Plot

Tess and Jake try to convince the relatives that the mole truly has framed Erik, but Sal's evidence is needed to prove the mole framed Erik- and to prove Erik's innocence- and to stop the thieves from escaping with the crown.

The kids manage to find the mole, and track him down to the Relatives' hideout in a castle outside Amsterdam. They confront the mole, who they now know is Bernard, but the Relatives, at first, do not believe the children. Eventually, they present enough evidence to show that Bernard is the real mole, having framed Eric for the robbery at the museum. Meanwhile, Detective Simon, Simone, Daniel, and Anika show up to confront Jerry and Lucia. They manage to evade the police, until eventually being found by Daniel and Detective Simon. Bernard escapes with the crown, but it does not last for long as the kids manage to capture him and have the police take him away. Due to capturing the mole, Sal, Jennie, Tess, Anika, are admitted into the Relatives. Without everything finished, the Hunters rejoice, until getting a call from the Relatives that is not a false alarm. The Hunters rush over to see what is happening.—Noah K.
