Interesting psychology in use in this episode.  First the wife who isn't happy after 20 years of marriage and wondering if she married the wrong man.  Second the gangster who never let go of the one piece of evidence that could put him away for life.  Lastly the wife's husband who has been trying to put the gangster (a childhood friend) away since the murder of their parish priest.  A pretty good listen for me even if a bit predictable.
