The Woman in the Window by A. J. Finn
A psychological suspense, a bit like The Girl on the Train. They’re both suspenseful but not scary. Dr Anna Fox suffered from agoraphobia, PTSD ever since the family accident and can’t get out of the house any more. The Russells moved in across the park and then things happened from October to November. It’s really upsetting to be defined as delusional and all the truth thus as hallucinations. Pretty cool to have the chapters set as exactly the same as the percentage of the position of the entire book. But I just kept wondering that just why don’t the characters know some technical common sense. In this way, problems solved pretty easy.
