"He harms me by not helping me or allowing me to seek help elsewhere. If he were a robot, he would be violating the First Law."

Canute stepped to the foot of the table where Ariel was confined, and placed one steel hand on the bar across her feet. "But he is not a robot. If our studies of the Laws of Humanics have taught us anything, it is that humans are not subject to the Laws of Robotics.

"You are not in immediate danger. I cannot help you."

"It's very simple," Ariel said. "The longer I stay on Robot City, the more insane I become. The longer Derec stays, the longer he lives without any knowledge of who he is-a state that I think you'll agree is also causing him some anguish. Anguish is harm, too."

Canute's hand raised from the bar, then slowed to a stop in midair. "I think I agree, but Dr. Avery is my creator. He has instructed me that you are not in danger. I cannot supersede his judgment with my own."

"If Dr. Avery does not have our well-being at heart, who does? Who is responsible? I believe it's you, the robot he left in charge."

That's brilliant,thought Derec. I knew there was some reason why I liked this girl! "She's right, Canute. The same morality that troubled you for what you did to Lucius will trouble you if you allow Dr. Avery to harm us through inaction. You cannot say with any certainty that we'll get the medical attention we need."

Canute's slow turn toward Derec showed the positronic conflicts it was experiencing. Derec pursued his point.

"If the robots of Robot City are allowed to continue creating, they will be able to serve humanity better, but Dr. Avery will stop this process. His orders are not mentally incompetent, but they are morally incompetent. Are you still bound to obey them?"

The robot's turn slowed to immobility. This was the crisis, Derec knew, where Canute would decide for or against them-or slip into positronic drift.

Canute said nothing for several seconds. Then. "But, Master Derec, how can I say with any certainty that the two of you will have proper attention while you are in space? Is it not likely that you'll suffer while alone on your way to your destination?"

"The answer to that question is simple," said Derec, forcing his voice to remain calm and reasonable. "That's where Wolruf and Mandelbrot come in. They'll take care of us between the stars."

This time Canute did not speak or move for several minutes. It was all Derec could do to stop himself from adding something more to convince the robot to do what he wanted, but he was too afraid that the information already provided had confused the robot's integrals to a dangerous degree.

"I have been thinking," Canute finally said, "of Dr. Avery's exact words. He said I should not touch the bars restraining our friend Derec, but he said nothing about the bars restraining our friends Ariel and Wolruf."

That's the spirit!Derec thought with a grin.

Wordlessly, Canute walked to the end of Ariel's slab, grabbed the bar across her feet, and, utilizing all his strength, pulled it away.

Dr. Avery's spaceship, a luxurious model equipped to handle as many as ten human-size occupants, was hidden in a cave on the outskirts of the city. After Canute had left the foursome-with really no idea of what to tell Dr. Avery except the truth about how his prisoners had escaped-it was a comparatively simple matter for Derec and the reactivated Mandelbrot to deduce how to run the controls.

"Let's get off this place!" said Ariel. "We can plot a course for a destination later. I don't even care if we head toward the colonies, I just want to go somewhere as soon as possible."

"Don't you care about the possibility that you might catch a disease?" asked Derec.

"It's too late for that," said Ariel. "Besides, right now I think a colony will be the only place that will take us."

After they were safely in space, and free to wander about as they chose, Mandelbrot inspected the radio equipment and said, "Master Derec, I believe someone is trying to send us a transmission.”

“It's probably Dr. Avery, but switch it on anyway," said Derec. "We might as well hear what he has to say." He smiled as Wolruf's lip curled up over her teeth in anticipation of what they would hear.

But instead of the irate words of Dr. Avery, they heard a familiar form of music, a tune played in twenty measures, over and over in an A-flat chord, with sounds weaving in and out of dominant chords over a pulsating, unforgettable rhythm. Derec listened to it for only ten measures before his foot began tapping.

"That's wonderful!" said Ariel. "It's The Three Cracked Cheeks!"

"Sayin' farrewell," said Wolruf softly. "Maybe neverr see ther like again."

"Yes, I'm going to miss them," said Derec softly.

"The signal is becoming weaker, already beginning to fade," said Mandelbrot.

"We're traveling fast," said Ariel. "I think we'd better decide where."

"Later, if you don't mind," said Derec. "Sorry, but I can't muster up a definite opinion right now. I'm too drained." He got out of his seat and slumped to the floor, leaning against the wall of the ship. He felt strange inside, oddly disjointed. For weeks he had labored to escape from Robot City, and now that he had, he already missed it, already wondered how the mysteries he had uncovered would ultimately be resolved. He might never know the answers.

Just as he might never again hear the music of the Three Cracked Cheeks. The sound on the radio gradually faded, replaced by white noise, and he gestured at Mandelbrot to switch it off. He missed the music at once. He even missed Harry's jokes.

Well, at least now he had the opportunity to achieve the two greatest goals he had at the moment. Somewhere in the universe would be the secret of his amnesia, and he was determined to find a cure for Ariel at all costs.

Perhaps then he would be able to return to Robot City.

He glanced up as Wolruf made her way to the food dispensary. She clumsily punched a few buttons with her paw, and then waited for the food to appear in the slot.

But instead of food, they saw something that made them gasp.

Inthe slot was a Key to Perihelion!

DR. AVERY (and his lab): As a young man, Dr. Avery was compared to Frank Lloyd Wright as a visionary architect and urban planner. As his interests turned to robotics, however, he was influenced by Kelden Amadiro, the head of the Robotics Institute on Aurora. Avery took Amadiro's idea of using humaniform robots to build new, ready-made colonies for the Spacers and transformed it into a huge experiment in robotics and social dynamics-Robot City. With the sponsorship and funding of Juliana Welsh, he created Robot City and then disappeared.

[For himself he established two facilities on Robot City: an apartment in the Compass Tower and a complete laboratory. The laboratory provides full equipment for the most advanced robotics procedures, and a fairly complete set of medical, diagnostic and treatment equipment. It is here that Dr. Avery exercises the creative genius that enabled him to invent the cellular robotic chips that comprise most of Robot City.]

[THE NEW GLOBE THEATRE: The New Globe designed by Canute is based on the spotty written records of the original Globe that survive from Shakespeare's day. The theatre is roughly circular in shape. Its stage is thrust forward, with the dressing rooms, storage space and electronic equipment directly behind. The audience surrounds the stage on the other three sides. A canopy partially covers the stage, supported by the primary structure upstage and two narrow columns about halfway downstage. The three trap doors on the stage permit entry from below.
