"They're classified as human," snapped Grant. "And a lot of them are more human than the pure-white Terran. Spinach, I call it. Anyway, there is a simple explanation for all this and when it is uncovered, all of your rantings and ravings will go to pieces like a bit of charred paper. Call it telepathy if you want--I'm not discounting though I'm skeptical--but I don't feel any warnings yet." Jenna sat down, closed her eyes, and composed her body into a relaxed pose. She said nothing. Lindsay noted, and said: "Keep it coming, Grant." "Well," said Grant, "we're at the critical hundred feet, Ears and I. Come here, mutt! That thing is dangerous! Dog doesn't care, folks. Y'know, there's nothing like having a mutt around to teach you faith. Jenna?" She opened her eyes. "Yes?" "I'm going in! You're Martian and you're sensitive. Maybe you can catch the backwash if there's any mental shenanigans." "I'll try." "Believe it now?" called Lindsay. "Not entirely. But I'm not missing any bets. Now, I am taking my little hatchet in one hand and I'm going out to ... _Jenna! You--!_" The storm burst, the sky flared bright, and the waves of sheer energy beat the ship, stormed in through the windows and the radiation counter shrilled madly. The pillar of fire mounted like a rolling cloud, reaching for the sun. "Grant," said Lindsay with a dry throat. Jenna sobbed. "What did he mean?" demanded Lindsay. Jenna shook away her tears, swallowed deeply. "I know," she said. "I know." "You--?" "I caught it," she said. "Then it was you," he snapped harshly. "Tell me, Jenna, what kind of enticement did you use to get him going?" "You fool," she snarled at him. "Blind, stupid fool." She stood up, blazing. "Yes," she said. "I've taken all you gave me, and took it gladly, happily. And I hoped that I could make up to you for ... for ... causing your loss. Yet you've never forgotten that I'm Martian, and that if you'd married a Terran you could have the plaudits and the admiration due any fighting officer. That's rankled in your soul until you hate me!" she screamed. "And what could I do? I'd have made it up to you," she said, her voice quieting, "but I didn't know how. And now you think I'm responsible. Well," she said accusingly, "how do I know but that you are planning revenge on Terra for being blind." "Jenna, you--" "Well, I do know. And if you think that I'm--" "What do you want me to think?" he asked her. "What were Grant's last words?" "He--" "Accused you!" Jenna turned quietly. She stopped at the door. "I solved one fuse because I thought Martian," she said quietly. "I'll solve the next one for you! You've wanted to be free to join the Corps in space. Then follow me close, because when I solve this one there will be no question." "Jenna--what is it?" "It is the fuse itself," she said. "A rudimentary brain that reacts upon receiving any thought of removal when that thought originates within a hundred feet or so." "Utterly fantastic!"
