each other's verity, if the conflict is in their interpretations of the facts they narrate...." Manual, Interstellar Medical Service. P. 43. They brought the prisoner a bare hour later. Sturdy, grizzled men had strung a line to the Med ship's power bank, and there was that small humming sound which nobody quite understands as power flowed into the Duhanne cells. The power men regarded the inside of the ship without curiosity, as if too much absorbed in private bitterness to be interested in anything else. When they had gone, a small guard brought the prisoner. Calhoun noted the expression on the faces of these men, too. They hated their prisoner. But their faces showed the deep and wrenching bitterness a man does feel when his children have abandoned him for companions he considers worthless or worse. A man hates those companions corrosively, and these men hated their prisoner. But they could not help knowing that he, also, had abandoned some other father whose feelings were like their own. So there was frustration even in their fury. The prisoner came lightly up the ladder into the Med ship. He was a very young man, with a singularly fair complexion and a carriage at once challengingly jaunty and defiant. Calhoun estimated his age as seven years less than his own, and immediately considered him irritatingly callow and immature because of it. "You're my jailer, eh?" said the prisoner brightly, as he entered the Med ship's cabin. "Or is this some new trick? They say they're sending me back. I doubt it!" "It's true enough," said Calhoun. "Will you dog the air-lock door, please? Do that and we'll take off." The young man looked at him brightly. He grinned. "No," he said happily. "I won't." Calhoun felt ignoble rage. There had been no great purpose in his request. There could be none in the refusal. So he took the prisoner by the collar and walked him into the air lock. "We are going to be lifted soon," he said gently. "If the outer door isn't dogged, the air will escape from the lock. When it does, you will die. I can't save you, because if the outer door isn't dogged, all the air in the ship will go if I should try to help you. Therefore I advise you to dog the door." He closed the inner door. He looked sick. Murgatroyd looked alarmedly at him.
