Fun fact: Tom Sawyer did grow up to become a detective. In his later years, Mark Twain wrote a novel entitled (wait for it) Tom Sawyer, Detective in which the lovable scamp, now 17, solves a murder. This accounts for the portrayal of Tom Sawyer as a crimefighter in Alan Moore's brilliant graphic novel series The League of Extraordinary Gentlemen.
But wouldn't Huck Finn make for an even better detective? Can't you imagine that riverboat scoundrel, as perceptive a character as any in American fiction, walking the streets of turn-of-the-century New Orleans, solving the crimes deemed too uncomfortable for the corrupt authorities to touch. He would never have a steady girlfriend or even a steady office but stability has never had much appeal to Huck. He might even have to cross paths with his old friend from his younger days, Tom Sawyer, who has now become an upstanding member of the United States Secret Service. Tom tries to keep the heat off his dirty-dealing well-intentioned pal but it can't be long before the two men square off.
This is the New Orleans of Storyville, of the Chief Hennesey Riot, the Robert Charles Riots. This is the New Orleans of the Black Hand Gang. The birth of jazz is on the horizon.
I don't know about you, but I'd love to read these stories.
