Query: Naive, Christian, Not-so-Mysterious Mystery

If you are into very naive detective work where you solve the mystery way before the detective, then this could be for you. Add rose-colored glasses, STRONG Christian preaching, and a detective with no grit at all...then you will love this book. I read it just because it was my first Kindle book and more interested in the action of my Kindle. The price was right at $0.
