One of the spoilers say that you must use magic to open the secret door . There is another way . It works and completes the score but sometimes it is fatal . Go to the archery place ( where there is a bull like drawing on the board and where you can practice throwing) at daytime (forgot what time) and you will see the dude at the town gate ( the thief) talking with a brigand.They will talk about the password. Save the game . Walk to the middle archery place ( you have to walk around). Sometimes the bad thief will catch you so its purely luck . Then when you reach the brigand at the archery place , kill him and search his body to get the key to the secret door . Open the secret door . Talk to yourself or the door to say the password . If you say the password , the troll will disappear . Then follow the passage and you will land to the front door of the brigands fort . Another way is picking the lock using the toolkit , if you are a thief . This will increae your lock picking skills.
