Beyond the City — Arthur Conan Doyle

From Beyond the City: "How deeply are our destinies influenced by the most trifling causes! Had the unknown builder who erected and owned these new villas contented himself by simply building each within its own grounds, it is probable that these three small groups of people would have remained hardly conscious of each other's existence. But there was a common link to bind them together. And especially to the Admiral and the Doctor were this closer intimacy and companionship of value. Each had a void in his life, as every man must have who with unexhausted strength steps out of the great race, but each by his society might help to fill up that of his neighbor."
