Unusual take on an intrigue / spy theme. It has prolix descriptions and is high on ambience, but 90% of the game is decoration. Its main problem is hiding difficulty in descriptions. The player alternates between exploring the streets of Paris for hours while looking for places relevant to the game and tightly time-bound, strictly sequenced segments where only the "right" command prevents death. Well written but questionably designed.
