Done Already?

I finished my story and that was one heck of an ending. In what may not seem like, but really is short, The entire case was being looked at in the wrong way until the last five pages of the story. Every single person except two had lied in the story involving what had happened. One witness didn't even see anything, they had been paid by someone who wasn't even under suspicion in order to confuse the protagonist Perry Mason. The original person who was thought to have been killed had already been dead for two years and the same person who paid off the "witness" stole their I.D. due to the fact that they had a similar description in order to have a abck-up name in case of emergency or incase he didn't want to be recognized. It is all still somewhat confusing to me, I'll have to re-read the last 10 pages again later.
