The Key: Escape from Strongwall Prison

There's been a spectacular prison break, and three well-known criminals from previous The Key cases are on the run again! How could that happen?

The Key: Escape from Strongwall Prison is the trickiest case of The Key series because more than just instinct is required here. You have to combine all types of hints and clues to determine escape types, laundry carts, hiding places, and gang affiliations. The right numerical code or key puts the three dangerous gang bosses back behind bars. Attention: It is not necessarily the fastest who wins here, but the most efficient investigator genius!
