I'm looking for a book I read in the last couple of years. My guess is that it came out 2005 or later.

It's about an unsolved mystery being tackled in a college class. The instructor is new, only about 12 people in the class. Parts of the unsolved mystery start to appear or get "replayed".  Turns out the class was somebody's PhD thesis and 2 people in the class were the "experiment" all the rest were actors.  One figured it out the other died cuz it went too far.

Does this sound familiar to anyone? Any idea on the title or author? I've tried all kinds of searches and can not find it.

The book that you are talking about is "Obedience" by Will Lavender.

Here is my honest review of the book:
