Stuff That Interests Me

A few years ago I wrote a script called Four Murders and Some Funerals, about an old lady who is the victim of a terrible miscarriage of justice. Seeking revenge she murders one of the perpetrators (by accident - long story, but it works), discovers she’s a natural at bumping people off, does away with the other three, and ends up becoming a vigilante serial killer - righting wrongs wherever she finds them and usually where the law has failed. I still think it was a pretty good script, though it never got made - a bit like Miss Marple, only more savage and retributionist. Anyway, as a result of writing said script, I had to come up with a number of original ways by which an old lady might kill people: I had one person pushed down a lift shaft, another electrocuted in the bath, another shot and another poisoned. This all involved quite a bit of research, especially the various poisons. Should our heroine use cyanide, polonium, fentanyl or botulinum, for example?For obvious reasons, I wasn’t quite comfortable
