Unhinged by Sarah Graves

It began with the mysterious disappearance of Harriet Hollingsworth--Eastport's snoopiest resident. Everyone is convinced the old busybody bolted out of town to escape her creditor--everyone except Jake and her best friend Ellie who know Harriet would never leave home without her most prized possession. But before Jake and Ellie can persuade police chief Bob Arnold to open an investigation, they'll need to come up with proof more sinister than a pair of abandoned binoculars.
