The opening notes of the theme music spell "Morse" in Morse code, slightly altered for musical purposes. The same notes are also included at the end and in places within the theme music. It has been alleged that the theme sometimes spells the name of the murderer or, as a red herring, an innocent character, and that even the composer has stated this. However, there is nothing documented on the Internet for any specific name or episode. Morse code experts say that, aside from the code for "Morse", any other Morse code-like notes in the theme are gibberish.
