To venture boldly is the spirit of Holmes. Enora Holmes (Millie Bobby Brown), who has just tasted the taste of solving a case, is still unsatisfied and decides to follow in the footsteps of her brother, the famous detective Sherlock Holmes (Henry Cavill) and set up her own detective agency. She never expected that the female detective business would be so difficult. She reluctantly accepted the cold reality of the adult world and was about to close down when the penniless match girl came to her. Enora finally received her first business deal and was entrusted with finding the girl's lost sister. However, this case was much more complicated than she imagined, and Enora walked into an unfamiliar place and was in danger. She visited London's eerie factories and magnificent concert halls, blended into the top of society, and even returned to 221B Baker Street. Enora realized that a bloody conspiracy was about to break out and had to urgently call on her friends and brother Sherlock to help her out of trouble. This detective game is exciting again!
