Detektivbyrån ("The Detective Agency") was a Swedish electronica and folk music trio from Karlstad. The group consisted of Anders "Flanders" Molin (accordion, music box), Martin "MacGyver" Molin (glockenspiel, traktofon, toy piano, Theremin) and Jon Nils Emanuel Ekström drums, sound box, small bells.

The three members grew up in the city of Karlstad, Sweden, located in Värmland County, but they did not form a band until they had moved to Gothenburg in 2005. The usage of more unusual instruments such as the accordion was inspired both by its prominent use in the soundtrack for Amélie as well as musical traditions in Värmland. As the band also played as street musicians there was originally also a requirement to have portable instruments such as the glockenspiel.
