The scene changes to a high angle shot of Somerset walking into the entrance to the library. This angle makes you feel like you are looking down on him or maybe it is the street baring down on him as the angle suggest who is looking has the power over Somerset. He walks into the library and it is a very calming influenced compared to the ugly sites of the street outside, it looks bright in places, which links back to Fincher using a film-processing technique that deepens tonal qualities and makes whites harsher and brighter. It gives the impression that it is like a haven from the street, a place where you can go to get away from the perils of the city outside.
As Somerset walks towards a table his footsteps resonates around the library, which creates, and eerie atmosphere, and for a moment you don't feel so safe you did a minute ago. Somerset looks a changed man, he looks calm and in control as if the library is a place that he understands and he knows what to expect. It seems to be giving him relief from outside and the library appears to be an uplifting factor for him. Unlike outside in the city and in his job where he doesn't know what is waiting round the next corner and as he is close to retiring and has had enough of this unstable element in his life and that what was making him look so despondent.
At this point one of the security guards turns on the radio and out comes Bach's "Air on a g-string" this provides a tremendous sense of sadness and serenity which seems to embody the character of Somerset. This music also provides an uplifting backdrop to the tense atmosphere, which has been created in the scene.
As he walks passed the bookcases looking for books on the seven deadly sins, the camera follows him from behind the book cases, the camera angle is facing up towards Somerset which gives the impression that he has the power and control because we are looking up at him.
