The Queen of Spades was third in command of the 52 Gang. Like the rest of the gang, she was typically depicted wearing a hood that concealed her features.
Queen of Spades had a romantic relationship with 10 of Spades, whom Dick Tracy was impersonating, which enabled Tracy to gain her confidence and tie her up. She took over leadership of the gang when Ace of Spades was captured and King of Spades was killed.
Queen of Spades eventually staged a last stand where she and the rest of the gang were killed.
