If you are looking for mystery books for kids, you’ve come to the right place!

Fall is here and for me, that means mysteries.  When I was younger, I remember my mother reading mysteries all the time, and at the time, I didn’t understand why.  That is, I didn’t understand why until I picked up my first mystery and was hooked. 

We made a list of our favorite mysteries for kids – both elementary and middle school-aged. 

We have mystery childrens books from sleuthing and heists to secrets and deception. If your little one loves mysteries, you might want to check out this post on our favorite logic games too!

a study in charlotte

A Study in Charlotte by Brittany Cavallaro

I enjoyed the first book in the Charlotte Holmes Trilogy. I’ve mentioned before that I am a big Sherlock Holmes fan. This Sherlock Holmes retelling differs from the others because it occurs in modern times.

The central characters are the teenage descendants of Mr. Holmes and Dr. Watson. I love detective books that take a different look at a favorite character.

The adolescent angle leaves room for error in Holmes’ deductive reasoning skills. Watson is also a more fleshed-out character who has deductive reasoning skills of his own. This classic retelling wraps up nicely and the characters solve the mystery leaving enough open ends to allow for a sequel.

This is one of my favorite mystery books set in High school.
