Disclaimer: Though Dick Wolf and JK Rowling have never met (I don't think), their respective creations do so here. And not entirely incompatibly, I might add.
This follows "Simple, Neat and Wrong," which is a sequel to "Pure Statesmanship," which is a sequel to "Animalie Carnivalie," which is a sequel to "Adjustments and Adaptations," which is a sequel to "An Altered World View." I highly recommend that you read them in order.
Special thanks to "The Harry Potter Lexicon." Again.
