The detail from the story that helps emphasize the abnormality of the city is that Mrs. Drover was watched by "no human eye".
In "The Demon Lover," a short story by Elizabeth Bowen, the author retells a well-known folktale. Something abnormal is something not ordinary. In the opening paragraph, Bowen starts to arouse unease right away. Mrs. Drover writes "an unfamiliar queerness had silted up; a cat wove itself in and out of railings, but no human eye watched Mrs. Drover's return" as she approaches her London home.
The author decided to state that no human was watching Mrs. Drover rather than simply stating that nothing was, which tells how abnormal the city was.
