It's an interesting premise to a story, and though it seems like it shouldn't work I feel like it really will. I love historical fictions, especially ones which have a modern twist to the writing but still keep it traditional in style too. I'm looking forward to seeing where these Jack the Ripper vibes come from and how dark this story goes! The fact that you've said it's going to be juicy makes me feel it will be drama and darkness a plenty so I'm instantly subscribing.
Also, I kind of get a Romeo and Juliet vibe too, which I love. I'm really looking forward to seeing where this goes and how you develop the characters.
