A Stranger in the House is another fantastic domestic thriller from Shari Lapena. It seems to be a fairly straight forward and predictable mystery at first: wives with secrets, husbands with secrets, creepy neighbor with secrets and a convenient case of amnesia. Or, is it? At first, after her accident in a seedy part of town she would never have visited and then the discovery of a murder victim nearby, it seems that Karen is probably faking her amnesia. Then other things make us think perhaps she is really suffering from amnesia, because no one can be that good of an actress. Karen lies to the police, her husband Tom lies to the police and their neighbor Brigid lies to the police. But, they all lie for different reasons and about different things. As time goes by it becomes fairly obvious to the reader what happened and then…the totally unexpected.
