Book Reveiw: The Murder

I read The Muder. It was written by John Steinbeck (1902-1968). I thought that it's a little difficult for me to understand that story. Steinbeck as a greatest storyteller, a writer who can tell us many things about the human heart. It's about gender, love, marrage and violence.
Two main characters are Jim Moore and Jelka Sepic. They are a husband and wife. She is very beautiful and good at cook. She is perfect wife. But their love is sex and violence without conversation. They hardly talk each other. I don't like that love. On day, Jim killed the man who sleep with Jelka. He is her cousin. Jim was not arrested by police. I think she was loneliness.
