Bill Bergson (Swedish: Kalle Blomkvist) is a fictional character created by Swedish writer Astrid Lindgren. The first book featuring him was published in 1946.^[1]

Lindgren's detective story is about Bill Bergson, a more-or-less ordinary Swedish boy with an extraordinary fascination with detective work. He lives in the small town Lillköping. He identifies clues, investigates enigmas, and solves the riddle surrounding a mysterious stranger while the police and other adults overlook or dismiss the whole matter. He and his friends several times solve real crimes including mysterious thefts, murder and kidnapping. Lindgren wrote shorthand for Harry Söderman, a doctor in criminology, and it was during this work that she learned the basics of criminology that she later used in her stories.

Bill and his friends also play a game they call the Wars of the Roses. He, along with his two friends Anders and Eva-Lotta, are the White Rose, while three other kids, Sixten, Jonte and Benka, are the Red Rose. They "fight" over the possession of Stormumriken, an oddly-shaped stone. The group that does not have the stone must use all their wits and energy to obtain it. The group that has the stone must give the other group clues on where to find it.

Although there is a "war" between the two roses, all six of the youngsters are good friends and there is simply a playful rivalry between them. The Red Roses help the Whites when they are threatened by real dangers.

Lindgren wrote three books about Bill Bergson:
