From the books I've read I am well aware of one of the fundamental principles of running an underground: Keep it underground! The Commie menace in these United States might have won out in the middle of the century if they'd been able to stay a secret organization. So the Highways in Hiding could stay underground and be an efficient organization only until someone smoked them out.

That one was going to be me.

But I needed an aide-de-camp. Especially and specifically I needed a trained telepath, one who would listen to my tale and not instantly howl for the nut-hatch attendants. The F.B.I. were all trained investigators and they used esper-telepath teams all the time. One dug the joint while the other dug the inhabitant, which covered the situation to a faretheewell.

It would take time to come up with a possible helper. So I spent the next hour driving toward Chicago, and by the time I'd crossed the Ohio-Indiana line and hit Richmond, I had a plan laid out. I placed a call to New York and within a few minutes I was talking to Nurse Farrow.

I'll not go into detail because there was a lot of mish-mash that is not particularly interesting and a lot more that covered my tracks since I'd parted company with her on the steps of the hospital. I did not, of course, mention my real purpose over the telephone and Miss Farrow could not read my mind from New York.

The upshot of the deal was that I felt that I needed a nurse for a while, not that I was ill, but that I felt a bit woozy now and then because I hadn't learned to slow down. I worked too fast and too long and my condition was not up to it yet. This Miss Farrow allowed as being quite possible. I repeated my offer to pay her at the going prices for registered nurses with a one-month guarantee, paid in advance. That softened her quite a bit. Then I added that I'd videograph her a check large enough to cover the works plus a round trip ticket. She should come out and have a look, and if she weren't satisfied, she could return without digging into her own pocket. All she'd lose was one day, and it might be a bit of a vacation if she enjoyed flying in a jetliner at sixty thousand feet.

The accumulation of offers finally sold her and she agreed to arrange a leave of absence. She'd meet me in the morning of the day-after-tomorrow, at Central Airport in Chicago.

I videographed the check and then took off again, confident that I'd be able to sell her on the idea of being the telepath half of my amateur investigation team.

Then because I needed some direct information, I turned West and crossed the line into Indiana, heading toward Marion. So far I had a lot of well-placed suspicions, but until I was certain, I could do no more than postulate ideas. I had to know definitely how to identify Mekstrom's Disease, or at least the infected flesh. I have a fairly good recall; all I needed now was to have someone point to a Case and say flatly that this was a case of Mekstrom's Disease. Then I'd know whether what I'd seen in Ohio was actually one hundred percent Mekstrom.
