My least favourite Camus book so far but to be fair, The Stranger and The Plague were very good. Still some good writing to enjoy here. The entire story is told through monologue, with the protagonist talking directly to the reader for the full length of the book. It's an examination of the protagonist's extreme narcissism, and the intense guilt he now feels for past actions.

Anyone who has considerably meditated on man, by profession or vocation, is led to feel nostalgia for the primates. They at least don’t have any ulterior motives.
I sometimes think of what future historians will say of us. A single sentence will suffice for modern man: he fornicated and read the papers. After that vigorous definition, the subject will be, if I may say so, exhausted.
Haven’t you noticed that our society is organized for this kind of liquidation? You have heard, of course, of those tiny fish in the rivers of Brazil that attack the unwary swimmer by thousands and with swift little nibbles clean him up in a few minutes, leaving only an immaculate skeleton? Well, that’s what their organization is. “Do you want a good clean life? Like everybody else?” You say yes, of course. How can one say no? “O.K. You’ll be cleaned up. Here’s a job, a family, and organized leisure activities.” And the little teeth attack the flesh, right down to the bone.
I had even developed a special loathing for speleologists, who had the nerve to fill the front page of our newspapers, and whose records nauseated me. Striving to reach elevation minus eight hundred at the risk of getting one’s head caught in a rocky funnel (a siphon, as those fools say!) seemed to me the exploit of perverted or traumatized characters. There was something criminal underlying it.
Have you noticed that death alone awakens our feelings? How we love the friends who have just left us? How we admire those of our teachers who have ceased to speak, their mouths filled with earth! Then the expression of admiration springs forth naturally, that admiration they were perhaps expecting from us all their lives.
On my own admission, I could live happily only on condition that all the individuals on earth, or the greatest possible number, were turned toward me, eternally in suspense, devoid of independent life and ready to answer my call at any moment, doomed in short to sterility until the day I should deign to favor them. In short, for me to live happily it was essential for the creatures I chose not to live at all. They must receive their life, sporadically, only at my bidding.
To be sure, you are not familiar with that dungeon cell that was called the little-ease in the Middle Ages. In general, one was forgotten there for life. That cell was distinguished from others by ingenious dimensions. It was not high enough to stand up in nor yet wide enough to lie down in. One had to take on an awkward manner and live on the diagonal; sleep was a collapse, and waking a squatting. Mon cher, there was genius—and I am weighing my words—in that so simple invention. Every day through the unchanging restriction that stiffened his body, the condemned man learned that he was guilty and that innocence consists in stretching joyously.
Thus the censor shouts aloud what he proscribes.
