I cannot open the secret door in the room with Islanne in it. I think i have all the ward stones, and my thief has a 235% pick locks. (potions). Please HELP!!!!!!!!
I need to get though this door to complete the level, I am stuck.

Me neither. I'm talking about the door south-east of Islanne. :)

Which level are you on? If it's the one with the dummies then hit (attack) them where they show up as red (move your pointer over them) and the door will open. If it's the next level down then you have to visit the stone golem room, which is SW of where you come into the level and speak to Durlag's shade, then answer its' question. Visit it 3 times, different questions.

I managed. Thanks to everyone for their help and patience. My mistake was that when I killed Grael, I never bothered to search his remains on the acidic ground and therefore never found the compass wardstone.

PS: I have a new favourite weapon (except for my bow): The Axe of Mauletar (+2). Lovely, just lovely.........
