To give you some idea of how long ago it was between buying this book and when I actually read it, the book makes a reference to the movie Jurassic Park being currently popular in theaters. When I read it, Jurassic World was owning theaters everywhere. Despite being published in the mid 1990s much of the information in Modus Operandi, a writer's guide to how criminals work by Mauro V. Corvasce and Joseph R. Paglino is still relevant - especially if you're writing anything set pre 1996 and want to be aware of how things were 20+ years ago.
