Nurse Gloria Farrow waved at me from the ramp of the jetliner, and I ran forward to collect her baggage. She eyed me curiously but said no more than the usual greetings and indication of which bag was hers.

I knew that she was reading my mind like a psychologist all the time, and I let her know that I wanted her to. I let my mind merely ramble on with the usual pile of irrelevancies that the mind uses to fill in blank spaces. It came up with a couple of notions here and there but nothing definite. Miss Farrow followed me to my car without saying a word, and let me install her luggage in the trunk.

Then, for the first time, she spoke: "Steve Cornell, you're as healthy as I am."

"I admit it."

"Then what is this all about? You don't need a nurse!"

"I need a competent witness, Miss Farrow."

"For what?" She looked puzzled. "Suppose you stay right here and start explaining."

"You'll listen to the bitter end?"

"I've two hours before the next plane goes back. You'll have that time to convince me—or else. Okay?"

"That's a deal." I fumbled around for a beginning, and then I decided to start right at the beginning, whether it sounded cockeyed or not.

Giving information to a telepath is the easiest thing in the world. While I started at the beginning, I fumbled and finally ended up by going back and forth in a haphazard manner, but Miss Farrow managed to insert the trivia in the right chronological order so that when I finished, she nodded with interest.

I posed the question: #Am I nuts?#

"No, Steve," she replied solemnly. "I don't think so. You've managed to accept data which is obviously mingled truth and falsehood, and you've managed to question the validity of all of it."

I grunted. "How about the crazy man who questions his own sanity, using this personal question as proof of his sanity since real nuts know they're sane?"

"No nut can think that deep into complication. What I mean is that they cannot even question their own sanity in the first premise of postulated argument. But forget that, what I wanted to know is where you intend to go from here."

I shook my head unhappily. "When I called you I had it all laid out like a roadmap. I was going to show you proof and use you as an impartial observer to convince someone else. Then we'd go to the Medical Center and hand it to them on a platter. Since then I've had a shock that I can't get over, or plan beyond. Scholar Phelps is a Mekstrom. That means that the guy knows what gives with Mekstrom's Disease and yet he is running an outfit that professes to be helpless in the face of this disease. For all we know Phelps may be the head of the Highways in Hiding, an organization strictly for profit of some sort at the expense of the public welfare."

"You're certain that Phelps is a Mekstrom?"

"Not absolutely positive. I had to close my mind because there might be a telepath on tap. But I can tell you that nobody with normal flesh-type fingers ever made that solid rap."

"A fingernail?"

I shook my head at her. "That's a click. With an ear at all you'd note the difference."

"I'll accept it for the moment. But lacking your original plan, what are you going to do now?"

"I'm not sure beyond showing you the facts. Maybe I should call up that F.B.I. team that called on me after Thorndyke's disappearance and put it in their laps."

"Good idea. But why would Scholar Phelps be lying? And beyond your basic suspicions, what can you prove?"

"Very little. I admit that my evidence is extremely thin. I saw Phillip Harrison turning head bolts on a tractor engine with a small end wrench. It should require a crossbar socket and a lot of muscle. Next is the girl in Ohio who should be a bloody mess from the way she was treated. Instead she got up and tried to chase me. Then answer me a puzzler: Did the Harrisons move because Marian caught Mekstrom's, or did they move because they felt that I was too close to discovering their secret? The Highway was relocated after that, you'll recall."

"It sounds frightfully complicated, Steve."

"You bet it does," I grunted. "So next I meet a guy who is supposed to know all the answers; a man dedicated to the public welfare, medicine, and the ideal of Service. A man sworn to the Hippocratic Oath. Or," I went on bitterly, "is it the Hypocritic Oath?"

"Steve, please—"

"Please, Hell!" I stormed. "Why is he quietly sitting there in Mekstrom hide while he is overtly grieving over the painful death of his fellow man?"

"I wouldn't know."

"Well, I'm tired of being pushed around," I growled.

"Pushed around?" she asked quietly.

