The Key: Strongwall Prison Break

There has been a spectacular escape from prison: three known criminals from previous The Key cases have escaped. How could this happen? The most difficult case of the series The Key is going to make you rack your brains, because this time you are going to need something more than intuition. Research all the options and cleverly combine all the clues about escape methods, laundry carts, hideouts and gang membership. Find the correct numerical code and use the key to put the three dangerous kingpins back behind bars. Attention: it is not necessarily the fastest detective who wins, but the most efficient one.
