"Boys, Riley was wrong. He believed what he said, all right, but Smith and I know better. Don't worry about devils. These're just some dirty, skulking dogs who got away with murder this time but who won't do it again. We know where they're hiding. I'm checking up on them right now. After that you'll all get a chance to square accounts for poor old Riley!" * * * * * "But the casting!" Smithy protested when he and Rawson were alone. "You can't explain that disappearance so easy, Dean." "No, I can't explain that," Rawson's words came slowly. "They've got something that we don't understand as yet--but I'm going to know the answer, and I'm going to find out to-night!" He was seated behind the wheel of his old car. "I'm as good a desert man as there is in this crowd," he told Smith. "And it's my fight, you know. I'm going alone. But there'll be no fighting this trip; I'll just be scouting around." He leaned from the car to grip Smithy's shoulder with a hand firm and steady. "You didn't see the crater when the show was on. You think that I'm crazy to believe it, but up in that crater is where I'll find the answer to a lot of questions. Lord knows what that answer will be. I've quit trying to guess. I'm just going up there to find out." He was gone, the rear wheels of the car throwing a spray of sand as he started heedless of Smithy's protests against the plan. Rawson was in no mood to argue. He must climb the mountain while it was night; under the sun he would never reach the top alive. He would go alone and unseen. He swung wide of the deserted town at the mountain's base. The spectral walls of Little Rhyolite still showed their empty windows that stared like dead eyes, and the man guided his car without lights along a hidden stretch of hard, salt-crusted desert. He felt certain that other eyes were watching. * * * * * He began his climb at a point five miles away. The slopes that seemed smooth and hard from a distance became, at closer range, a place of wind-heaped, sandy ash, carved and scoured into fantastic forms. But its very roughness offered protection, and Rawson fought the dragging sand, and the gray, choking ash that dried his throat and cut it like emery, without fear of being observed. He fought against time, too. Above Little Rhyolite, whatever mysterious men were making the ascent would find the going easy. There were windswept areas, long fields of pumice; a man could make good time there. Rawson had none of these to aid him. He cast anxious glances toward the eastern sky as he struggled on, till he saw gray light change to rose and gold--but he stood in the titanic cleft in the crater's rim as the first straight rays of the sun struck across.
