So great had her bitterness become that, if she could have gotten off Callisto in any way, she would have deserted him. This would have meant forfeiting her marriage settlement and the sum that was in escrow. It would also have left her father in debt to Negu Mah for all that Negu Mah had given him. But Nanlo's passionate rebellion had reached such a state of ferment in her breast that she would have accepted all this to strike a blow at the plump, smiling man who now sat drinking molkai in their garden with their guest from Venus. The answer to that was--Negu Mah would not let her leave Callisto. The journey to earth, he logically argued, was still one containing a large element of danger. There was no reason for her to visit any other planet, and law and custom required that she look after their home while he himself was away on business. In this he was unshakeable. There was a stern and unyielding side to him, inherited perhaps from his Eastern ancestors, that left Nanlo shaken and frightened when it appeared. She had seen it the one time she had seriously gone into a tantrum in an effort to make him let her take a trip to earth. It had so startled and terrified her that she had never used those tactics again. But now, as she wheeled away the molkai decanter and left Negu Mah and Sliss to themselves, joy and exultation was singing in her. Doubly. For she was going to run away from Negu Mah, run away with the man she loved, and in their flight they were going to steal the Vulcan. Thus Negu Mah would be doubly punished. He would be hurt in his pride and in his pocketbook. And all through the Jupiter and Saturn systems, where his wealth, his position, and his beautiful wife were openly envied, he would be laughed at and derided. Humming lightly under her breath, Nanlo put the molkai decanter away in a little pantry and hurried on to her own apartment. Molkai was a powerful, though non-habit-forming drink. Under its influence one became talkative, but disinclined to movement. Sliss and her husband would remain as they were for hours, leaving her free to do as she would. The servants were asleep in another part of the building, and there was no one to note as she changed her clothes swiftly for a light, warm travelling suit, caught up two small bags, one holding her personal things, the other her jewels, and let herself out through her own private entrance into the darkness of the rear gardens. Where in the shadows the tall, blonde young engineer, Hugh Neils, was waiting for her.... * * * * * Negu Mah, when his beautiful wife had left the garden, sighed and put to one side his mug of molkai. "Sliss, my friend," he said to the Venusian, who was regarding him with large, unblinking pop-eyes, "I am troubled in my mind. Tonight I must dispense justice. Justice to myself and justice to another. To be just is often to be terribly cruel."
