Courses
Five files, each one solving a single problem thoughouly. Every file stands on its own, carries its own glossary, and ends with the work done rather than a reading list.
In order they run from the terrain you are standing on, through the four ways in and how a con actually works, to what is already published about you and the routine that keeps all of it shut. Start with whichever one worries you most, or take the whole set.
Downloadable PDFs. Nothing to install, nothing to sign up for.
