A croak was all I managed. The skinny one was unwrapping me. My legs sagged apart and hurt. "Get up!"

I tried and didn't make it. Skinny grabbed one of my legs and started to knead it.

I screamed.

"Here, lemme do that," said Fatty. "I used to be a trainer."

Fats did know something about it. I gasped when his thumbs dug into my calves and he stopped. "Too rough?" I couldn't answer. He went on massaging me and said almost jovially, "Five days at eight gravities ain't no joy ride. But you'll be okay. Got the needle, Tim?"

The skinny one jabbed me in my left thigh. I hardly felt it. Fats pulled me to a sitting position and handed me a cup. I thought it was water; it wasn't and I choked and sprayed. Fats waited, then gave it to me again. "Drink some, this time." I did.

"Okay, up on your feet. Vacation is over."

The floor swayed and I had to grab him until it stopped. "Where are we?" I said hoarsely.

Fats grinned, as if he knew an enormously funny joke. "Pluto, of course. Lovely place, Pluto. A summer resort."

"Shaddap. Get him moving."

"Shake it up, kid. You don't want to keep him waiting."

Pluto! It couldn't be; nobody could get that far. Why, they hadn't even attempted Jupiter's moons yet. Pluto was so much farther that.

My brain wasn't working. The experience just past had shaken me so badly that I couldn't accept the fact that the experience itself proved that I was wrong.

But Pluto!

I wasn't given time to wonder; we got into space suits. Although I hadn't known, Oscar was there, and I was so glad to see him that I forgot everything else. He hadn't been racked, just tossed on the floor. I bent down (discovering charley horses in every muscle) and checked him. He didn't seem hurt.

"Get in it," Fats ordered. "Quit fiddlin'."

"All right," I answered almost cheerfully. Then I hesitated. "Say-I haven't any air."

"Take another look," said Fats. I looked. Charged oxy-helium bottles were on the backpack. "Although," he continued, "if we didn't have orders from him, I wouldn't give you a whiff of Limburger. You made us for two bottles-and a rock hammer-and a line that cost four ninety-five, earthside. Sometime," he stated without rancor, "I'm gonna take it out of your hide."

"Shaddap," said Skinny. "Get going."

I spread Oscar open, wriggled in, clipped on the blood-color reader, and zipped the gaskets. Then I stood up, clamped my helmet, and felt better just to be inside. "Tight?"

("Tight!" Oscar agreed.)

"We're a long way from home."

("But we got air! Chin up, pal.")

Which reminded me to check the chin valve. Everything was working. My knife was gone and so were the hammer and line, but those were incidentals. We were tight.

I followed Skinny out with Fats behind me. We passed Wormface in the corridor-or a wormface-but while I shuddered, I had Oscar around me and felt that he couldn't get at me. Another creature joined us in the air lock and I had to look twice to realize that it was a wormface in a space suit. The material was smooth and did not bulge the way ours did. It looked like a dead tree trunk with bare branches and heavy roots, but the supreme improvement was its "helmet"-a glassy smooth dome. One-way glass, I suppose; I couldn't see in. Cased that way, a wormface was grotesquely ridiculous rather than terrifying. But I stood no closer than I had to.

Pressure was dropping and I was busy wasting air to keep from swelling up. It reminded me of what I wanted most to know: what had happened to Peewee and the Mother Thing. So I keyed my radio and announced: "Radio check. Alfa, Bravo, Coca-"

"Shaddap that nonsense. We want you, we'll tell you."

The outer door opened and I had my first view of Pluto.

I don't know what I expected. Pluto is so far out that they can't get decent photographs even at Luna Observatory. I had read articles in the Scientific American and seen pictures in LIFE, bonestelled to look like photographs, and remembered that it was approaching its summer-if "summer" is the word for warm enough to melt air. I recalled that because they had announced that Pluto was showing an atmosphere as it got closer to the Sun.

But I had never been much interested in Pluto-too few facts and too much speculation, too far away and not desirable real estate. By comparison the Moon was a choice residential suburb. Professor Tombaugh (the one the station was named for) was working on a giant electronic telescope to photograph it, under a Guggenheim grant, but he had a special interest; he discovered Pluto years before I was born.

The first thing I noticed as the door was opening was click... click... click-and a fourth click, in my helmet, as Oscar's heating units all cut in.

The Sun was in front of me-I didn't realize what it was at first; it looked no bigger than Venus or Jupiter does from Earth (although much brighter). With no disc you could be sure of, it looked like an electric arc.

Fats jabbed me in the ribs. "Snap out of your hop."

A drawbridge joined the door to an elevated roadway that led into the side of a mountain about two hundred yards away. The road was supported on spidery legs two or three feet high up to ten or twelve, depending on the lay of the land. The ground was covered with snow, glaringly white even under that pinpoint Sun. Where the stilts were longest, about halfway, the viaduct crossed a brook.

What sort of "water" was that? Methane? What was the "snow"? Solid ammonia? I didn't have tables to tell me what was solid, what was liquid, and what was gas at whatever hellish cold Pluto enjoyed in the "summer." All I knew was that it got so cold in its winter that it didn't have any gas or liquid-just vacuum, like the Moon.

I was glad to hurry. A wind blew from our left and was not only freezing that side of me in spite of Oscar's best efforts, it made the footing hazardous-I decided it would be far safer to do that forced march on the Moon again than to fall into that "snow." Would a man struggle before he shattered himself and his suit, or would he die as he hit?

Adding to hazard of wind and no guard rail was traffic, space-suited wormfaces. They moved at twice our speed and shared the road the way a dog does a bone. Even Skinny resorted to fancy footwork and I had three narrow squeaks.

The way continued into a tunnel; ten feet inside a panel snapped out of the way as we got near it. Twenty feet beyond was another; it did the same and closed behind us. There were about two dozen panels, each behaving like fast-acting gate valves, and the pressure was a little higher after each. I couldn't see what operated them although it was light in the tunnel from glowing ceilings. Finally we passed through a heavy-duty air lock, but the pressure was already taken care of and its doors stood open. It led into a large room.

Wormface was inside. The Wormface, I think, because he spoke in English: "Come!" I heard it through my helmet. But I couldn't be sure it was he as there were others around and I would have less trouble telling wart hogs apart.

Wormface hurried away. He was not wearing a space suit and I was relieved when he turned because I could no longer see his squirming mouth; but it was only a slight improvement as it brought into sight his rearview eye.

We were hard put to keep up. He led us down a corridor, to the right through another open double set of doors, and finally stopped suddenly just short of a hole in the floor about like a sewer manhole. "Undress it!" he commanded.

Fats and Skinny had their helmets open, so I knew it was safe, in one way. But in every other way I wanted to stay inside Oscar-as long as Wormface was around.

Fats undamped my helmet. "Out of that skin, bub. Snap it up!" Skinny loosened my belt and they quickly had the suit off even though I hindered.

Wormface waited. As soon as I was out of Oscar he pointed at the hole. "Down!"
