I was able to pick up and finish this book on the same day.
It starts off a bit slow, but picks up pace extremely fast, and regardless of how many crime shows you've seen, or your inner Sherlock, the final twist was unimaginable and absolutely amazing.
It's about an open and shut case of a wife who killer her husband that becomes more and more complicated as you read it.
It helps to know that the author is actually a screenwriter and gives you a better perspective on how the book is arranged like a montage rather than a linear timeline. A lot of angles have been explored here, psychotherapy, art, literature and in my opinion has been brought together very smoothly and in unexpected ways.
I recommend this book highly.
