Pět malých školaček z Vermontu požádá Magnuma, aby našel jejich zmizelého učitele.

Tijdens zijn zoektocht naar een vermiste leraar, ontdekt Magnus een ander mysterie.

It's the Christmas season, and against his better judgement, Magnum agrees to being hired by five young schoolgirls to find their teacher, who has seemingly gone missing after falling in love. While he's working on the case, Magnum manages to convince Higgins to let the young girls stay on the Masters Estate, but he's unaware that he's being deceived in a scam over a valuable painting recently purchased by Robin Masters...

Magnum est chargé, contre son gré, de retrouver le professeur disparu de cinq jeunes filles, une certaine Mme Bootom. Les étudiantes demandent à Higgins de les héberger...

Magnum lässt sich trotz unguten Gefühls zu einem neuen Fall überreden: Fünf Schülerinnen überreden ihn, nach ihrer vermissten Lehrerin Linda Booton zu suchen. Magnum stellt fest, dass Linda gar nicht verschwunden ist, sondern nebenbei als Kunstfälscherin arbeitet.

E' il periodo di Natale e, contro ogni buon senso, Magnum accetta l'incarico da cinque studentesse per ritrovare il loro insegnante scomparso. Mentre sta lavorando al caso, Thomas convince Higgins ad ospitare le giovani clienti nella tenuta di Robin Masters. In realtà Magnum è caduto vittima di un elaborato raggiro che ha come obiettivo un quadro di inestimabile valore recentemente acquistato dal padrone della tenuta.
