Alice's show, which preaches that crime doesn't pay, is a version of the show Jack could have taken on the road himself. Alice is still trying to atone for her husband's sins. Still, she does not lead a spotless life. Marcus suggests that the restaurant Alice intended to open before her murder surely would have turned into a speakeasy, which suggests that Alice maintained a few of her husband's underworld connections. Alice also manages to collect the kickbacks, probably by threatening the unions. This threatening is perhaps what led to her violent death.
The final line of the book is an almost exact restatement of Marcus's declaration at the beginning of the novel: Jack is not dead. These identical statements frame the life of a man who still has a hold on the American imagination. As long as the legend of Legs Diamond survives, in some way, he will live. Marcus has used this statement as a touchstone for seeking out all of the many ways in which Jack Diamond lived, before and after his death. The final chapter is a brief, cerebral scene in which Jack seems to be carried off to heaven or hell. Marcus makes reference Jack's next life, suggesting that Jack has a chance at reincarnation. Perhaps what Marcus implies is that Jack's reincarnation has taken place in the form of the life he lives in this book.
