The Body on the Beach - Chris Wieland - Bog

In Crabtree, Michigan, winter can be murder.

Thirteen-year-old girl detective Kat Dylan and her little brother, Alec, are back!
Even after cracking the case of the century, Kat and Alec are still stuck in Crabtree, and suffering through a long, cold winter. When a middle school mean girl approaches her with a problem, Kat can't imagine it's worth her time-or that there's a chance it will lead to the next big mystery. But then Gabby becomes the focus of the local police, especially Kat's Grandpa Nick. Before Kat can get to the bottom of things, she finds Gabby dead.
As Kat and Alec try to solve the murder, they find themselves at odds with kidnappers and killers, private eyes and cops, and more than a few kids and adults who would just like them to go away.
