  • A professional boxer from 1940 to 1951 with an exceptional record, Sugar Ray Robinson held the world welterweight title from 1946 to 1951 and the world middleweight title in 1951, when he retired. He was inducted into the Boxing Hall of Fame in 1990, a year after his death.
  • Jimmy Doyle was a professional boxer from 1941 to his death in 1947. He was knocked unconscious in the 6th round of his fight with Sugar Ray Robinson for the world welterweight title, and was taken to a hospital, but never regained consciousness. He was 22.

Dustjackets: A Castle Wiki
  • CASTLE: Why am I narrating?
  • RYAN: Boy-o.
    CASTLE: Boy-o. Like a leprechaun.
    RYAN: Castle!
  • BECKETT: Did you just say Kate? Are you picturing yourself as the PI and me as the gangster's moll?
  • BECKETT: Why would you tell me a story if you don't know the ending?
    CASTLE: If you wanted a beginning, middle, and end, I have 27 novels you can choose from.
  • CASTLE: Beckett, I just realized something. "I Can't Give You Anything But Love."
    BECKETT: Excuse me?
  • MADDOX: Are you going to arrest us?
    BECKETT: Why would I do that? It sounded like self defense. Besides, we're looking for a woman named Vera, not Viola. And a PI named Joe, not a former bartender named Jerry.
  • VERA: Tell me you love me, Joe.
    JOE: Always.

Go here to discuss the spec
  • Ballistics go back to the 20s.
  • Joe and Vera stage her escape from Tom Dempsey during a fight between Sugar Ray Robinson and Jimmy Doyle; that fight was the fight that ultimately killed Doyle.
