Welcome to Paris of the late 19th century. The aftermath of the Great Revolution offered a new start for each and every citizen, regardless of social class.

Soon, a young woman is brutally murdered - a maid working for an impoverished Lord, a relic of the old French regime. Is Alfred Ethon to be blamed for the murder? The evidence points towards him... But you can change that.
