“The Girl Before” by JP Delaney

I want to thank NetGalley and Random House Publishing Group, Ballantine for the ARC of “The Girl Before” by JP Delaney. I was intrigued by the plot and various twists of this terrifying psychological thriller. JP Delaney uses the concepts of perfection, flaws, instability, strengths and weaknesses as part of her characters descriptions. She compares them to computer ratings,ideals, architecture and buildings. There are several murders that occur in the past and present in a specifically designed architects apartment. How are the murders connected? Who are the suspects?This novel had me second guessing and I would recommend this book.
