"The mess sergeant had a trick knee when he came here. The trouble disappeared completely when we arrived. One of the geologists had an ulcer. Hasn't felt a pain since the second day. Another guy had some bad powder burns from a lab experiment that disappeared over night, just like your burn did. "When we first suspected what was going on, we asked the crew at Silver Spring to send up white rats, guinea pigs, and dogs, with everything from cancer and T.B. through rabies to polio, and the results were one hundred per cent perfect, with complete recovery in every case inside of a week. _And_, this is important, they stayed cured when sent back to Earth." Yogi's eyes were burning like one of them gospel preachers at a revival, and his voice was shaking. I was catching the excitement myself. The Captain took over the story. "I suppose you're wondering what we want of you?" "I sure am. This is a big deal, isn't it?" I looked at the little scar on my hand again, to convince myself nobody was kidding. "Here's our problem, and our plan, Tuck. Yogi told me what you said about the taxpayers' right to know where their money is going, and it ties in with what a lot of us up here have been discussing. "Most of our fellows are like Yogi--technicians who chose their line of work because they thought they could help make the world a better place to live in. Now that they have the chance to make the biggest contribution of their whole lives, they're all hemmed in by military rigamarole and red tape. It goes against the grain for scientists." "You mean the Army is keeping the place top secret, so it can't be used for a ... well, a health resort?" The Captain nodded. "I'm not arguing with the military reasons for security. Maybe they're right on that score. But in the meantime, thousands of people are dying every day of disease, needlessly, while the Army keeps the secret that could end those deaths. The people will find out about it eventually, and I don't think they'll like it. Suppose your mother were to die of cancer a few months from now, and you were to find out later that her death was unnecessary, and that your own government could have stopped it. What would you think? How about it, Peters, are you with us? What do you say?" * * * * * The Captain had been talking louder and faster till he was practically out of breath. "I got just one thing to say, Captain. My baby sister died of T.B. just before her eighteenth birthday last year. You can bet your bottom nickel I'm with you on this deal, right down the line. Just give me the scoop. I'll go along." Yogi and the CO slapped me on the back. They explained to me, Mr. President, all about this secret Congressional hearing to be held on the Lunette project next week, and how I should go to Washington and get my Congressman to spring me as a surprise witness--a civilian who had been to Lunette and knew the score.
