For some reason, the title sequence from series 3 is used for this episode (although it features the music from the current series.) This means that Inspector Galloway appears in the titles even though he is no longer in the series.
This is the first episode not to feature P.C. Taffy Edwards (Colin Blumenau).
The making of this episode is detailed in the book "Witness Statements: Making The Bill (1988)" featuring memories from the production team, production notes, locations and more.
