Mini Crimes: The Drowned King

From BoardGameGeek:

In your hands you have an investigative case that you can play alone or with friends. It takes little space, a bit of time and a lot of ingenuity. But remember, one case leads to another! Six chapters for six compact boxes to carry with you in every situation: the box itself contains the rules of the game, and along with the deck of cards contained in it, it will be enough to get all the clues necessary to the resolution!
