Murder/mystery-suggestions as inspiration

Hey there 🙂

I try to write a fantasy book and a bigger part of the story is going to be a murder/mystery where MC and the investigator are trying to solve it.
But I realised I have never read a book in that direction as I tend to stick more to fantasy, sci-fi and horror and less "real world"-fiction.

So dear redditors, do you have some good recommendations for me that would serve as good inspirations?

Thanks in advance!
