Starring: Dennis Waterman, James Bolam, Amanda Redman, Alun Armstrong
Season Final - S1-E6
Factual error: Mobile phone signals cannot pass through steel very well if at all, so the recording of the mobile phone conversation given to the head of UCOS should be breaking up in places, or the call should have been cut off when the door was closed - it shouldn't be crystal clear.
Revealing mistake: On both occasions when Sandra is sitting in the boat going out on the lake to dive actress Amanda Redman has obviously been replaced by a stunt double.
Gerry Standing: Will you stop creeping up on me.
Brian Lane: I don't creep, I glide.
