"My God!" he said. Susan's shoulders sagged. "We're through, and the Martians are finished too. And sooner or later he'll manage to wreck the New Governments also." "Damn it, we're still alive!" Nick exploded. "There's still a chance." She smiled weakly and brushed at her tears. Twice they passed side tunnels, and at a third opening turned in at a Martian's gesture. A short passage opened into a series of three rooms. Nick looked around. The glow-plates in the ceiling were the same as those in the abandoned surface cities, but far brighter. The first room was furnished with a single broad couch and three peculiar objects he decided were chairs. There were no shelves or cupboards, but niches had been cut into the smooth stone walls at irregular intervals. The second room was completely bare, giving the impression that furnishings had been recently removed. The blue-faced Martian emitted a series of chirps, and at once the creature around Nick's shoulders pulsated, uncoiled and fell to the floor with a dull thump. Nick jumped aside in distaste as it collected itself into a flattened ball and rolled toward the doorway. There it changed shape again, flowing into a slot in the door frame. "He says the varlu will kill us if we try to escape," Susan translated the Martian's chirpings. Nick decided that if there were any other possible escape route he would not try the doorway. "Mel nikko ne cho twa Klev?" Susan asked again. The Martians conferred, and finally the bluish one made a gesture of reluctant assent. All three withdrew. "Just who is this Klev?" Nick demanded. "Why did old Blueface get so bothered whenever you mentioned him?" "He's an old, old Martian," Susan explained. "He was dying of the Plague when Dad's experiments saved him. He remained our friend even when most of the others turned against us because of the Exploiters." "Who's Blueface?" "That's Merlo. He has the Plague and will die soon, just as the Martian who lived here must have died recently."