With a trace of scorn, I said, "Miss Farrow, I can see two possible answers. Either I am being pushed around for some deliberate reason, or I'm too smart, too cagey and too dangerous for them to handle directly. It takes only about eight weeks for me to reluctantly abandon the second in favor of the first."

"But what makes you think you are being pushed?" she wanted to know.

"You can't tell me that I am so important that they couldn't erase me as easily as they did Catherine and Dr. Thorndyke. And now that his name comes up, let's ask why any doctor who once met a casual patient would go to the bother of sending a postcard with a message on it that is certain to cause me unhappiness. He's also the guy who nudged me by calling my attention to my so-called 'shock hallucination' about Father Harrison lifting my car while Phillip Harrison raced into the fire to make the rescue. Add it up," I told her sharply. "Next he is invited to Medical Center to study Mekstrom's. Only instead of landing there, he sends me a postcard with one of the Highways in the picture, after which he disappears."

Miss Farrow nodded thoughtfully. "It is all tied up with your Highways and your Mekstrom People."

"That isn't all," I said. "How come the Harrisons moved so abruptly?"

"You're posing questions that I can't answer," complained Miss Farrow. "And I'm not one hundred percent convinced that you are right."

"You are here, and if you take a look at what I'll show you, you'll be convinced. We'll put it this way, to start: Something cockeyed is going on. Now, one more thing I can add, and this is the part that confuses me: Everything that has been done seems to point to me. So far as I can see they are operating just as though they want me to start a big hassle that will end up by getting the Highways out of their Hiding."

"Why on earth would they be doing that?" she wanted to know.

"I don't have the foggiest notion. But I do have that feeling and there is evidence pointing that way. They've let me in on things that normally they'd be able to conceal from a highly trained telepath. So I intend to go along with them, because somewhere at the bottom of it all we'll find the answer."

She nodded agreement.

Now I started up the car, saying, "I'm going to find us one of the Highways in Hiding, and we'll follow it to one of the way stations. Then you'll see for yourself that there is something definitely fishy going on."

"This I'd like to see," she replied quietly. Almost too quietly. I took a dig at her as I turned the car out through a tight corner of the lot onto the road. She was sitting there with a noncommittal expression on her face and I wondered why. She replied to my thought: "Steve, you must face one thing. Anything you firmly believe will necessarily pass across your mind as fact. So forgive me if I hold a few small doubts until I have a chance to survey some of the evidence at first hand."

"Sure," I told her. "The first bit won't be hard."

I drove eagerly across Illinois into Iowa watching for road signs. I knew that once I convinced someone else, it would be easier to convince a third, and a fourth, and a fiftieth until the entire world was out on the warpath. We drove all day, stopping for chow now and then, behaving like a couple out on a vacation tour. We stopped in a small town along about midnight and found a hotel without having come upon any of the hidden highways.

We met at breakfast, talked our ideas over mildly, and took off again. We crossed into Nebraska about noon and continued to meander until late in the afternoon when we came upon our first giveaway road sign.

"There," I told her triumphantly.

She nodded. "I see the sign, Steve. That much I knew. Now all you have to do is to show me the trial-blazes up in that emblem."

"Unless they've changed their method," I told her, "this one leads West, slightly south of." I stopped the car not many yards from the sign and went over it with my sense of perception. #You'll note the ease with which the emblem could be turned upside down,# I interjected. #Note the similar width of the top and bottom trefoil, so that only a trained and interested observer can tell the difference.#

I drove along until we saw one on the other side of the road and we stopped again, giving the sign a thorough going over. #Note that the signs leading away from the direction are upside down,# I went on. I didn't say a word, I was using every ounce of energy in running my perception over the sign and commenting on its various odds and ends.

#Now,# I finished, #we'll drive along this Highway in Hiding until we come to some intersection or hideout. Then you'll be convinced.#

She was silent.

We took off along that road rather fast and we followed it for miles, passing sign after sign with its emblem turned up along the right side of the road and turned upside-down when the sign was on the left.

Eventually we came to a crossing highway, and at that I pointed triumphantly. "Note the missing spoke!" I said with considerable enthusiasm. "Now, Miss Farrow, we shall first turn against it for a few miles and then we shall U-turn and come back along the cross highway with it."

