The year is 1989, and the Berlin Wall is coming down. The East German secret police, the Stasi, are shredding documents in a desperate effort to hide the secrets they have been collecting on their own people for forty years. They have no idea that only a few years later a group of people will come together to piece all of the shredded documents back together. Annie O'Shea is one of those people. She is a puzzle person. But as the pieces come together, Annie uncovers the incredible story of two couples split apart when the Wall went up in August of 1961. She also discovers a tangle of betrayal, espionage, mystery, and murder. Even worse, she has no idea who she can trust.
