Shot 3 [6–9 s]: Close-up of the detective’s focused, determined eyes as distant sirens wail and he frowns slightly in thought. Shot 4 [9–12 s]: Medium shot of the detective moving carefully down a dim hallway, his flashlight illuminating the path ahead. Shot 5 [12–15 s]: Close-up of the detective discovering a key clue, his face lighting up with sudden realization."
