There are two solutions to the mystery of finding yourself in a story from over a hundred years ago. Solution 1: you have been fooled by a clever fake. That would not happen to Sherlock Holmes, who has for once himself consulted experts on the matter without revealing his own identity to them. Solution 2: the stories are genuine and it turns out you are just a fictional character who finds himself in the wrong time period.

The only person at 221B who can’t find themselves in the stories is amnesiac Scarlett Vendalle, whose forgotten criminal past and love for John resurface as she finds out why she is seeing visions of Anne Boleyn...
