A paperback puzzle book by Tim Dedopulos that wraps logic, memory and deduction challenges in Sherlock Holmes settings. It leans on the Mind Palace idea: you work through memory and observation puzzles rather than only word games. It suits casual puzzle fans and Holmes devotees who want a themed brain workout, and it sits alongside other Sherlock puzzle titles as a lighter, more memory-focused option.
