Tai-Pan, Noble House and Gai-Jin are all about the Struan Clan in different time periods

A descendent from one of the main characters in Shogun appears in Noble House, the main character and the authors alter ego in Rat King appears in Noble House, too. And one of the side characters in Noble House as a prominent role in Whirlwind.

I really hoped they would give Clavells whole Asian Saga the treatment they gave Shogun. But it looks like they are just doing another season with no connections to the books.
