Shortly after that, he found himself tempted by a young, gloomy couple, a Mr. and Mrs. Ridge, whom he visited one day looking for their young son, and found himself in the midst of a morbid quarrel. Mr. Ridge's incredible point of view was that this was too terrible a world to bring children into. Mr. Jell found himself on the verge of saying that he himself had personally visited forty-seven other worlds, and not one could hold a candle to this one. He resisted that, at last, but it was surprising how close he had come to talking, even over such a relatively small thing as that, and he had concluded that he was beginning to wear under the strain, when there came the day of the last temptation. Linda, the four-year-old, came down with a sickness. Mr. Jell learned with a shock that everyone on Earth believed her incurable. * * * * * He had no choice then. He knew that from the moment he heard of the illness, and he wondered why he had never until that moment anticipated this. There was, of course, nothing else he could do, much as he loved this Earth, and much as he knew little Linda would certainly have died in the natural order of things. All of that made no difference; it had finally come home to him that if a man is able to help his neighbors and does not, then he ends up something less than a man. He went out on the riverbank and thought about it all that afternoon, but he was only delaying the decision. He knew he could not go on living here or anywhere with the knowledge of the one small grave for which he would be forever responsible. He knew Linda would not begrudge him those few moments, that one afternoon more. He waited, watching the sun go down, and then he went back into the house and looked through the catalogue. He found the number of the serum and dialed for it. The serum appeared within less than a minute. He took it out of the Box and stared at it, the thought of the life it would bring to Linda driving all despair out of his mind. It was a universal serum; it would protect her from all disease for the rest of her life. _They_ would be coming for him soon, but he knew it would take them a while to get here, perhaps even a full day. He did not bother to run. He was much to old to run and hide. He sat for a while thinking of how to get the serum to her, but that was no problem. Her parents would give her anything she asked now, and he made up some candy, injecting the serum microscopically into the chunks of chocolate, and then suddenly had a wondrous idea. He put the chunks into the Box and went on duplicating candy until he had several boxes. When he was finished with that, he went visiting all the houses of all the good people he knew, leaving candy for them and their children. He knew he should not do that, but, he thought, it couldn't really do much harm, could it? Just those few lives altered, out of an entire world?
