The child is father of the man, at least that’s what Wordsworth wrote. (Wasn’t he a loquacious so-&-so?) That means the things we love as kids often influence our tastes as adults. I am (unfortunately) old enough to acknowledge the truth in this observation, but I wonder if writers deliberately trade on this idea. After all, how do you create adult readers who’ll love Fantasy/Science Fiction? Wait until they’re old enough to vote and then give them a copy of Dune? No, you introduce them to the genre while they’re young, with kid’s stories written by great SF authors like Heinlein and LeGuin.
But creating under-age Mystery readers is a slightly more difficult proposition. After all, Mysteries almost always involve Violent Crime, and we don’t want the Little Darlings to have nightmares. (Well, we may, but we won’t sell as many books if they do.) So how do you create the next generation of Nero Wolfe and Alex Cross fans? By giving them mysteries with juvenile detectives, of course!
Early Juvenile Detectives
When I was first learning to read, there were three fictional superstars of kid-lit whodunits. Well, seven characters but three detective teams: Nancy Drew, the Bobbsey Twins and the Hardy Boys. On the page, they were the Wunderkinds.
Contemporary Juvenile Detectives
A whole raft of fictional juvenile detectives have followed these prototypes from Encyclopedia Brown through Flavia deLuce and the newer heroes have more of a real-life kid’s feelings and issues. But the essence of the juvenile detective hasn’t changed: youth’s zeal and integrity, mixed with a world-class intelligence and the emotional maturity of an adult whenever the chips are down. Come to think of it, that’s winning combination at any age.
