Behind Her Eyes by Sarah Pinborough

Here is a story of a lovely married couple, David and Adele. David is a successful psychiatrist and Adele is his loving, beautiful and perfect wife. We learn there was some "terrible necessary act" that happened back "Then" - "a thing had been done that could not be undone." Cryptic and creepy, that. But here in the present, we are introduced to Louise, who is a single Mom with no self-esteem and possibly a slight drinking problem. She is David's new secretary, and this is where this dark and disturbing tale starts to unfold. Our naive Louise has no idea what she is getting herself into when she befriends these two. The one thing she learns very quickly, and we the reader discover before she does, is that this marriage is very, very, messed up and she should cut and run far, far away. This is a well-written psychological thriller that was a quick read, but mostly because I couldn't put it down. Completely unpredictable, shocking in places and kind of insane. I thoroughly enjoyed it!
