This is the opening credits to the film 'watching' i chose this because it is a great thriller and really ticks all the boxes of what it has to have. The music is very high pitched and has a slow tempo. The books and the blood suggest a kind of detective murder case.Also some of the credits are done on a knife an also written in blood.The sense of books could relate to a library which is quite so we now it wont be brutal murders but more mysterious smart murders.
