Anita and the Mistaken Identity

During Blomkvist's investigation he soon thinks that he may have a suspect. Just when a lead pops up, he finds out that a picture he had been starring at for days of Harriet was in fact Anita, Harriet's cousin. The two girls were very close and spent a lot of time together. Anita does in fact happen to be the girl in the photograph standing by the window. This throws off Mikael and Salander's investigation since they were going off the necklace in the picture that she was wearing. Cecilia was a suspect for an instant after Blomkvist realized she was wearing the necklace that Harriet (or who he thought was Harriet) had on in the picture. After accusing Cecilia of wearing Harriet's necklace, Mikael finds out that it was Anita's necklace and in fact Anita in the picture standing in the window. After ruling out many false leads such as this one, the two were able to make progress in the case and bringing all the leads to Henrick making him so happy that they were closer to finding out were his dear niece has gone.
