The man howls in agony as you barge past, and drops to one knee. You notice a very bad knife wound to his other leg, which is now gushing blood thanks to your ill manners.

Leave the painting where it is and continue your journey back to your hotel.

Pick up the painting and run like hell in the opposite direction.

You notice the sound of two pairs of running footsteps heading this way.
