Mystery novels help young readers develop their powers of observation and problem-solving skills. Kids will love classic mystery series such as The Boxcar Children, Nancy Drew, The Hardy Boys, or Encyclopedia Brown, but considering how tech-savvy most toddlers are and how much our language changes over time, you may have to explain a few things. I remember my sons asking me what  “jalopy” meant and why the detectives didn’t have cell phones or computers. Many of these books have been updated or reissued and new books in modern settings have been added. In honor of our May mystery issue, I’m mixing some contemporary mysteries with the classics to help spark their natural curiosity.
