What Next?

WIP update:

Life is hazardous for my amateur sleuth, in the case of the defenestrated rock star (hmm, another potential title?). First there is the question of, did he fall, or was he pushed?

Well, obviously he was pushed – it's a murder mystery. But who pushed him? My intrepid sleuth is trying to find out. The one witness to the incident, a doped-up groupie, is found dead before my sleuth gets to question her. An overdose, apparently. My sleuth thinks not. Two victims now, both with the same killer. My sleuth is on the case.

And what happens next? There, in a nutshell, is the problem. I need some small but majorly significant clue, something the police overlook but my sleuth realises is vital to solving the mystery. But I don't, at this stage, know what that clue is or how my sleuth is going to come across it.

So what does happen next? What key thing does my intrepid sleuth discover that's going to set her on the path to solving the mystery.

Honestly, I have no idea. Answers on a postcard please…
