How do you know if your book is a mystery or a thriller? Couldn't it be identified as both? What would you call that then? Or is it better to just say one or the other?
Also, I read that thriller is about suspense, but doesn't mystery have that too? Does anyone have a clear definition of the two that I could read? I would appreciate it.
