" Give me your word as a Tribesman that you won’t double-cross me.” Even I know how valuable such a vow is. “I don’t trust you otherwise.” “You have my word.” He shoves me forward, and I stumble, just catching myself from falling. Swine! I bite my lip to keep from saying it. Let him think he’s cowed me. Let him think he’s won. Soon, he’ll realize his mistake: He vowed to play fair. But I didn’t. "
