[SPOILERS] A bit stuck I guess...

[[fll.fi] Henry Gordan]

I've played for three hours. And now I'm really stucked. I have two keys, Wanda's and the one found from mansion. I can't find any code keys anymore for any of the numberlocks. I also can't find any proof about the killer.
I've found out about Sofia's death and the bookcase door. But not the way to the bathroom next to the stairs to excercise room. Or the possible secret room at next to the very room

Also, I can't find anything useful from the hospital.

Edit
I have visited Dorothys house and garage and now I have a guess about the suspect, but I have nothing on him but a hunch

I'm not entirely sure where you are in the game, but have you triedchecking the wardrobe in Trisha's room or one of the drawers in the Tea Room. Things will start opening up from there.
Hope that helps

[Charge]

Also if you are stuck at the hospital, have you found the id card? I missed it for a pretty long time because of it being white/blue on a bright blue background it's in the large warde in the gound floor (first floor for americans)

So I got to the end with only few hints. Thanks to dev's for the hint of second drawer of Trisha's nightstand I managed to get 94% and Grade A \o/. The end was in sigh when I dicovered that Derrick didn't do it. Great game!
