As a kid, I read every Hardy Boys and Nancy Drew book I could find.
My oldest daughter (34) read all the Encyclopedia Brown books and solved the mysteries before he could! They are about a young detective who solves mysteries by astute observation and keen listening abilities.
My youngest daughter (18) has the ENTIRE collection of Nancy Drew. When she was in 2nd grade, she prevailed upon her daddy to order them for her. Because she was his princess, he complied.
If I remember correctly, it set him back around $400! His investment has paid off tremendously; she's an Honors Freshman at university with a 4.0 GPA.
All of my g'children (6) are extremely well-read. It's a blessing to see that, and I'm very proud of them. Can you tell?
