This is an excellent post with recommendations about writing crime. Thank you so much for your article, Connie.
I recently began reading a murder mystery where the author used a mushroom to kill the first victim. That’s where this book fell apart—the idea was good, but the facts and execution weren’t.
Using a mushroom stroganoff to poison him was a poor choice because fungi is an undependable weapon unless you are an expert. Also, individually, one mushroom may be more or less poisonous than another of the same kind, rather like people are. Judging how many one would need to kill a three-hundred-pound man takes more thought than I am capable of plotting out.
Also, it was stroganoff, which is basically beef and mushrooms in a sour cream sauce. This author danced over the fact that serving the food at this dinner party would have been a tactical nightmare. It would have been nearly impossible to ensure the intended victim got the poison mushrooms and no one else did, which is how this murder was written.
Agatha Christie knew that and regularly poisoned entire dinner parties, literarily speaking. Her murderers made everyone at the table sick but only the intended victim actually died.
This particular mystery was set in Scotland, and I don’t know how poisonous their mushrooms are, but I think that logic would hold true there as well as it does here in the Pacific Northwest.
If I hadn’t been on several nature walks with Ellen King Rice, a wildlife biologist and amateur mycologist who writes well-plotted mushroom thrillers, I would have accepted the slightly contrived fatal dinner as written and focused on the other failings of this novel.
This experience reinforced my belief that readers are often more knowledgeable than we authors are. E-readers can do the research just by highlighting the word and hitting search.
