In 1970 a the remains of a woman were found in the Isdal valley near Bergen, Norway.  She was burned over the front of her body and unrecognizable and strangely all of the tags on her clothing were removed as well as any other identifying marks on any personal items.  Police have speculated about her identity for over 50 years, slowly piecing together strange facts that lead many to think she was a spy.  The investigation into her identity has recently been reopened using modern technology that has yielded some new clues, but the mystery remains.
