Black Hearts in Battersea

The atmospheric streets and landmarks really bring the story to life. I'm curious whether the author based them on a real place or crafted it entirely from imagination.

The black hearts and secret plots added a layer of intrigue that felt slightly more intense. Was that intentional to add depth or just a reflection of the era?

Their camaraderie feels central to the plot, but I wonder if their bond is meant to symbolize something about trust or bravery in difficult times.
