Right, that’s another couple of loose ends tied up. You’ve decided that Invisible Inc. lured Aileen to Christchurch because they needed a press witness (56% of the vote – it was close!). You’ve also concluded that Kyle isn’t a police contact for Invisible Inc. (67%).

The next decision is a biggie. Episode 5 is being launched on Friday – and then there’s only one more episode to go. We need to decide how much we want to cover in the final installment. Do we want to stick to solving the crime and confronting the evil Beryl Potts? Or, do we want to explain more of the loose ends and/or find out what happens when Aileen gets back to Edinburgh? We could do either, by using different narrative structures. The options are:

1. Episode 6 uses the same linear narrative as episodes 1-5. We finish the story from where we left off, and show what happens when Beryl Potts is confronted.

2. We fast-forward six months. The episode is based around a voiceover narration where one of the characters reflects on what has happened since the night-time rescue in Christchurch. The visuals would show snippets of the events as they’re mentioned.

Although option 2 is a bit of a cheat (using a voiceover to explain things rather than showing them through action is always cheating!) it’s true to the spirit of Arthur Conan Doyle, who inspired The Lost Book. The Sherlock Holmes stories generally end with Holmes explaining everything to Watson after it’s all over.
