Murder in Gatlinburg — Steve Demaree

When two homicide detectives retire, they are given a week at a resort in Gatlinburg, Tennessee as a retirement gift. The two, who have never been on vacation are to become a part of a bus tour group. But when they arrive at their destination, one person from their group disappears, and shortly thereafter another goes missing. One of the detectives is itchy to check into the situation, while the other reminds him that they are retired. Nothing changes when they learn that one of the missing people has been murdered. This seventh book in the series is filled with sightseeing, laughs, and a good whodunit that needs to be solved.
