T Singer begins with thirty-four-year-old Singer graduating from library school and traveling by train from Oslo to the small town of Notodden, located in the mountainous Telemark region of Norway. There he plans to begin a deliberately anonymous life as a librarian. But Singer unexpectedly falls in love with the ceramicist Merete Saethre, who has a young daughter from a previous relationship. After a few years together, the couple is on the verge of separating, when a car accident prompts a dramatic change in Singer's life.
The narrator of the novel specifically states that this is not a happy story, yet, as in all of Dag Solstad's works, the prose is marked by an unforgettable combination of humor and darkness. Overall, T Singer marks a departure more explicitly existential than any of Solstad's previous works.
