Harry was sorting through the photos he had inherited when he found it.

Sirius was gone, and Remus had retreated into the mountains, to a place of gathering for werewolves. He had left Harry all Sirius' belongings, and everything else he would not need.

Harry didn't think he could have found this picture, or he would have taken it with him. The things it showed shouldn't be seen by just anybody. Oh, it was perfectly innocent to a casual viewer: there was James and Lily, and Sirius, Remus and Peter.

But the look in Sirius' eyes as he gazed at James made it intensely private.
