In this excellent middle-grade mystery, the town of Windy Bottom is thrown into a tizzy when a skeleton is discovered under the town’s playground. Rumours abound, but when Coop’s grandpa becomes a prime suspect, he and his friends decide to help the police investigation along. The more research the kids do, the more they discover long-held secrets that point in unexpected directions. This was a story that was hard to put down, and I will definitely be recommending it more frequently in the library now that I’ve read it.
