For the task to think of some initial ideas that we could present to the group, this is the best idea that I've thought of so far:
The sequence begins with an intense flash of light. Then, we realise that this is the inside of an apartment and the flash came from a crime scene photographer's camera, which we saw from a corpse's point of view. Also in the apartment are two detectives talking about the crime when one of them goes over to a window to look outside and think. From outside, we see a person looking up at the window just as they are taking of a blood-stained glove.
