Scarab of Death

A young noble is found dead a block away from Nabulee’s Bazaar of the Extraordinary. Everything suggests that Nabulee was neglectful and left his scarab of death unattended, which ultimately led to the death of the noble. But how did the cursed brooch find its way out of Nabulee’s impenetrable vault in the first place? And why doesn’t Nabulee remember taking it out? Will the characters solve this mystery before the noble’s vengeful father has Nabulee beheaded?
