Professor Heine sends the princes on an assignment to investigate rumors of a criminal in the palace, and the truth shocks them.
That there was a gap 
between the rich and poor.
.وأنّه كانت هنالك فجوة بين الأغنياء والفقراء
Zwischen Reich und Arm
klaffte eine Schere.
La brecha entre ricos y pobres
La brecha entre ricos y pobres
On a parlé des inégalités,
de la survie difficile des orphelins…
I bambini orfani vivevano in strada
Havia uma lacuna 
entre os ricos e pobres.
Между бедными и богатыми была пропасть.
