World's End by Richard Jefferies

His heir! Sternhold seriously believed that he had no living relations. It is often said that poor people have plenty of children, while the rich, to whom they would be welcome, have few or none. This was certainly a case in point. The poor Baskettes, who had been shipped to America, had a whole tribe of descendants. Here was a man who, nominally at least, was the largest owner of property known, who was childless, and had already reached and exceeded the allotted age of man.

Sternhold was seventy-two. He looked back and ransacked his memory. He had never heard anything of this uncle, his father's brother; his mother's friends were all dead. There was not a soul for whom he cared a snap of his fingers. Firstly, he had no relations; secondly, he had no friends, for Sternhold, wide as was his circle of acquaintances, had never been known to visit anyone. His life had been solitary and self-absorbed.
