Make your escape.

Not wanting to get cornered, you calmly encourage the horse forward.

A casual nod toward the guards when your cart emerges from the barn. Nothing untoward about this. You are, after all, the stable boy.

You guide the horse down to the main gate and wave at the guard there.

Moments later the portcullis is lifted and you push forward along the drawbridge, thankful that her last chances of calling for help will be masked by the clatter of the hooves and the cart's wheels over the wooden surface.

But it's not her cries for help you should have worried about.

Left alone in the back, the Princess eventually manages to wriggle free of the sack that covers her and kneels up above the side of the cart, her little gagged face just visible to the guard watching you leave.

"YOU, STOP!"

You hear the barked command well enough, and the ringing of the alarm bell seconds later.

Time to go!

You thrash the reins and the horse gallops on, into the night, leaving the castle behind.
