The two men walked toward the source of the sound. Tchassen couldn't allow himself to run, even to help Tynia; the exertion would have been too much for him. There was another clatter of shots and Tchassen recognized the gunfire of the primitive Earth weapons. In the darkness it was vaguely disturbing, but not frightening. Both Tynia and Drein were armed with dispersal rays; they would have no trouble defending themselves. Sudden footsteps pelted toward them. Tynia ran from a dark side street and threw herself into the Captain's arms. She clung to him, trembling and panting for breath. "Where's Drein?" he demanded. "The Corporal--he took my gun. He tried to kill me!" "Tynia, do you understand what you're saying? The accusation--" "You told us to stay together. I did my best. I was going through a house when I realized suddenly that I was alone. I saw Drein outside; I thought he was talking to someone. I ran out and--" She bit her lip and hid her eyes against his shoulder. In a flat, emotionless voice, Tchassen asked, "Drein was with Earthmen?" "I don't know! Someone sprang at me and knocked the ray out of my hands. I saw people--I thought I saw people--in the shadows behind Corporal Drein. I began to run. I don't want to accuse him of--of anything, Captain. I can't be sure. If he's an Earthman, we have to--we have to dispose of him, and I wouldn't want--" Her voice trailed off in a gasp of terror as they heard a new burst of gunfire, very close. Tchassen dodged aside, pulling Tynia behind a tree. Sergeant Briggan fired blindly into the night. His dispersal beam danced across the face of a frame building and the house exploded into flame. In the red glare of the fire, Tchassen saw a band of savages, dressed in animal hides--no that was impossible!--fleeing into the darkness beyond the village. Corporal Drein staggered toward them. Blood spilled from a gash torn in his chest. He saw Tchassen, Tynia and the Sergeant standing together. Like a man in a daze, he began to raise his dispersal ray. In Tchassen's mind there was no longer any room for doubt; the truth was clear. Drein was an Earthman; Drein had betrayed the station; Drein now intended to kill off the only survivors. The Captain acted with military decision. He pressed the firing stud of his weapon. Drein screamed in agony as he died. Tynia buried her face in her hands. Briggan put his arm around her. In the flickering light, Tchassen saw the Sergeant grin. "You didn't have to kill him, Captain," Tynia whispered. "After what you told me--" "Don't blame me; I didn't do anything!" "He was going to fire at us, wasn't he?" "You don't know that for sure. Maybe he was asking for help!" Tchassen shrugged; there was no accounting for the emotional inconsistencies of a woman. "What did you expect to prove by murdering Drein?" Briggan asked. "I saved us from--" "If he was an Earthman, why were the bandits firing at him? Why had they wounded him?"
