When a shady stranger appears in Malvern, Finley suspects that he's up to no good. After Dale refuses to investigate with her, Finley takes matters into her own hands-after all, it's worked before!
But with Rusty trying to involve her in an illegal scheme, Dale wanting nothing to do with her adventure, and Finley's mom distracted by a new relationship, Finley wonders if she can solve this mystery alone.
Will she discover who the stranger is before it's too late? Or will he take what he came for without being caught?
