What style is Albert Camus' The Stranger written in?

Albert Camus' story, The Stranger,
was originally written in French, in the narrative style, in the first person. It is
considered a "psychological self-examination," however Camus' work had a twist: the
protagonist in the story does not provide a detailed description for the reader, leading
him or her to the conclusions that writer has in mind, but rather presents the main
character's "action and behavior" and lets the reader make his or her own
judgments.

The primary reason for this is that Camus
believed:

...psychology is action, not thinking about
oneself.

The speaker leaves
too many things up in the air because he has not explained everything in the narrative.
Rather than "spoon-feeding" the reader with "commentary," Camus describes what the
character is "thinking and perceiving," but the only influence the author provides to
the reader is writing that reflects the attitude of
Meursault—frustrating (to the reader)
indifference, almost to the point that one wants to shake either
Merusault or Camus or both. These gaps in the story by way of Merusault's behavior (or
lack thereof), along with the half-informed opinions of those who testify at the trial,
seal Meursault's fate.
