I'm a huge fan of the Psycho films, the last time I watched Hitchcock's version was last week, so I thought that I would not enjoy the book very much, as I already knew the story and the twists very well. However, I was surprised by how much of a page turner it is, it's a short book with many events, which keeps you interested and eager to see what happens next (even if you already know!). The film is very true to the book but the book is darker and more graphic (especially the famous shower scene....), making it a very different experience and I definitely recommend the book to anyone who knows and loves this story as much as I do.
