We are just about still in the 1970s in terms of when this was recorded and transmitted but it is starting to feel very 80s. Bob Baker, sadly in a solo capacity for the first time, is doing a tremendous job of delivering us something new - daring to take on drugs as a topic on a tea time show with a relatively young audience is daring. A drug that makes people disinterested before ultimately leading to their death.

As it’s a Bob Baker script, there is a typically psychedelic edge to the way this is shot. K9’s voice has been tweaked and sounds a little more “traditional” in this one. More helpings of natural comedy and a fresh, loose feel to the production. Parts three and four unfortunately devolve into a runaround and the black capped baddie is about as bog standard as it gets but I do like the twist of the Dutch scientist Trist being revealed as the actual drug smuggler.
