What have you done with her? You'd better tell me. You can have me court-martialed, but you can't stop me from talking. I can prove she was there. The grate—" "The grate? What are you talking about? There was no ripped-out grate. The grate was in place. I feel very sorry for you, Lieutenant. But I can't let sympathy stand in the way of my duty. In some respects you're very rational. You can think logically and clearly ... up to a point. But the shock weakness is there. It's very serious when you start having actual hallucinations." The executive officer had drawn his gun. He was holding it rather loosely in his hand now, triggered and ready for any dangerous or suspicious move on Corriston's part. There was nothing in Clement's gaze as he swung about to refute the dark mistrust that had come into the executive officer's eyes. He seemed intent only on bolstering that mistrust by driving even deeper nails into Corriston's coffin. "I'm afraid we'll have to continue to regard Lieutenant Corriston as dangerously unstable," he said. "Keep your gun on him when you take him back to the Ward. Don't relax your vigilance for an instant." "I won't," the executive officer promised. "Good. You're not going to make any further trouble for us, are you, Lieutenant?" The question seemed to call for no answer and Corriston made none. He turned slowly and walked toward the door, despairingly aware that a man he had rather liked had fallen into step behind him and would shoot him dead if he so much as wavered. Just as he reached the door Clement spoke again, giving the executive officer final instructions. "He must not be permitted to leave his cell. Make sure of that, Simms. Post a permanent guard at the door. He must be kept under constant surveillance. If he's the self-destructive type, and I'm by no means sure he isn't, he may attempt to kill himself." 9 May attempt to kill himself. May attempt.... May attempt.... May attempt to kill himself. Corriston sat up on his cot, his mouth dry, his temples pounding. Had Clement implanted the suggestion in his mind deliberately, with infinite cruelty and cunning? Was Clement really hoping that he would commit suicide? If he took his own life Clement would stand to gain a great deal.
