A Death in the House by Clifford D. Simak

A Death in the House (Galaxy, October 1959) by Clifford D. Simak starts with a farmer called Old Mose looking for his cows but discovering an injured alien:

It was a horrid-looking thing, green and shiny, with some purple spots on it, and it was repulsive even twenty feet away. And it stank.
It had crawled, or tried to crawl, into a clump of hazel brush, but hadn’t made it. The head part was in the brush and the rest lay out there naked in the open. Every now and then the parts that seemed to be arms and hands clawed feebly at the ground, trying to force itself deeper in the brush, but it was too weak; it never moved an inch.
It was groaning, too, but not too loud—just the kind of keening sound a lonesome wind might make around a wide, deep eave. But there was more in it than just the sound of winter wind; there was a frightened, desperate note that made the hair stand up on Old Mose’s nape.
Old Mose stood there for quite a spell, making up his mind what he ought to do about it, and a while longer after that working up his courage, although most folks offhand would have said that he had plenty. But this was the sort of situation that took more than just ordinary screwed-up courage. It took a lot of foolhardiness.
But this was a wild, hurt thing and he couldn’t leave it there, so he walked up to it and knelt down, and it was pretty hard to look at, though there was a sort of fascination in its repulsiveness that was hard to figure out—as if it were so horrible that it dragged one to it. And it stank in a way that no one had ever smelled before.  p. 134-135 (The Year’s Best SF #5, edited by Judith Merril, 1961)

Eventually Mose manages to free the creature and takes it back to his farm (and his less than salubrious surroundings—we learn later that he is a widower, and has also lost his dog to old age). After putting the creature in front of the fire he phones the local doctor, who attends, but cannot do anything for the creature. Mose pays him with a silver dollar (this will be significant later) and meantime goes out into the woods to recover the alien’s damaged ship, a bird cage-like machine.
When Mose wakes up the next day the alien has died—and the story becomes an different piece entirely, one which begins with him attempting to get a plot in the town cemetery so he can give the creature a decent burial. He is unsuccessful, and then also fails to get the parson to come out to the farm to perform a service when he decides to bury the alien on his land. When Mose prepares the body for burial he finds a cloudy glass sphere in a pocket-sized slit in the alien’s body, which he subsequently replaces.
Various visitors turn up at the farm in the days that follow: the local sheriff, a professor from the nearby university, and a flying saucer nut—but Mose has already ploughed over the grave to hide it, and bluntly tells them he will not reveal the location.
The final leg of the story (spoiler) sees an odd plant start to grow on the site of the burial plot and eventually form a recognisable shape. One morning Mose wakes up to see the clone or descendant of the alien at his door. As Mose’s loneliness has been established throughout the tale, he is delighted to see the creature—but then it sees the bird cage machine in the barn and indicates to Mose that it wants it repaired. Mose is conflicted by this as he realises that he will not only lose the alien’s company but will also have to sacrifice all the silver dollars he has hidden away—his entire savings—to make an internal part to repair the machine.
After the ship is repaired, and just before the alien gets in its machine and vanishes, it gives Mose the small glass sphere that he previously found on the body—but this time it is clear and not cloudy. It makes Mose feel happier, and gives him a sense of companionship.
The final paragraph of the story then switches to the alien’s point of view and, as well as bootstrapping the quality of this piece up another notch, partly reframes what has come before:

It was dark and lonely and unending in the depths of space with no Companion. It might be long before another was obtainable.
It perhaps was a foolish thing to do, but the old creature had been such a kind savage, so fumbling and so pitiful and eager to help. And one who travels far and fast must likewise travel light. There had been nothing else to give.  p. 154 (The Year’s Best SF #5, edited by Judith Merril, 1961)

This story, with its principled, compassionate and very human main character, is a lovely piece, and a surprisingly affecting one too. Certainly one for a ‘Best of Clifford Simak’ volume, and a no-brainer for a ‘Best of the Year’ anthology as well.