"I'm beginning to be convinced, Steve."

We turned North against the sign and went forty or fifty miles, just to be sure. The signs were all against us. Eventually I turned into a gas station and filled the carte up to the scuppers. As we turned back South, I asked her, "Any more comment?"

She shook her head. "Not yet."

I nodded. "If you want, we'll take a jaunt along our original course."

"By all means."

"In other words you are more than willing to be convinced?"

"Yes," she said simply. She went silent then and I wondered what she was thinking about, but she didn't bother to tell me.

Eventually we came back to the crossroad, and with a feeling of having been successful, I continued South with a confidence that I had not felt before. We stopped for dinner in a small town, ate hastily but well, and then had a very mild debate.

"Shall we have a drink and relax for a moment?"

"I'd like it," she replied honestly. "But somehow I doubt that I could relax."

"I know. But it does seem like a good idea to take it easy for a half hour. It might even be better if we stopped over and took off again in the morning."

"Steve," she told me, "the only way I could relax or go to sleep would be to take on a roaring load so that I'd pass out cold. I'd rather not because I'd get up tomorrow with a most colossal hangover. Frankly, I'm excited and I'd prefer to follow this thing to a finish."

"It's a deal," I said. "We'll go until we have to stop."

It was about eight o'clock when we hit the road again.

---

By nine-forty-five we'd covered something better than two hundred miles, followed another intersection turn according to the missing spoke, and were heading well toward the upper right-hand corner of Colorado on the road map.

At ten o'clock plus a few minutes we came upon the roadsign that pointed the way to a ranch-type house set prettily on the top of a small knoll several hundred yards back from the main road. I stopped briefly a few hundred feet from the lead-in road and asked Miss Farrow:

"What's your telepath range? You've never told me."

She replied instantly, "Intense concentration directed at me is about a half mile. Superficial thinking that might include me or my personality as a by-thought about five hundred yards. To pick up a thought that has nothing to do with me or my interests, not much more than a couple of hundred feet. Things that are definitely none of my business close down to forty or fifty feet."

That was about the average for a person with a bit of psi training either in telepathy or in esper; it matched mine fairly well, excepting that part about things that were none of my business. She meant thoughts and not things. I had always had a hard time differentiating between things that were none of my damned business, although I do find it more difficult to dig the contents of a letter between two unknown parties at a given distance than it is to dig a letter written or addressed to a person I know. Things are, by and large, a lot less personal than thoughts, if I'm saying anything new.

"Well," I told her, "this is it. We're going to go in close enough for you to take a 'pathic look-around. Keep your mind sensitive. If you dig any danger, yell out. I'm going to extend my esper as far as I can and if I suddenly take off like a startled spacecraft, it's because I have uncovered something disagreeable. But keep your mind on them and not me, because I'm relying on you to keep posted on their mental angle."

Miss Farrow nodded. "It's hard to remember that other people haven't the ability to make contact mentally. It's like a normal man talking to a blind man and referring constantly to visible things because he doesn't understand. I'll try to remember."

"I'm going to back in," I said. "Then if trouble turns up, I'll have an advantage. As soon as they feel our minds coming in at them, they'll know that we're not in there for their health. So here we go!"

"I'm a good actor," she said. "No matter what I say, I'm with you all the way!"

I yanked the car forward, and angled back. I hit the road easily and started backing along the driveway at a rather fast speed with my eyes half-closed to give my esper sense the full benefit of my concentration along the road. When I was not concentrating on how I was going to turn the wheel at the next curve I thought, #I hope these folks know the best way to get to Colorado Springs from here. Dammit, we're lost!#

Miss Farrow squeezed my arm gently, letting me know that she was thinking the same general thoughts.

Suddenly she said, "It's a dead area, Steve."

It was a dead area, all right. My perception came to a barrier that made it fade from full perception to not being able to perceive anything in a matter of yards. It always gives me an eerie feeling when I approach a dead area and find that I can see a building clearly and not be able to cast my perception beyond a few feet.

