What is the author's style in London Transports by Maeve Binchy?

Most of the twenty-two stories in Maeve Binchy's London Transports are told by impersonal third person narrators, all obviously female, and most omniscient. None seems inordinately prejudiced for or against their main characters, but in a few cases they describe events tongue-in-cheek. They deal with situations ranging from flaunting activities that are still considered taboo (e.g., abortion and wife-swapping), against a backdrop of a rather far-advanced sexual revolution.
