King's Escape

You were visiting Paris, sightseeing museums, theatres and restaurants. Walking through the city, you stumbled on a palace that intrigued you.
However, visits to the palace were forbidden. But that didn't stop you to sneak into the palace through the window. Meanwhile, a passer tipped off police that the burglary occurred. You don't have a lot of time. Find another way out of the palace, or you'll spend the rest of your journey in prison.