I kept on backing up into the fringe of that dead area until I was deep within the edge and it took all my concentration to perceive the road a few feet ahead of my rear wheels so that I could steer. I was inching now, coming back like a blind man feeling his way. We were within about forty feet of the ranch house when Miss Farrow yelped:

"They're surrounding us, Steve!"

My hands whipped into action and my heavy right foot came down on the gas-pedal. The car shuddered, howled like a wounded banshee, and then leaped forward with a roar.

A man sprang out of the bushes and stood in front of the car like a statue with his hand held up. Miss Farrow screamed something unintelligible and clutched at my arm frantically. I threw her hand off with a snarl, kept my foot rammed down hard and hit the man dead center. The car bucked and I heard metal crumple angrily. We lurched, bounced viciously twice as my wheels passed over his floundering body, and then we were racing like complete idiots along a road that should not have been covered at more than twenty. The main road came into sight and I sliced the car around with a screech of the rear tires, controlled the deliberate skid with some fancy wheel-work and some fast digging of the surrounding dangers.

Then we were tearing along the broad and beautifully clear concrete with the speedometer needle running into the one-fifteen region.

"Steve," said Miss Farrow breathlessly, "That man you hit—"

In a hard voice I said, "He was getting to his feet when I drove out of range."

"I know," she said in a whimper. "I was in his mind. He was not hurt! God! Steve—what are we up against?" Her voice rose to a wail.

"I don't know, exactly," I said. "But I know what we're going to do."

"But Steve—what can we do?"

"Alone or together, very little. But we can bring one person more out along these Highways and then convince a fourth and a fifth and a fiftieth and a thousandth. By then we'll be shoved back off the stage while the big wheels grind painfully slow but exceedingly meticulous."

"That'll take time."

"Certainly. But we've got a start. Look how long it took getting a start in the first place."

"But what is their purpose?" she asked.

"That I can't say. I can't say a lot of things, like how, and why and wherefore. But I know that now we have a front tooth in this affair we're not going to let go." I thought for a moment. "I could use Thorndyke; he'd be the next guy to convince if we could find him. Or maybe Catherine, if we could find her. The next best thing is to get hold of that F.B.I. Team that called on me. There's a pair of cold-blooded characters that seem willing to sift through a million tons of ash to find one valuable cinder. They'll listen. I—"

Miss Farrow looked at her watch; I dug it as she made the gesture. #Eleven o'clock.#

"Going to call?" she asked.

"No," I said. "It's too late. It's one in New York now and the F.B.I. Team wouldn't be ready for a fast job at this hour."

"So?"

"I have no intention of placing a 'When you are ready' call to a number identified with the Federal Bureau of Investigation. Not when a full eight hours must elapse between the call and a reply. Too much can happen to us in the meantime. But if I call in the morning, we can probably take care of ourselves well enough until they arrive if we stay in some place that is positively teeming with citizens. Sensible?"

"Sounds reasonable, Steve."

I let the matter drop at that; I put the go-pedal down to the floor and fractured a lot of speed laws until we came to Denver.

We made Denver just before midnight and drove around until we located a hotel that filled our needs. It was large, which would prevent overt operations on the part of the 'enemy' and it was a dead area, which would prevent one of them from reading our minds while we slept, and so enable them to lay counterplans against us.

The bellhop gave us a knowing leer as we registered separately, but I was content to let him think what he wanted. Better that he get the wrong idea about us than the right one. He fiddled around in Miss Farrow's room on the ninth, bucking for a big tip—not for good service, but for leaving us alone, which he did by demonstrating how big a nuisance he could be if not properly rewarded. But finally he got tired of his drawer-opening and lamp-testing and towel-stacking, and escorted me up to the twelfth. I led him out with a five spot clutched in his fist and the leer even stronger.

If he expected me to race downstairs as soon as he was out of ear-shot, he was mistaken, for I hit the sack like the proverbial ton of crushed mortar. It had been literally weeks since I'd had a pleasant, restful sleep that was not broken by fitful dreams and worry-insomnia. Now that we had something solid to work on, I could look forward to some concrete action instead of merely feeling pushed around.
