It's just a dialogue-heavy short story through which you click.
You are a prominent lawyer in 1950's New York. An accident (or was it an assault) all of a sudden turns your life upside down, and you need to find out whom you can trust and whom you can't.
The story got me hooked up from the first moments, and the implementation is generally smooth. The pacing is pleasant, I was gently being directed through the events but never felt rushed.
On the con side, there's a lot of typos in the text, and conversation parsing could have done with an additional synonym or two to make it more intuitive. What some will rate as a design flaw is the fact that you can't play the game in one session - you will make mistakes and need to learn from them. Since the game is not overly complex I personally have no issues with this - if I know it up-front, which is the case here, as the game notes prominently mention it.
Big recommendation. If you're fluent in German, that is.
