Siblings Alex and Zoe Sherlock take their last name as inspiration when choosing a summer job. After all, starting a detective agency has to be better than babysitting (boring), lawn mowing (sweaty), or cleaning out the attic (boring and sweaty). Their friends Lina, an avid bookworm, and Yadi, an aspiring cinematographer, join the enterprise, and Alex and Zoe’s retired reporter grandfather offers up his sweet aquamarine Cadillac convertible and storage unit full of cold cases. The group’s first target is the long-lost treasure supposedly hidden near their hometown Miami.

It’s the first week of senior year at Meadowbrook Academy.

Dexter Foreman is twelve going on eighty. He has lived at The Pines retirement village with his grandmother since he was six years old, and as a result he gets along better with senior citizens than kids his own age. He's homeschooled by the residents up until the day the county’s truancy officer shows up and announces that Dex has to go to a “real” school, to the local middle school. At school, Dex sticks out like a sore thumb. He dresses like a grandpa (and can be just as cranky). His taste in movies and music is decades out of date.
