Explorer Sheldon Lenox stole an idol carved from a giant ruby: Kila, the Hindu god of destruction. The Kila cult hunted him down and killed him, but not until after he'd sold the idol to a collector. The idol was then stolen from the collector, and Batman wnt to Mayor Wong in Chinatown to learn who might fence stolen goods. He was directed to Sin Fang who sicced giant Mongol warriors on Batman. Sin Fang turned out to be Lenox, who set up the whole thing to get the idol and escape the cult. He really died when Batman threw the Kila idol at him, and he fell out the window.
