Fantastic!
A fantastic, in-depth plot blended with the classic 'see/touch' adventure game. I especially liked the police computer, in which you could enter any name you came across and be told their details; it added real depth to the game.
Couple of points: Music, as said before, grains after a while. Either change it or add more atmospheric sounds/sound effects. Also, I often used a hint when I was stuck, yet I feel they are too revealing; they aren't so much hints as telling you what to do.
Otherwise, great game.
