What is the author's style in The Remains of the Day by Kazuo Ishiguro?

For the most part, the style of The Remains of the Day flows from the voice of Stevens, whose memories provide the novel's text. The entire book is his account of the past and present, which gives the reader a distinct impression of his character. Stevens's style is formal, courteous, and longwinded. He has a tendency to be very precise in his communication, to overthink matters, and to share his every thought. For example, rather than simply explaining that Mr. Farraday's banter makes him uncomfortable, Stevens rambles on with reasons why he is unable to engage with his employer in this way, with what he imagines Mr. Farraday thinks of him, and with his judgment that his inability to banter is a failing of his duties. He returns to this concern repeatedly.
