Like many a discerning reader and/or detail-oriented writer, I love a good imaginary murder as much as the next lass or lad. Some unsightly vomit; a wee bit of blood ozzing from the nose and mouth; and an embarrassing amount of poo staining the victim's... well... "southern regions," how does a writer know what drug, in dosages, are just right for those desired effects?
There are several books on the subject of how a writer might go about killing, maiming, or otherwise incapacitate a victim or hero, but most of those books are from a forensic view of murder most foul. This book, THE GRIM READER, is from a pharmacological perspective: what drug / toxin in what dosage will do the trick--- and how it reasonably progresses in the real world to write a believable narrative / descriptive.
My cozy series needed some chemical help when it came to threatening the main character and the law-enforcement officer / potential "love interest" (as cozies are wont to be) trying to put her behind bars. I had the desired symptoms, but not the toxin(s) in mind: this book was/is just the ticket to find what I, and my antagonist, were looking for.
Along the "reading way," as it were, I discovered that humans are batshit crazy with what they consume, inject, insert, and inhale just to get the symptoms most of us sane humans wish desperately to get rid of (and pay top dollar to medical professionals to treat). In humanity's defense, of course, we are just modified, tailless apes. But gosh!
