The Junior detective series TKKG is a series of radio plays and novels created by Stefan Wolf. In all German-speaking countries they are one of the most commercially successful series of novels of their type. They call themselves TKKG, after the initials of their names: Tarzan (later renamed in Tim, because "Tarzan" is a trademark), Karl, Doughnut (in German Klößchen, in Australia called "Klumpling") and Gaby; an unofficial fifth member is Gaby's Cocker Spaniel, called Oskar.
