Even villains no longer smoked or drank, and scenes involving guns and shoot-outs were compressed or eliminated, in favor of criminals simply giving themselves up. The boys, too, become more respectful of rules and of the law; for example, they no longer drive faster than the speed limit even in pursuit of a villain. The Hardys also became more and more wealthy, prompting the criticism that the "major problem in [these volumes] is that the Hardy Boys have risen above any ability to identify with people like the typical boys who read their books. They are members and agents of the adult ruling class, acting on behalf of that ruling class." The "Hardy Boys" began to be published in paperback in 1979. The Hardys were also featured in two new series, the "Hardy Boys Casefiles" and the "Clues Brothers". The latter series, modeled on the "Nancy Drew Notebooks", was aimed at a younger audience, and ran from 1997 to 2000. In contrast, the "Casefiles", begun a decade earlier in 1987, was aimed at an older audience than the "Hardy Boys Mystery Stories". In the new series, the Hardys' work with a secret government organization simply called the "Network", with which they collaborate to "infiltrate organized crime, battle terrorists and track down assassins around the world." The Hardys' personalities are portrayed as more separate and distinct, and they sometimes fight; in the first of the series, "Dead on Target", for example, the brothers brawl after Frank tries to restrain Joe after Joe's girlfriend, Iola Morton, is killed by a car bomb. In general, the series is more violent, and the Hardy Boys carry various guns; Lines like "Joe! Hand me the Uzi!" are not out of character. Barbara Steiner, a Casefiles ghostwriter, describes a sample plot outline: "I was told that Joe Hardy would get involved with a waitress, a black widow kind of character, and that Joe would get arrested for murder. I was told the emphasis was on high action and suspense and there had to be a cliff-hanger ending to every chapter." The long-running "Hardy Boys Mystery Stories" series ended in 2005 and was replaced with a reboot series, "The Hardy Boys: Undercover Brothers". In these volumes, the Hardys' adventures are narrated in the first person, each brother alternating chapters. This fresh approach to telling the adventures reveals two boys quite foreign to how they have been portrayed before, egotistical and jealous, and longtime readers will find few connections with the boys' previous personalities.
