"We found you that way. You know. And we brought you back to life. You owe us that." "Indeed I do." "Then for your life, we demand our life in return." "I do not understand." "Your life is yours. We ask that you say nothing of us--for we feel that we will die if we are found. At least, the integrity of Ertene is at stake. In any event, we will not be taken, you may as well know that. And when I say die, I mean that Ertene will not go on living in the way we want her to live. Therefore you will disclose nothing that will point our way to anyone." "And you are willing that I should return to Terra with such an oath? What of my oath to Terra?" "Do you feel that your presence on Ertene will benefit Terra in some small way?" asked Charalas. "Now that you have given me the things we spoke of before, I do." "Then," said Charalas, "consider this point. You may not return unless you swear to keep us secret. You may not give Terra the benefit of your knowledge unless you deprive them of Ertene. Is that clear?" "If I may not return to Terra, and may not remain on Ertene, I can guess the other alternative and will admit that I do not like it. On the returning angle, about all I can do is to justify myself in my own mind that I have done all that I can by bringing these scientific items back with me. Since doing the best I can for Terra includes keeping your secret, I can do that also. But tell me, how do you hope to cover the fact that I've been missing for almost a year? That will take more than mere explanation." * * * * * "The process is easy," said Charalas. "We have one of the lifeships from the derelict. It was slightly damaged in the blast. It is maneuverable, but unwieldy. Evidence has been painstakingly forged. Apparently you will have broken your straps under the shock of the blast--and before the torture reached its height--and you found yourself in a derelict with no one left alive but yourself. You were hurt, mentally, and didn't grasp the situation clearly. There was no way to signal your plight in secrecy, and open signaling would have been dangerous since you were too close to Mars. "You found the lifeship and waited until you could safely take off. The derelict took a crazy course, according to the recorded log in your own handwriting, and headed for interstellar space. You took off at the safe time and have been floating free in the damaged lifeship. You've been on a free orbit for the best part of a year." "Sounds convincing enough."
