A small case in a cold place
A washed-out PI takes a widow's case about a brass key her dead husband left behind. The key opens a quiet little blackmail operation; what the player does with the contents is the whole story. A tight single-case mystery designed to fit in one sitting.
The first version where one engine could hold many games. The system was no longer locked to one story.
Dark cold-weather noir. Hard-boiled, melancholy, restrained.
