Who is Gorth Brock from Tai-Pan and what is their importance?

Gorth is the son of Tyler Brock. He is a vile and sadistic man who likes to beat up prostitutes. He cultivates Culum's friendship as a way of causing trouble for Dirk and sets Culum up with a poxed woman in Macao. After attacking Dirk at the Club, he is challenged to a duel but is killed by three Chinese before the duel can take place. May-may had requested that Gorth be killed through Gordon Chen, and Gorth is killed in Macao, right before he is to duel Dirk.
