"Can you give us a summary?" "Sure." Dan told him briefly what had happened. Kielgaard was silent a moment. Then he said, "What do you think 'charge' is?" "I haven't been in any condition to think. Maybe it's a surgically implanted battery, set to run down after so long." "Too clumsy. What about radioactivity?" "H'm. Yes, you mentioned a mine on the inner planet. Maybe they mine radioactive ore. That would explain why I have some charge. There's residual radioactivity even in the atmosphere of Earth." "That's so," said Kielgaard. "But not every planet has it. I'm wondering about this other agent you mentioned seeing. He sounds to me like someone from Trans-Space. And that's bad." "They play dirty," Dan conceded. "Worse than that," said Kielgaard's tiny voice. "They recruit their agents from Lassen Two. Maybe that's a break. Unlike Earth, Lassen Two is nearly radiation-free. And Trans-Space doesn't use finesse. They'll pump Porcys full of agents loaded down with organo-transmitters. Visual, auditory and olfactory. They'll broadcast on every wave-length, suck out as much information in as short a time as they can, then either pull some dirty trick or slam the Porcyns an offer. That is, if everything goes according to plan. "But meanwhile," he added, "one or more of their agents is bound to stand in front of a free 'Your charge' device somewhere in the city. Very likely, that agent will be radiation-free and some Porcyn, for the first time in his life, is going to see a bulb that doesn't even
