Welcome to Victorian London!
The stories of Sherlock and Enola Holmes happen during the Industrial Revolution, a time of big changes.
In the 19th century, England changed from green farms to big, smoky cities with factories and steam trains. London was very busy and modern, but it was also a difficult place for poor people.
Many women and children worked in dangerous conditions for many hours.
In this world of machines and mystery, Enola Holmes doesn't just solve crimes; she also discovers the real life of the workers who are fighting for their rights and a better future.
