Once you deposit the coin safely, can you unravel the mysteries of the vault to get it back?

Among the cluttered proliferation of artifacts at 221B Baker Street lies a silent treasure. A coin given to Sherlock Holmes by the British Treasury. He must protect it from the criminal underworld, where it can finance all kinds of evil plans. While thinking about a cold case, he feels inspired. He takes an old safe and modifies it with a series of panels, notches and tiles that, only when manipulated in a certain order, can open the safe.
