It was a BBC series and it screened in Australia somewhere around ’79-’82, so I don’t think it would have been made earlier than about 1977. The opening episode had a mother and daughter driving along a country lane in the UK (I have a vague recollection of drystone walls?) when a truck (or lorry, being British) carrying those big metal milk cannisters came around a corner too fast, and the load toppled on to their car. The mother was badly injured and the daughter had to stay somewhere (I think on a farm). The rest of the series was about a mystery the daughter was involved in while her mother recovered. The main image that stayed with me was obviously the milk cannisters falling, but I’d kind of like to know what the rest of the series was actually about!

The second one is a sci-fi novel I read during the mid-late ’80s. I’m pretty sure it was a recently published teen sci-fi one, and the only thing I can remember is that a teenager (must have been late teens) was sent undercover to infiltrate a rebellion and ended up swapping sides and (I think) being killed fighting for them. I’m reasonably sure it’s not Futuretrack 5, which I know I read in the same period, but I honestly can’t remember anything else other than the lead character’s mother crying that her son was too young, that of course he would be brainwashed into believing the other side’s cause. Pretty sure the rebellion was fighting for justice and equality against a ruling upper class (aren’t they all though!).

Tried Googling both of them, unfortunately I haven’t really come up with anything that’s ringing any bells. Hoping someone else will have an idea!
