I have reconsidered fresco's view after reading the book recently;spurred by Thea's review.
Camus had joined and then quit the Communist party while in Algeria. In post-war France he was dismayed by the imprisonments and executions of collaborators and the show trials conducted by Russian controlled Eastern block countries.
One of his characters,Tarrou says: "I have decided to reject everything that, directly or indirectly, makes people die or justifies others in making them die."
I think Camus was wrestling with his conscience and getting ready to break with his former comrades in the French Left.
