"THE PEARL"

I have been reading the novel "THE PEARL" for almost one week but still, I'm not yet half way.....
I'm still in the part wherein Kino decides to sell the pearl but he felt the someone has been cheating on him.....He knew of the 3 men who were tracking him to get the pearl from him and because of this he got mad like a machine and ambushes and killed the 3 men.
