A bland and not very imposing door is the only means by which one exits the tower. There is nothing special about the entrance - it is a simple stone arch. A broom and mop bucket are next to the door that leads to the outdoors.

I am an archer for the king's circle. I have killed many in battle. Peasants cannot do what I do.
Hail, groundskeeper, Hail servant.  How fare thee? I'm quite disturbed, archer. Among my duties is to transport the bodies away, but I'm afraid I have lost one near this tower entrance. Lost one what.  A bodie? Yes! The body of the wench from Fairside. She was on my cart, and now she has disappeared. I turned my back only for a minute, just to eat a small snack. What are these people dying from? Cholera, plague, any number of infections. But that's hardly the point. Where is her body? I've searched all around the entrance and I see nothing unusual. Have you tried climbing the tower for a better vantage? Indeed, that might be a solution to my troubles. You are a wise man, archer.  I spend much time int the towers, being an archer: Better to snipe the enemy! Yes, that makes good sense. I do have a slight suspicion. Perhaps she was not quite dead yet. Why is that? She was making some rumbling noises. You know, sometimes bodies do that, but hers seemed louder than usual.
