Here is my issue. Whenever I watch a modern crime drama the same thing always happens: - The murderer is always the person you would least suspect, which means that without fail it is the nice copper or the husband of the main female character. Always, without fail. I can walk in the room while one of these by-the-numbers TV crime dramas is on, look at the screen for a few moments and point out that the murderer is that nice male copper, and lo and behold, 5 episodes later, it is. Now, if this weren't such a tired formula there is obviously a huge emotional pay-off to get from making the murderer a likeable, trusted character. But how do you do this without erecting a neon "murderer" sign over their head?
