Stranger #1

Old Salamano is Mersault's grumpy old neighbor that likes to swear at his dog.  Both he and the dog have gross skin conditions.  Salamano beats and swears at his dog, but he still misses it when it runs away.  He used the dog to fill the hole his wife left behind when she passed, and I think Camus is using Salamano and the dog to say something about relationships.  Salamano hates and at the same time loves his dog, and the dog seems to forget that he gets beaten and yelled at so often.  So... one's love for another can blind them to all the bad stuff that's in a relationship?

Raymond is also Mersault's neighbor and he also beats things inside his apartment.  This time, instead of a dog, it's a woman.  He lives in a one-room apartment that is crudely decorated with pictures of naked women.  He also has an angel above his bed, which I find interesting.  Raymond is a pimp (sorry, don't know what else to call it) who gets enjoyment out of going to whorehouses and beating his girlfriend.  In his defense, she did cheat on him, but violence is never the answer, my friends.  However, it might have been the norm in 1942 so maybe it was the answer to beat your ladies back then.  Mersault and Raymond have a "manly" relationship.  They connected on a level and became pals, and Raymond seems to think Mersault gets him and wants to talk to him because he's a man! Camus is using Raymond and his relationship with Mersault to say something about men, and also women.  Seeing as Raymond's interactions with Mersault are quite different from those with his lady friends, I would think that Camus is contrasting men and women. 

Marie used to work with Mersault and is his love interest throughout the novel.  We see their romance in part one of the book, while in part two she doesn't appear save for Mersault's trial and when she visits him in jail.  While he is in jail, Mersault continues to think about her even though their relationship has deteriorated.  Her appearance isn't really described, except for that Mersault thinks she's beautiful.  She is a cheerful person from what I gathered.  She jumps up and down because of the weather and pokes fun at Mersault quite often.  Camus uses Marie to bring out some of Mersault's slightly off-kilter views on things like love.  Mersault narrates the story, and when thinking of Marie he often describes her body.  Camus is using Mersault's thoughts about Marie's body to sort of objectify women.
