Homicide officers specialize in investigating serious crimes involving murder, but in Nocturnal Mystery they will have to take on a case in which nothing of the sort has happened yet. The police station received a complaint from a security guard at the city museum. In the hall where stuffed dinosaurs and skeletons are displayed, strange suspicious sounds have been heard for several nights, similar to the growling of animals. But this cannot be, because dinosaurs became extinct long ago. Someone decided to play a trick on the guard or scare him, in this case the attackers succeeded. There is something behind these so-called jokes and detectives: Sarah, Paul and Donna will have to find out in Nocturnal Mystery.
