This time I walked to the north end of the courtyard, where a massive tower rose. The stones of the tower, unlike the stones of the rest of the castle, were not whitewashed, but were so dark they were almost black. There were no windows for the first thirty feet. It was in this tower, according to the chaplain, that my predecessor had had his study.

A heavy oak door was the only way in. I tested the handle, but it wouldn’t open. With my eye to the crack along the doorjamb, I thought I saw a bolt on the inside. Delicately I tried a lifting spell on the bolt, or rather a sliding spell, to push it back in its track. Although I had to abandon the spell against the rain to give all my concentration to the bolt, my sliding spell actually worked. With only the slightest squeak, the bolt slid back, and I was able to pull the door open. Damp but delighted, I went in and closed the door behind me.

Inside it was completely black, except for tiny streaks of light around the door frame. I needed a light; I wondered if maybe I should start carrying a wizard’s staff. I could make a light, at least temporarily, but I needed something to attach it to. I found a piece of hay sticking to my trousers and tried that, but it made only a faint firefly glow. So I took off my belt and used the buckle. It was still not very bright, but it was serviceable, and since the design of the buckle was the moon and stars, it was rather dramatic. I wondered why I had not thought of making the buckle glow earlier and wondered if it would be possible to attach the light permanently.

Pleased with myself, I started up steep, uneven steps. It wasn’t until I had spiraled up at least halfway, I estimated, to the first window, that a sudden thought brought me to a halt. If the tower was empty, why had the door been bolted on the inside?
