It wasn't that John couldn't tell the story. It wasn't that we didn't know the truth. It was that nobody would believe us. But we cannot keep Sherlock alive with silence.

The reader smiles when Moriarty appears on the page. So does Moriarty. And Sherlock Holmes follows him. We smile because we recognise them.

Scarlett Vendalle is recognised by nobody, except for John Watson. With no recollection of her own identity and a suspected criminal past, Scarlett is the perfect case for Sherlock. As they follow her tracks, red threads appear in their lives that make it more than clear - Scarlett meeting John and Sherlock was no coincidence. Someone has drawn her shadow on the wall before she appeared.  Was it Anne Boleyn who haunts Scarlett with visions of her past? Was it Moriarty who attracts Sherlock like a magnet? Or was it another shadow from the past?

With Moriarty's men on the one hand and the secret service on the other, the stage is set for a game with deadly rules, as Sherlock, John and Scarlett slowly become aware that something larger is guiding their steps...

Is there another story being written?
