I am new here so I hope this is the right place to ask this! I'm not a writer by any means, but I am trying to write a little murder mystery for a group of my friends.
The idea is that the victim will be killed by some kind of poison that was on the tip of a needle attached the their reading glasses. The needle will prick them in the eye when they put the glasses on. They will obviously be aware that they've been pricked in the eye, so it needs to be a fairly fast acting poison that kills them before they realize whats happened. The poison also would ideally not show up in an autopsy.
I know it's a bit far fetched that they wouldn't see the needle on their glasses, but I'm leaning on the fact that they are extremely nearsighted and the needle is very small. Being that it's just a little game for my friends, I'm okay with a bit of a stretch.
Is there any chance that there is a poison that would kill in this way? I've done some google searching but haven't been able to find much.
Thanks in advance!
