The Ultimate List of Mystery Books for Children

We love a good mystery book around here. Mysteries are a great choice, especially for young children, because kids can use their deductive reasoning skills, search for clues and pretend to be sleuths, all while strengthening reading skills. Here is our ultimate list of mystery books for kids, from picture books to chapter books, there is something for every young reader.

Baby Monkey, Private Eye by Brian Selznick and David Serlin.
This is one of our favorite books and my littlest one can read it over (and over) again. While this may seem like a chapter book, it is decidedly a picture book as well!
