Katelyn, Sherlock Holmes’s adoptive daughter, arrives at 221B Baker Street, raising questions about what she may have discovered about her father. A charming clairvoyant has also moved into 221C, and Holmes is caught between fatherly love, occult rituals, and a desire for vengeance.

For the first time in his career, the detective must protect a secret rather than expose one. Players take control of Holmes in an adventure that includes intense action sequences and investigations across London.

Search the city’s districts for clues, follow multiple intertwined intrigues, interrogate suspects, collect evidence, and gather testimony. Your deductions shape the outcome, and the consequences of your choices must be faced.
