Red Leech (Young Sherlock Holmes )

The setting feels so authentic and immersive, but I wonder whether it was based on extensive research or a creative choice to serve the plot.

The characters aren’t clearly good or bad, which made me question my own judgments. Was this intentional to reflect the complexities of that era?

The time period adds so much depth to the crime elements, but I’m curious if the author had a specific event or issue in mind when choosing this era.
