LOL! Well I would withhold the Agatha Christie novels. She was a nurse and she researched her poisons thoroughly.
I also think it's funny that a story about wizardry is popular. Perhaps they think that they can find he who must not be named?
Heh.
Ironic since people didn't say Voldemort's name because they were TERRORIZED by it. Harry eventually starts using it because he refuses to be terrorized.
