Sherlock Holmes may be the world's greatest detective, but he needs your help.

Join the renowned sleuth and his assistant Dr Watson as they travel across Victorian England, encountering mysterious crimes along the way. Using just Watson's illustrated case notes, can you unravel the twists and turns of each remarkable story?

After reading ten original cases, you will need to solve baffling questions such as:

* Who murdered the High Court judge, and why?
* How did the Baker Street Irregulars know the warehouse robbery was an inside job?
* And did the stonemason really die in a climbing accident?

Are you up to Sherlock's challenge?
