Episode Juliet Bravo: Chasing the Dragon (1985) was widely criticised by the media and politicians after it was first shown in 1985. The story centres around a schoolgirl who had become a heroin addict. It was felt that too much detail was shown of the ways in which heroin can be administered and that this might encourage school children to copy what they had seen.
The signature tune used was arranged by Derek Goom using motifs and key changes from 'Prelude No. 2 in C Minor' from 'The Well-Tempered Clavier' Book 1 by J S Bach.
