Does anyone happen to know where a character would be able to find some kind of poison in or around a school? Preferably something like cyanide, if that would be at all plausible. When I wrote the scene originally, I didn't bother to explain what the poison was or where it came from, only that it had been located somewhere on campus. I imagined that it, whatever 'it' was, had come from the science labs or from the groundskeeper's pesticides or something. It didn't really matter to the story, as nobody consumes the poison in the end anyway... But I've realised that I ought to at least give a passing mention as to what it was. I've had a look around on google for ideas and found loads of information on various poisons and their effects, just not enough on where the poisons can actually be found. Yet. If anyone has any suggestions, they would be greatly appreciated.
