The problem as I see it is in the fact that the book describes the world very naturalistically. The first half of the book is basically Proust, if Proust were less introspective and didn't care to inflate his word count. It's actually rare to find a book where the events of day-to-day life -- running to catch a tram, or spending a lazy Sunday afternoon on one's balcony -- are relayed with such clarity and directness.

Then the murder happens -- which was a highly contrived and even quite ridiculous scenario, in that (a) Mersault's party was quite literally being stalked by an armed gang, (b) Mersault separated himself from the pack and was menaced by one of his stalkers, who was armed with a knife, (c) the naked knife was in the man's hand, as that man was blocking Mersault's path, (d) there were no witnesses, and (e) Mersault was a Frenchman in colonial French Algeria.

Not 1 in 10000 times does that go to court for murder, and not 1 in 1000000 times does it result in the death penalty.

But, anyway, back to my point: The minute the murder happens, we're yanked out of the naturalistic world and thrust directly into the world of Kafka's The Trial. Nothing makes sense any longer. What once was so true-to-life becomes something akin to the hallucinatory descent of divine justice -- a bad trip, a fever dream. "Yeah, you're off to the guillotine because you didn't cry at your mom's funeral. What kind of monster are you?" The most parsimonious interpretation is that the narrator has simply lost his mind.

Don't even get me started on the fact that every reviewer thinks that Mersault was executed, when that never actually happens in the book, and would result in him not being able to write the book in the first place. (Further confused by the variety of tenses used in the construction of the prose.) The book, which is written something like a memoir, ends with his appeal still pending, and the prison chaplain "sure of its success."

As to the critiques, the Orientalist one is in Edward Said's "Culture and Imperialism" but I don't think that the full version is online. As I recall, it basically concerned point (e) above, and noted that the trial would not have happened -- so the notion of the trial may be a sort of cope.
