Macaroni McDuffy helped save Snowy, her friend Anisha's dog. But now Macaroni can't get something out of her head: She's seen a man on the elevator, carrying a jeweled case just like Mrs. Smith's - but Mrs. Smith is nowhere to be found! When Anisha's music box goes missing, Macaroni finds she has two cases to solve. Who is this strange man? What happened to Anisha's music box? And can Macaroni find the culprit without abandoning her volunteer job at the End-of-Summer Bash?
