Minnim shook his head. "If we could send whom we pleased, we would have sent someone out ten years ago, when these conclusions were first being arrived at. This is our first excuse to send someone and they ask for a detective and that suits us. A detective is a sociologist, too; a rule-of-thumb, practicing sociologist, or he wouldn't be a good detective. Your record proves you a good one."
"Thank you, sir," said Baley mechanically. "And if I get into trouble?"
Minriim shrugged. "That's the risk of a policeman's job." He dismissed the point with a wave of his hand and added, "In any case, you must go. Your rime of departure is set. The ship that will take you is waiting."
Baley stiffened. "Waiting? When do I leave?"
"In two days."
"I've got to get back to New York then. My wife - "
"We will see your wife. She can't know the nature of your job, you know. She will be told not to expect to hear from you."
"But this is inhuman. I must see her. I may never see her again." Minnim said, "What I say now may sound even more inhuman, but isn't it true that there is never a day you set about your duties on which you cannot tell yourself she may never see you again? Plainclothesman Baley, we must all do our duty."
Baley's pipe had been out for fifteen minutes. He had never noticed it.
No one had more to tell him. No one knew anything about the murder. Official after official simply hurried him on to the moment when he stood at the base of a spaceship, all unbelieving still.
It was like a gigantic cannon aimed at the heavens, and Baley shivered spasmodically in the raw, open air. The night closed in (for which Baley was thankful) like dark black walls melting into a black ceiling overhead. It was cloudy, and though he had been to Planetaria, a bright star, stabbing through a rift in the cloud, startled him when it caught his eyes.
A little spark, far, far away. He stared curiously, almost unafraid of it. It looked quite close, quite insignificant, and yet around things like that circled planets of which the inhabitants were lords of the Galaxy. The sun was a thing like that, he thought, except much closer, shining now on the other side of the Earth.
He thought of the Earth suddenly as a ball of stone with a film of moisture and gas, exposed to emptiness on every side, with its Cities barely dug into the outer rim, clinging precariously between rock and air. His skin crawled!
The ship was a Spacer vessel, of course. Interstellar trade was entirely in Spacer hands. He was alone now, just outside the rim of the City. He had been bathed and scraped and sterilized until he was considered safe, by Spacer standards, to board the ship. Even so, they sent only a robot out to meet him, bearing as he did a hundred varieties of disease germs from the sweltering City to which he himself was resistant but to which the eugenically hot housed Spacers were not.
The robot bulked dimly in the night, its eyes a dull red glow.
"Plainclothesman Elijah Baley?"
"That's right," said Baley crisply, the hair on the nape of his neck stirring a bit. He was enough of an Earthman to get angry goose flesh at the sight of a robot doing a man's job. There had been R. Daneel Olivaw, who had partnered with him in the Spacer murder affair, but that had been different. Daneel had been - "You will follow me, please," said the robot, and a white light flooded a path toward the ship.
Baley followed. Up the ladder and into the ship he went, along corridors, and into a room.
The robot said, "This will be your room, Plainclothesman Baley. It is requested that you remain in it for the duration of the trip."
Baley thought: Sure, seal me off. Keep me safe. Insulated.
The corridors along which he had traveled had been empty. Robots were probably disinfecting them now. The robot facing him would probably step through a germicidal bath when it left.
The robot said, "There is a water supply and plumbing. Food will be supplied. You will have viewing matter. The ports are controlled from this panel. They are closed now but if you wish to view space - "
Baley said with some agitation, "That's all right, boy. Leave the ports closed."
He used the "boy" address that Earthmen always used for robots, but the robot showed no adverse response. It couldn't, of course. Its responses were limited and controlled by the Laws of Robotics.
The robot bent its large metal body in the travesty of a respectful bow and left.
Baley was alone in his room and could take stock. It was better than the plane, at least. He could see the plane from end to end. He could see its limits. The spaceship was large. It had corridors, levels, rooms. It was a small City in itself. Baley could almost breathe freely.
Then lights flashed and a robot's metallic voice sounded over the communo and gave him specific instructions for guarding himself against take-off acceleration.
There was the push backward against webbing and a yielding hydraulic system, a distant rumble of force-jets heated to fury by the proton micro-pile. There was the hiss of tearing atmosphere, growing thinner and high-pitched and fading into nothingness after an hour.
They were in space.
It was as though all sensation had numbed, as though nothing were real. He told himself that each second found him thousands of miles farther from the Cities, from Jessie, but it didn't register.
On the second day (the third? - there was no way of telling time except by the intervals of eating and sleeping) there was a queer momentary sensation of being turned inside out. It lasted an instant and Baley knew it was a Jump, that oddly incomprehensible, almost mystical, momentary transition through hyperspace that transferred a ship and all it contained from one point in space to another, light years away. Another lapse of time and another Jump, still another lapse, still another Jump.
