Ricky nodded puzzledly. "Yes, that's the principle. But how is that going to help us?" "The Vestans," Kenniston reminded, "seize control of their victims by inserting those tiny needle antennae of theirs into the victim's nerve-system to establish contact. Wouldn't your formula insulate the nerves against such contact? Wouldn't it make a man immune to Vestan attack?" "Why, it would!" Ricky declared wonderingly. "I never thought of it, yet it's entirely logical." "Then," Kenniston said swiftly, "I want you to give every one of us, including yourself, an injection of the formula right now." The driving purpose in his voice brushed aside all their bewildered questions and objections. Hastily, Ricky prepared his hypodermics and rapidly made an injection of the milky fluid into the big nerve-centers in the neck of each of them. Kenniston did the same for Ricky himself. "We should be immune now to Vestan attack," Kenniston said prayerfully. "But what good's that going to do us?" Holk Or demanded. "Are you figuring to try an escape into the jungle?" "No, I'm figuring on taking the Falcon—by using the Vestans," Kenniston replied. "Holk, can you get into the ship and turn off the power that keeps the electric wall going? Can you drop the wall?" The Jovian's jaw dropped. "Why, sure, I could do that, but if I did, all those hordes of Vestans outside the wall will burst in here—" He stopped, his eyes bulging. "Good God, then that's your plan? To let the Vestans in?" "That's it," Kenniston said tightly, his face grim. "To let the Vestans in on the pirates. That'll give us a chance to take the ship—if the formula really makes us immune to the Vestans." The terrible nature of the proposal stunned them all. But in a moment a flame of purpose lit in the Jovian's eyes. "I'll do it!" he swore. "It's better than waiting for Dark to kill me like he's planning. You be ready!" The Jovian slipped out of the opening in the back of the hut. They saw him presently, casually approaching the door of the Falcon. John Dark stood, a tall, dominant figure in the moonslight, barking orders to the scores of pirates who were
