Game recommendation please!

Hi, I have just finished playing CSI dark motives and it was fab. Could anyone recommend similar games in the fact you have to solve puzzles collect stuff things like that.
I have got Professor Laytons Curious Village but would like some thing a bit more "grown up".
Thank you muchly ;D

On the DS, you could try Hotel Dusk it's a noir mystery novel game. On the pc if you can find it somewhere try Phantasmagoria, it's a FMV adventure game with some cheesy moments, but also some scary.
