From publisher blurb:
A mysterious client offering a lot of money. A missing Russian noble. An ancient jade said to hold the spirit of the First Sovereign Emperor of China...
Through the sordid streets of 1936 Shanghai -- the Paris of the Orient -- the characters follow the footsteps of Count Rusikov, a refugee from the Bolshevik Revolution and archaeologist, to find the legendary Donguin Jade, a priceless artifact of Chinese history. But they are not alone -- Japanese agents, communist assassins, and provincial warlords stand between you and the prize!
