Norwegian writer Jørn Lier Horst (b. 1970) and illustrator and animator Hans Jørgen Sandnes (b. 1979) have together created the bestselling children’s book series Detective Agency No. 2 for ages 6-9. Jørn Lier Horst has won multiple awards for his crime fiction for adults, and is also the author behind the highly praised CLUE series for children aged 9-12. Horst’s ability to create charming and believable characters has resulted in a rich universe full of adventure and mystery. Together with Hans Jørgen Sandnes’ award-winning illustrations, the Detective Agency No. 2 series’ universe and its lovable young detective duo are brought to vivid life before the reader.
Set in the idyllic small town of Riverton, the Detective Agency No. 2 series follows the adventures of our main protagonists Tiril and Oliver – not to mention their dog Ocho! Together the two young detectives collect evidence, search for connections, and join the at times perilous hunt for criminals. Concluding each book is an afterword in which readers can put their own sleuthing skills to the test.
