There are three secret passages: one underneath the library, one underneath the fountain, and one underneath the hay bales (Mordred's secret laboratory). To use the hidden stairway in the castle library, get the gold coin from the fountain, and pay your admission to the Mordred Museum. Get the Library Slip from the stack of books. Go to the castle, first floor right, and enter the Library. Go to the lower aisle (Non-Fiction) and press the shelf marked Mc-M. To get to the room under the fountain, you need to get the note from the maid's room in the castle (first floor left). Take it to the Rumour Mill and talk to the girl in the black dress. She will give you the Mystic Symbols password card. On the fountain plaque, press the three symbols and then the Sun. The tunnel will open and you have found the lair of Mordred's followers!
