He remembered that Scudder had been talking with the contractor when Hennesy left to get the sheriff. He knew already that Scudder had opium, for the use of Tom Lee. It would have been no hard matter for Scudder to have planted some of the drug among his own effects, he reflected. "I'll settle with you, Scudder!" he vowed to himself. Toward sunset they searched the horizon, but vainly. What was happening beyond that horizon, over the rim of the world? Murray worried, more about his friends than himself, for he was little concerned over Scudder's enmity and attempts to disprove him in the eyes of Tom Lee. But Sandy Mackintavers was in the toils, and as for Bill Hobbs--Murray groaned at the thought. He knew that Willyum had only recently come out of "stir" when he had picked up the ex-burglar. Now that Bill Hobbs had deliberately sacrificed himself in order to save Murray and Claire Lee, it meant a setback that would put him in the criminal ranks again for good. And at this moment, when both his friends needed him so sorely, Murray was stretched out here in the desert, helpless and impotent--himself under the menace of a cloud! During that day, Murray and the girl lived long, came to know each other deeply; not with the superficial words and phrases and acts of civilized life, but in primitive ways and fashions. When the night closed down again like a mantle above the desert, it drew them yet closer together. "Your father will be here tomorrow at latest," said Murray reflectively. "He should have come long ago." Claire's eyes were filled with somber shadows. "I'm afraid that--that Doctor Scudder has been keeping him under the influence of opium. How I detest and fear that man! I wish that Father could be made to see him as I see him, that he would break with the man!" "I think he will, eventually," said Murray, and smiled grimly to himself at thought of the reckoning he would have with Scudder. The night passed. Once, Murray wakened; it seemed to him that he caught, in the desert silence and cold stillness, the throbbing motor of an automobile. Yet he could see no lights, and Claire had not wakened. He lay for a space, watching vainly, and at last fell asleep again. With the morning, Murray opened his eyes to find Claire already up and breakfast nearly ready. He tried to rise, and managed to leave his blankets, but he was giddy and too weak to walk. With a muttered curse at his own feebleness, he sank down again upon the sand. "If no one shows up here by afternoon," he declared resolutely, while they breakfasted and discussed the situation, "I think we'd better make an effort to get back with the car. She may run; when it comes to flivvers, the days of miracles are by no means over----" At this instant, Claire sprang to her feet with a cry of joy. "Look--look! A car!"
