someplace where it's warm."

"Sure. I got the bottle. Want a drink?"

Parks took the bottle, opened it, and took a good belt out of it.

"Hooh!" he breathed. "Pretty smooth."

As Clayton drank, Parks said: "Hey! I better get back to the field! I know! We can go to the men's room and finish the bottle before the ship takes off! Isn't that a good idea? It's warm there."

They started back down the street toward the spacefield.

"Yep, I'm from Indiana. Southern part, down around Bloomington," Parks said. "Gimme the jug. Not Bloomington, Illinois—Bloomington, Indiana. We really got green hills down there." He drank, and handed the bottle back to Clayton. "Pers-nally, I don't see why anybody'd stay on Mars. Here y'are, practic'ly on the equator in the middle of the summer, and it's colder than hell. Brrr!

"Now if you was smart, you'd go home, where it's warm. Mars wasn't built for people to live on, anyhow. I don't see how you stand it."

That was when Clayton decided he really hated Parks.

And when Parks said: "Why be dumb, friend? Whyn't you go home?" Clayton kicked him in the stomach, hard.

"And that, that—" Clayton said as Parks doubled over.

He said it again as he kicked him in the head. And in the ribs. Parks was gasping as he writhed on the ground, but he soon lay still.

Then Clayton saw why. Parks' nose tube had come off when Clayton's foot struck his head.

Parks was breathing heavily, but he wasn't getting any oxygen.

That was when the Big Idea hit Ron Clayton. With a nosepiece on like that, you couldn't tell who a man was. He took another drink from the jug and then began to take Parks' clothes off.

The uniform fit Clayton fine, and so did the nose mask. He dumped his own clothing on top of Parks' nearly nude body, adjusted the little oxygen tank so that the gas would flow properly through the mask, took the first deep breath of good air he'd had in fifteen years, and walked toward the spacefield.

He went into the men's room at the Port Building, took a drink, and felt in the pockets of the uniform for Parks' identification. He found it and opened the booklet. It read:

PARKINSON, HERBERT J.
Steward 2nd Class, STS

Above it was a photo, and a set of fingerprints.

Clayton grinned. They'd never know it wasn't Parks getting on the ship.

Parks was a steward, too. A cook's helper. That was good. If he'd been a jetman or something like that, the crew might wonder why he wasn't on duty at takeoff. But a steward was different.

Clayton sat for several minutes, looking through the booklet and drinking from the bottle. He emptied it just before the warning sirens keened through the thin air.

Clayton got up and went outside toward the ship.

"Wake up! Hey, you! Wake up!"

Somebody was slapping his cheeks. Clayton opened his eyes and looked at the blurred face over his own.

From a distance, another voice said: "Who is it?"

The blurred face said: "I don't know. He was asleep behind these cases. I think he's drunk."

Clayton wasn't drunk—he was sick. His head felt like hell. Where the devil was he?

"Get up, bud. Come on, get up!"

Clayton pulled himself up by holding to the man's arm. The effort made him dizzy and nauseated.

The other man said: "Take him down to sick bay, Casey. Get some thiamin into him."

Clayton didn't struggle as they led him down to the sick bay. He was trying to clear his head. Where was he? He must have been pretty drunk last night.

He remembered meeting Parks. And getting thrown out by the bartender. Then what?

Oh, yeah. He'd gone to the Shark's for a bottle. From there on, it was mostly gone. He remembered a fight or something, but that was all that registered.

The medic in the sick bay fired two shots from a hypo-gun into both arms, but Clayton ignored the slight sting.

"Where am I?"

"Real original. Here, take these." He handed Clayton a
