Her sobs gradually died away. She straightened slowly until he no longer had to support her, but all the vitality and resilience was gone out of her body. "All right," she said in a lifeless voice. "You'll come back, Peter."
He turned away suddenly, not trusting himself to kiss her goodbye. A line from an old film kept echoing through his head. "They'll come back—but not as boys!"
We'll come back, but not as men.
We'll come back, but not as elephants.
We'll come back, but not as octopi.
He was trembling violently. He ran the last few steps, stumbled into the airlock, and pressed the stud that would seal the door behind him. We'll come back.... He heard the massive disk sink home, closing him off. Then he sank down on the floor of the airlock and put his head in shaking hands.
After a while he roused himself, closed the inner door of the lock behind him, and walked down the long corridor into the control chamber. The shining banks of keys were there, waiting for his touch; he slumped down before them and listlessly closed the contact of the visiplate.
He swung its field slowly, scanning for the last time the bare walls of the underground chamber, making sure that all the spectators had retired out of the way of the blast. Then his clawed fingers poised over the keys, hovered a moment, and thrust down.
Acceleration pressed him deep into his chair. In the visiplate, the heavy doors that closed the tunnel above him flashed back, one by one. The energy-charged screen flickered off to let him pass, and closed smoothly behind him. The last doors, cleverly camouflaged, slipped back into place and then dwindled in the distance. It was done.
