For a long time, I've heard that there were 36 plots enumerated in an old book called the 36 Dramatic Situations. Well, now you can see them, courtesy of Wikipedia.
Only now that I can see them, I wonder how useful they are Have any of you ever used them? Perhaps there is more in the book.
Here are some examples:
10 Abduction - an Abductor; the Abducted; a Guardian
11 The enigma - an Interrogator; a Seeker; a Problem
