"The Baron's daughter is missing, and you are the man to find her. No problem. With your inexhaustible arsenal of hard-boiled similes, there is nothing you can't handle."
PataNoir is a homage to the classic stories of hard-boiled private investigators with a knack for describing everything with complex similes and metaphors. In PataNoir, you solve problems by manipulating the hard-boiled metaphors used by the main character to make sense of the world in which he lives.
