ordinary and harmless— I am not interested in you. I am interested in finding three saboteurs, three Terrans, two men and a woman, who have committed an incredible act of destruction and violence. They are said to have fled to this ship." Murmurs of surprise and indignation broke out on all sides. The Leiter motioned the soldiers to follow him up the aisle. "Two hours ago a Martian city was destroyed. Nothing remains, only a depression in the sand where the city was. The city and all its people have completely vanished.
