The Cheat-Killer Returns

The man who wakes up in a drunkard's body has a son to deal with, and the son has been drawn into a card game that was fixed from the start. The boy is the son of the man whose body he now has. Before this he was the God of Gamblers, and he had stood at the top of the gambling world for most of his life. Then his wife was killed in front of him by an enemy from that world. He gave up gambling entirely after that, and the decision made him a threat to the people around him. A rival had him murdered. He came back in the body of a heavy drinker in a city in Southeast Asia. Although he had meant never to touch cards again, he sits down at the table to get the boy out and begins working against the people running the game.
