"There's a gang, the 49ers.  Their Chinese name is the Sze Kaus.  One of their crew has decided that my busting of their group a few months back for illegal BTL manufacture warrants a death sentence for those connected to me.  Not me, those<em>around</em>me.  That can't stand."  The dwarf took a drink.  "I want you to find the head of the Sze Kaus - they refer to him as a 438.  Find him, and make him give up the identity of the person threatening me.  If he won't, put the fear of God into the gang."  Translation - kill the boss.
