Once he leaves the room, Grace reemerges from her hiding place. Locate the spiral staircase leading down into the library. Place the mouse cursor over the staircase and head down. Head over to the desk and locate the drawer. It's pretty difficult to find, but it's in the center of the desk; it's a very thin drawer. Open the drawer and spot the Immortals book. Don't pick it up. Instead, use your fingerprint kit on the Immortals book and secure Montreaux's fingerprint. After you've gotten the fingerprint, read or pick up the book. Make sure you read each page and use the examine and think icons on each.

Look at the Montreaux portrait on the wall behind the desk. Move the mouse cursor on Montreaux's right eye and examine it; Grace seems to spot something unusual. Select the chair just behind the desk with your mouse cursor and select "move.". Grace will push the chair under the portrait. Stand on the chair and look again at the right eye on the portrait. You'll see an image of the Holy Grail.

Return to the desk and look to the left of the drawer you opened a moment ago. You'll spot a difficult-to-find button. Look on the desk leg to the left of the drawer and position the camera near the ground if you're having trouble finding the button. Use the mouse cursor on the button and select activate it. When you do, a set of laser beams will emit from the head statues positioned in five areas of the library.
