The scene is edited to concentrate the audience's attention on the detective. POV and over-the-shoulder shots are employed to manipulate the audience's level of identification with the character. All evidence points to him living alone and living a simple life centered on his work as a detective. A lot of effort has gone into introducing this character to the audience in depth; in just a few seconds, we have a general idea of the detective's personality.
The body receives little attention and is only shown for a few seconds from a high angle, implying the victim's lack of power. There is no background music in this scene; the only sound is the diegetic background effects of Somerset's urban environment. There are people shouting, dogs barking, and traffic noises. These are noises that are typically heard in the morning, so there is also a rough indication of the time of day.
By watching this film, I learned a lot about the genre and was inspired to create a new version of my sequence.
