Extremely "functional" as a start. Introducing five characters (mom, daughter, professor, detective, doctor) and an immediate first mystery. I'm not necessarily buying the chemistry between them, but you know what this reminds me of? Call of Cthulhu campaign. All the PCs need to get introduced and acclimated to one another before the fun really begins.
It's not necessarily the most engaging way to tell a story, but forgivable! I can see the potential here.
