At the moment, however, Tommy was only concerned with saving Dodd from the madman. He got his foot beneath the shell, then inserted his leg; using his whole body as a lever, he succeeded in turning Bram over on his back. Then, and only then, the swarm rushed in upon them. Then Tommy realized that he had touched one of the triggers that regulated the beetle's automatism. In another instant Bram would have been torn to pieces. The needle-beaks were darting through the air, the hideous jaws were snapping. Bram's yells rang through the cavern. * * * * * Dodging beneath the avalanche of the monsters, Tommy got Bram upon his feet again. The beetles stopped, every movement arrested. Bram's hand went to the pocket of his tattered coat, there came a snap, a flash. Bram had ignited an automatic cigarette-lighter! Instantly the monsters went scurrying away into the distance. And Tommy had another clue. The beetles, living in the dimness of the underworld, could not stand light or fire! He ran to where Jimmy was lying, face upward, on the ground. His face was badly scarred by Bram's nails, and the blood was spurting from a long gash in his throat, made by the sharp flint that was lying beside him. He had some time before discarded his fur coat. Now he pulled off his coat, and, tearing off the tail of his shirt, he made a pad and a bandage, with which he attempted to staunch the blood and bind the wound. It must have taken ten minutes before the failing heart force enabled him to get the bleeding under control. Dodd had nearly bled to death, his face was drawn and waxen, but, because the pulsation was so feeble, the artery had ceased to spurt. Then only did Tommy take notice of Bram. He had been squatting near, and Tommy realized that he had unconsciously observed Bram put some sort of pellets into his mouth. Now he realized that Bram was a drug fiend. That was what had made him walk out of the Greystoke camp in the storm. Bram got up and came toward them. "Is he dead?" he whispered hoarsely. "I--I lost my temper. You two--I don't intend to kill you. There--there's room for the three of us. I've got--plans of the utmost importance to humanity." "I don't think much of the way you've started to carry them out," answered Tommy bitterly. "No, he's not dead yet, but I wouldn't give much for his chances, even in the best hospital. The best thing you can do now is to go to hell, and take your beetles with you," he added. * * * * * Bram, without replying, raised his head and emitted from his throat the shrillest whistle that Tommy had ever heard. The response was amazing. Rasping out of the darkness came eight beetles in pairs. Instead of leaping from an upright position, they trotted in the manner of horses, on all fours, their shells, which touched at the edges, forming a solid surface, gently rounded in the center so that a man's body could lie there and fit snugly into the groove.
