When writing a story that involves poisoning in the plot, what every writer must remember is plausibility is important. How do you achieve that if you are not a pharmacist or some other medico, you must research. Short of interviewing a chemist, botanist, or even an emergency room doctor, you look it up either in a book or online. Doing it online always gives me the shivers as friends warned to clear my browser history. The same with checking out books from the library. All that has all be solved by the authors of this book.
It was written by authors, for authors and presented the way authors think. Yes, there is a listing of poisons, how to administer, what to expect as far as affects, and if there is a remedy/cure. So many to chose from! But these two women packaged is sub-listings from deathly to bothersome; from length of torture to death; they even ranked in a class (using a standardized medical system) how deadly a poison can be.
If you are a writer of mysteries, crime, fantasy, westerns, or frankly any genre that requires exposure or administration of a poison, this definitely a book to keep in your reference library to use and recommend often.
