Sherlock

A man in a white shirt and tie holds a rifle, looking toward the camera, while another man's face is blurred in the foreground; the scene cuts to a close-up of a man's profile in darkness, then to a blurry shot of a person's legs on a textured surface, followed by a view of a black door with the number 221B, then a woman with blonde hair standing in a hallway, and finally three men sitting in a room with patterned wallpaper, one of whom is speaking.
