The Woman in the Window by A.J Finn

Child psychologist Dr Anna Fox is suffering from agoraphobia following a trauma, and hasn't left her five storey house in ten months. She spends her days drinking, spying on her neighbours and watching her collection of old black and white movies. When she sees a woman stabbed in the house across the street she needs to work out what happened and who she can trust.

The book was unputdownable from the first page, although about 100 pages in, when she still hadn't seen whatever she was going to see across the street, I started to wonder where the book was heading.  At 425 pages it's a long book, but there are enough events and plot twists that it could have been longer and still been great. Anna often has old movies playing in the background. The incorporation of lines and themes from the movies with the scenes in the book is masterful. I can't wait to see the film version (with Amy Adams) due to be released in May 2020.
