me that he was a telepath. She hadn't needed the "M" sign because I'd taken a fast glimpse of his hide as soon as he appeared. Parrying for time and something evidential, I merely said, "No, we'd hate to intrude. We were just asking."

The man said, "Oh, shucks, Mister. Come on in and have a cup of coffee, anyway." His invitation was swift enough to set me on edge.

I turned my perception away from him and took a fast cast at the surrounding territory. There was a mildly dead area along the lead-in road to the left; it curved around in a large arc and the other horn of this horseshoe shape came up behind the house and stopped abruptly just inside of their front door. The density of this area varied, the end in which the house was built was so total that I couldn't penetrate, while the other end that curved around to end by the road tapered off in deadness until it was hard to define the boundary.

If someone were pulling a flanking movement around through that horseshoe to cut off our retreat, it would become evident very soon.

A swift thought went through my mind: #Farrow, they're Mekstroms and he's a telepath and she's a perceptive, and they know we're friendly if they're Highways. If they're connected with Scholar Phelps and his--#

The man repeated, "Come on in. We've some mail to go to Homestead that you can take if you will."

Farrow made no sound. She just seesawed her car with three rapid back-and-forth jerks that sent showers of stones from her spinning wheels. We whined around in a curve that careened the car up on its outside wheels. Then we ironed out and showered the face of the man with stones from the wheels as we took off. The shower of dust and stones blinded him, and kept him from latching onto the tail of the car and climbing in. We left him behind, swearing and rubbing dirt from his eyes.

We whipped past the other end of the horseshoe area just as a jeepster came roaring down out of the thickened part into the region where my perception could make out the important things (Like three burly gents wearing hunting rifles, for instance.) They jounced over the rough ground and onto the lead-in road just behind us; another few seconds of gab with our friends and they'd have been able to cut us off.

"Pour it on, Farrow!"

I knew I was a bit of a cowboy, but Farrow made me look like a tenderfoot. We rocketed down the winding road with our wheels riding up on either side like the course in a toboggan run and Farrow rode that car like a test pilot in a sudden thunderstorm.

I was worried about the hunting rifles, but I need not have been concerned. We were going too fast to make good aim, and their jeepster was not a vehicle known for its smooth riding qualities. They lost one character over a rough bounce and he went tail over scalp into the gra.s.s along the way. He scared me by leaping to his feet, grabbing the rifle and throwing it up to aim. But before he could squeeze off a round we were out of the lead-in road and on the broad highway.

Once on the main road again, Farrow put the car hard down by the nose and we outran them. The jeepster was a workhorse and could have either pulled over the house or climbed the wall and run along the roof, but it was not made for chase.

"That," I said, "seems to be that."

"Something is bad," agreed Farrow.

"Well, I doubt that they'll be able to clean out a place as big as Homestead. So let's take our careful route to Homestead and find out precisely what the devil is cooking."

"Know the route?"

"No, but I know where it is on the map and we can figure it out from--"

"Steve, stop. Take a very careful and delicate view over to the right."

"Digging for what?"

"Another car pacing us along a road on the other side of that field."

I tried and failed. Then I leaned back in the seat and closed my eyes and tried again. On this second try I got a very hazy perception of a large moving ma.s.s that could only have been a car. In the car I received a stronger impression of weapons. It was the latter that cinched it.

I hauled out my roadmap and turned it to Texas. I thumbed the sectional maps of Texas until I located the sub-district through which we were pa.s.sing and then I identified this section of U.S. 87 precisely. There was another road parallel and a half mile to the right, a dirt road according to the map-legend. It intersected our road a few miles ahead.

My next was a thorough covering of the road behind; as I expected another car was pacing us just beyond the range of my perception for anything but a rifle aimed at my hide.

Pacing isn't quite the word, I use it in the sense of their keeping up with us. Fact is that all of us were going about as fast as we could go, with safety of tertiary importance. Anyway, they were pacing us and closing down from that parallel road on the right.

I took a fast and very careful scanning of the landscape to our left but couldn't find anything. I spent some time at it then, but still came up with a blank.

#Turn left at that feeder road a mile ahead,# I thought at Farrow and she nodded.
