The mysterious caller as he's (almost) seen in "The Dark Side of the Mook".

The mysterious caller is a person who makes several phone calls to Det. Sam Tyler during the series. His face is never shown (however it is revealed who he is towards the end of the series) and he always disguises his voice with a voice changer.

Trivia[edit | edit source]

  • This parallels the Hyde calls DI Sam Tyler receives in Manchester.
