Two Martians stood in the doorway, with Merlo in the lead. The greenish face of the other was seamed and wrinkled, and the crest atop his head was shrunken and tattered at the edges. He walked with a stoop, his movements slow and deliberate. Under his arm he carried a bundle of Earth clothing. "Klev," Susan called. "Tec qua hala mo."
