Nitpick: the timeline in this episode with respect to the others in the series is a bit off as Nicholas Cain mentions that he sent Norma Sherman to jail on a narcotics rap over two years before the episode takes place. Thus, it appears that Cain has been on his crusade against organized crime a bit longer than in conjunction with the remaining episodes in the series.
Troy: Nick, what do you got against me?
Cain: Arthur, you know what I've got against you. It's just that I can't pin anything on you.
Norma (about her drug habit): I've kicked it.
Joe: You've kicked it before.
Cain (about the Mob): When those boys yell mush all the dogs pull their weight.
Norma: Was I magnificent or merely great?
Cain: You were greatly magnificent.
Jethrow: Can I call my lawyer or is the law in this state different than the rest of the country?
Norma (about Maury): Go easy with him, Nick. He's just a poor, helpless slob like I was.
Edward Asner would go onto star in The Mary Tyler Moore Show and Lou Grant as well as set a record for most Emmys won by an actor.
This marks the only episode where Cain shoots and kills someone.
Dorothy Dandridge sings The Man I Love, Takin' a Chance on Love and As Long as I Have You.
Alternate episode title: Blues for a Junkman--Arthur Troy.
Additional material was shot, and this episode was then edited into a movie, The Murder Men, for theatrical release in 1962.
