Mary Reklev (84) is Norway’s first female private detective. With over 40 years of experience, she solved more than 1000 cases. The people that came to her for help all had something in common – a fear of being deceived. But what they did not know was that Mary shared the same fear. The man who taught her everything about detective work, with whom she shared both an office and a home, betrayed her. In “the Shadow” Mary attempts to solve her last case: herself.
