"Lasse and Maja's Detective Agency" is a series of novels set in and around the small town of Valleby in Sweden, where the two main characters, Lasse and Maja, run a small detective agency and solve a series of exciting and puzzling mysteries.
Martin Widmark, the author of the book, told those gathered at the ceremony that his teaching career helped him learn about children's reading preferences.
"As a teacher, you would always think about how you should explain this or that to a child. And that's also with me when I do the books because I always think about the reader when I write."
