I just discovered Nature's Poisons, a forensic toxicologist. It's got all kinds of natural poisons (animal and vegetable) and appeals to my geeky, science and gardening loving heart. It's got a bit of history and would appeal to the CSI and Sherlock crowd.
Of course, now I have to use it in a book. Also, I have to figure out where all the "cool kids" food scientists hang out, because I love reading about foams, emulsions and crystallization.
We all need a hobby.
