A Long Running Book Series, beginning in 1927, for kids and teens created by the legendary Stratemeyer Syndicate under the pseudonym Franklin W. Dixon. They follow the adventures of Frank and Joe Hardy, a pair of brother detectives. Frank is the logical, calm one, and Joe is the more impulsive, instinctual one. The series (alongside their Distaff Counterpart and frequent Crossover partner Nancy Drew) invented or popularized most of the Kid Detective tropes. Definitely not to be confused with the wrestlers of the same name. They seem a bit prone to a Crossover with Nancy Drew.
