If you wish, you can quickly radio Grace for clues about killing demon (such as, "All demons have one vulnerable spot").

Use your talisman on the demon's face, then slice its throat with your dagger.

Use your mouse cursor and retreat from the creature. You can attempt to stab at the demon with your dagger. For a clue how to defeat the demon, watch when you attempt to stab in its head region. Notice how the demon protects its throat. Spot the sarcophagus in the back of the chamber.

The baby is safe! All is, once again, perfect in the world....

If you continue to retreat, you'll pass right next to it. Click on the sarcophagus and select "climb" from the verb menu. Watch the scene of Gabriel leaping onto the sarcophagus.

...except when Gabriel returns to his hotel room and finds Grace's note.

When the demon approaches, click on its head and select your talisman. The demon will cover his eyes and pull back his head. At that moment, click on the demon's throat and select your dagger. Gabriel will slice the demon's throat, killing both the creature and Montreaux.

Congratulations! You've solved the mystery and saved Prince James' son. Enjoy the final, bittersweet cutscene!
