Query: A page turner.

I honestly didn't know until the very end whether to believe in the inmate's innocence or not, and to me, that is what makes a good mystery. I have never read Ms. Rooth before and was pleasantly surprised. Her writing flows easily and is smooth and undented, her facts are presented interestingly, and her characters are extroverted, likeable and warm. I hope Ms. Rooth will continue writing novels like this.
