Deadly Doses: A Writer's Guide to Poisons

Depite having taken numerous classes in toxicology, this book helped me more when trying to write about poisons when writing short stories. It describes how the poisons work, how fast-acting they are, what forms they take-generally, everything a frustrated mystery wanna-be writer could need. -I didn't do any fact-checking in this book, though, so you might want to cross-check the information given in a toxicology book just to CYA.
