What is the passage about?

Jonathan Rivers lived alone in a neat, two-storey, semi-detached house in Compton Street. Like many bachelors approaching middle age, he was getting rather stable in his ways. He caught the same train to London each morning, ate his lunch in the same crowded restaurant near the office where he worked and always came home on the 6:00 train. People were so used to seeing Jonathan set off at a quarter past eight, dressed in a simple dark suit, wearing a black bowler hat and carrying a rolled umbrella on his arm, and they said you didn’t need to wear a watch if you lived in Compton Street.
     Ever since Jonathan had set up house in Compton Street, he had looked after it very care fully. He worked hard in the garden every weekend and set out to impress the neighbours with his flower beds and lawn. Before he left the house in the morning, he carefully closed all the doors downstairs, opened some windows to let the air in and locked the front door. Everything Jonathan did was tidy and systematic.
