Mystery on the Seventh Floor

Mystery of 7th floor - Barth Thompson Mystery of 7th floor by Barth Thompson is a disappointing five page mystery. I gave it one star because it has poor grammar and typos. The story had potential but it wasn't delivered. I received a complimentary Kindle copy in an Amazon promotion. That did not change my opinion for this review.
