"It's a jet hypodermic, folks," he said.

He took the cube away and there was the welt to substantiate his statement.

"Hope we got to her in time," he said. "The plague is tough. Now I guess there's nothing for us to do but wait, maybe for quite a while."

I felt shaken beyond all recognition.


"Pop, you old caveman detective!" I burst out. "When did you get that idea for a steel hospital?" Don't think I was feeling anywhere near that gay. It was reaction, close to hysterical.

Pop was taken aback, but then he grinned. "I had a couple of clues that you and Alice didn't," he said. "I knew there was a very sick woman involved. And I had that bout with Los Alamos fever I told you. They've had a lot of trouble with it, I believe—some say its spores come from outside the world with the cosmic dust—and now it seems to have been carried to Atla-Hi. Let's hope they've found the answer this time. Alice, maybe we'd better start getting some water into this gal."

After a while we sat down and fitted the facts together more orderly. Pop did the fitting mostly. Alamos researchers must have been working for years on the plague as it ravaged intermittently, maybe with mutations and ET tricks to make the job harder. Very recently they'd found a promising treatment (cure, we hoped) and prepared it for rush shipment to Atla-Hi, where the plague was raging too and they were sieged in by Savannah as well. Grayl was picked to fly the serum, or drug or whatever it was. But he knew or guessed that this lone woman observer (because she'd fallen out of radio communication or something) had come down with the plague too and he decided to land some serum for her, probably without authorization.

"How do we know she's his girlfriend?" I asked.

"Or wife," Pop said tolerantly. "Why, there was that bag of woman's stuff he was carrying, frilly things like a man would bring for a woman. Who else'd he be apt to make a special stop for?
