Alright, then how can it be proved that there was a potassium overdose? Telltale signs beyond the tiny wound?

Just being the 'devil's advocate' here. Because you know someone reading a book will call the author out on details like this.

An example: I am reading Jules Verne. In his novel "The Mysterious Island" the characters talk of taking a walk. And this walk was to be done in a day. They were going to walk 40 miles. My antenna went up with that statement. I used to hike a bit, I walk a lot. And I don't know many people, beyond marathon runners, that can do 40 miles in a day.
