This reminds me of the following: Of fictional crime investigators, mrs Marple collects all the clues and then invites everyone to the Great Summation at the end to reveal the murderer. Episodes of Inspector Columbo start with the very act of murder, and the perpetrator is clearly visible. We then follow Columbo collecting clues and discovering the motive. We tend to be like Mrs Marple when we should be more like Columbo.
