"It's very simple. Distance, as you Earthlings regard it, is not distance at all. s.p.a.ce bends to a greater or lesser degree depending upon its immediate function in whatever time-s.p.a.ce equation you are using."

"Thank you very much," Kirk replied and silently added: Keep to the line. Hold to your own values. On Earth, wherever it is, a man is waiting to go to the chair for a murder he didn't commit. Use whatever equation you want to--that still adds up the same. These people may be a lot smarter than you are, but they can't twist that one and make you believe it comes out any different.

A strange city of graceful flying spirals was coming over the horizon.

It moved closer and the air car arced in to a halt on a huge cement landing area punctuated with small circles of a different material.

Raima jumped from the c.o.c.kpit and Kirk followed to hear the soft thud of the cat's four paws landing beside him. The cat went over and sat down on one of the circles. Raima followed, stood beside the animal and called, "Don't you want to go down to street level?"

"Of course. How stupid of me not to know how."

The circle dropped silently beneath them in a bright metal tube in which a door soon appeared to let them out into a broad street filled with casually moving pedestrians. Kirk noted that none of them seemed in any hurry; that here and there was an individual dressed like himself.

Watchers on furlough or vacation, he thought a trifle bitterly. This picture was far from complete but enough of it added up to furnish a name for them. Quizling was a good one. Perhaps traitor was better.

All in all, he found one satisfaction. He could travel about as he pleased.

A short walk brought them to a huge four or five story wall, the like of which Kirk had never seen. It was symmetrically covered with small, opaque, gla.s.s windows, beside each of which was a dial not unlike the ones on Earth telephones. Catwalks of some bright metal covered the wall. On these catwalks, numerous people were busy with a strange business Kirk could not follow.

"This is the video-directory," Raima said. She gave no further explanation, but while Rondo lazily rubbed noses with a bear cub sitting on its haunches waiting for its master, she spun the dial with practiced efficiency. "Now, if Naia North is in the city and wishes to see you, her image will appear in the mirror."

As Kirk watched and the bear slapped the grinning tiger with a playful paw, the opaque gla.s.s cleared and the tall, willowy figure of Naia North appeared in miniature.

"You may speak in here," Raima said, solemnly indicating a small screened opening beside the mirror. "My! She's pretty, isn't she?"

Naia North was entirely composed. She wore a pale blue gown and from the background in the mirror, Kirk gathered that she was at home. "Aren't you surprised?" Kirk asked.

Now a slight frown creased the lovely Naia's brow. "A little perhaps.

How did you get to Mythox? And why did you come?"

"A slight matter of murder. A murder you confessed to, or has it slipped your mind?"

"Aren't you being rather absurd? That's all done with."

"Not so far as Paul Cordell is concerned. He's going to the chair--only he isn't. We're going back and straighten a few things out."

Genuine surprise was reflected now. And possibly a certain contempt. "My opinion of you lessens. I hadn't rated you as a complete fool. How did you get here?"

"The same way you did I suppose, is there more than one way?"

Naia's frown deepened. "Do you mean you were _brought_--?"

"Not intentionally, I stowed away on that funny round ship that doesn't go anywhere and travels far."

The beautiful brow immediately cleared. "Oh, I see," Naia observed with amus.e.m.e.nt. "And you know exactly how you'll get me back to Earth I suppose? Thousands of light years. It's a long walk."

"I'll take one thing at a time and worry about them in order of appearance. The main thing for you to remember, is this: You may be as smart as all get out but you broke an American law on American soil by your own confession and by G.o.d you're going back and answer for it!"

"Idiot! I can have you--"

Kirk's mood changed to the quizzical. "It's entirely beside the point, but still I don't get you, baby. Why the switcheroo? You walked in and confessed. Then you took a powder. Now you sneer in my teeth. What do you use for a rudder, sweetheart?"

"I followed orders," Naia flared with a mixture of anger and sullenness.

"I am now free of the a.s.signment."

Kirk pursed his lips thoughtfully. "You wouldn't be sort of a hatchet-woman for this high-blown outfit, would you? I can think offhand of a few other names. Karney, Blatz, Kennedy. What gives with knocking off nuclear physicists, baby?"

Naia did not answer. When she started to turn away from the mirror, Kirk glanced at the silent Raima standing with her hand on the tiger's head.

"Is there any way I can call on the lady in the mirror personally?"

"Not if she doesn't want to receive you," Raimu said. She was studying Kirk, with wistful dark eyes.

Naia turned back quickly. "I'll be glad to receive you. It's time I taught you a lesson."

"Fine. What's your address?"

But Naia was gone. The little mirror turned opaque. Kirk shot a questioning glance at Raimu. "Does yes mean no on this c.o.c.keyed planet?"

"Her car will come." Raima murmured. But the pet.i.te dark beauty seemed interested in other things. "You didn't tell me your name."

"Sorry. Rude of me. It's Martin Kirk. You've been pretty nice to me. I wish there was some way I could show my appreciation."

"You're going to see Naia North?"

"Yes. She's a murderess. I'm taking her back to my planet."

"I'm afraid that wouldn't be possible."

"You too, honey?" Kirk reached out and flicked one of the raven curls.

"If things were different you and I might be able to have fun."

"I spend a lot of time--where you found me. Maybe--"

"I doubt if I can make it. But keep your clothes on after this--as a personal favor to me."

She was the very soul of solemnity. "I don't understand you. I really don't understand you at all."

At that moment, an air car--much smaller than Raima's, dropped gently into the street beside Kirk. "Good lord! Did this thing smell me out?"

"It came to the mirror on Naia's private wave-length. Get in. It will take you to her."

Kirk crawled into the car. The last thing he saw before it lifted into the air, were Raima's dazzling black eyes. The last words he heard were, "Goodbye, Martin Kirk. I will visualize you."

The car swung up above the graceful, spidery b.u.t.tresses and moved across the city. Kirk filled in the time by trying to figure out what made the thing go. He hadn't gotten to first base when the car lost alt.i.tude and came to rest on a balcony hung with seeming perilousness on a sheer white wall. Kirk stepped out. A large gla.s.s panel had been pushed back and Naia stood waiting in the opening.

"Nice of you to receive me," Kirk said. "Have you got your bags packed for a trip stateside?"

"Please come this way."
