Found via the fine Coilhouse blog (which in turn was discovered a few days ago after a middle-button-click crisis), these Swedes are a strange mix of music box, electronic and folk music. This video made me crave for more, but fear not, the two albums they've already released can be found in the usual places.

Update: Forgot to include the link to the (quite ugly :)) Detektivbyrån's webpage, thanks Erik for noticing.
