Just finishing the semester and looking for a good mystery

I am finishing up my spring semester and I'm going to read a book to wind down while I try to get some vitamin D. I'm looking for a really good fiction book. I normally read non-fiction because I haven't found any fiction book that really captivates my attention and gets my brain running.

i do like movies and tv shows that are humorous murder mystery or just humor mystery. I also like mind bending shows. I was hoping to find a book like this.

what are some books within this type of genre that is not horror or scary at all?
