Harris walked slowly down the hall. It was after six; the evening meal was over. A dim concept was coming into his mind, but it was much too soon to be sure. He increased his pace, turning right at the end of the hall. Two nurses passed, hurrying by. Westerburg was quartered with a buddy, a man who had been injured in a jet blast and who was now almost recovered. Harris came to the dorm wing and stopped, checking the numbers on the doors.
"Can I help you, sir?" the robot attendant said, gliding up.
"I'm looking for Corporal Westerburg's room."
"Three doors to the right."
Harris went on. Asteroid Y-3 had only recently been garrisoned and staffed. It had become the primary check-point to halt and examine ships entering the system from outer space. The Garrison made sure that no dangerous bacteria, fungus, or what-not arrived to infect the system. A nice asteroid it was, warm, well-watered, with trees and lakes and lots of sunlight. And the most modern Garrison in the nine planets. He shook his head, coming to the third door. He stopped, raising his hand and knocking.
"Who's there?" sounded through the door.
"I want to see Corporal Westerburg."
The door opened. A bovine youth with horn-rimmed glasses looked out, a book in his hand. "Who are you?"
"Doctor Harris."
