Arthur, Roza, Viola, and Luke are known as “The Triasin Quartet.” Though they’re only fourteen, they’re already an experienced team of young detectives.

One day, the kids overhear someone blackmailing Emil’s father, the curator of their local museum. In exchange for keeping a certain secret, the blackmailer demands that the curator hand over a crate of artifacts prepared for an upcoming exhibition. The exhibit has been heavily promoted and is set to open soon, yet its contents remain a mystery. If the show doesn’t go ahead as planned, the curator could lose his job and even face legal action over the missing items.
