Trivia Edit

  • The revolver Carlton uses at the end is a target variant of the Colt Peacemaker called the Bisley, named for the well-known shooting match in England where it made its debut. It is a fairly rare piece today.
  • This episode's narrative bears a number of similarities (a faked death, a hidden chamber where the "deceased" is holed-up) to the Sherlock Holmes story "The Adventure of The Norwood Builder".

Quotes Edit

Higgins: (Magnum is "playing" the saxophone) Magnum... Magnum!... Magnum!
Magnum: Hi, Higgins!
Higgins: How fiendishly deceptive of you, Magnum. I could have sworn I was hearing the emasculation of a large rodent. To my great surprise, I see the sounds are emanating from what I thought was a harmless musical instrument.
Magnum: Cute, Higgins, real cute.
(plays sax again)
Higgins: Why, Magnum? Why do this terrible thing?
Magnum: Higgins, I'll have you know I was very good. I was the second best sax player in my High School band.
Higgins: Well, how many sax players were there?
Magnum: Anyway, I just saw this in a pawn shop window and thought I'd like to try and get my chops back.
Higgins: May I suggest that your "chops" are irretrievable.
Magnum: Higgins, did you come here just to abuse me?
