I blame what happened next on the door. The one right across the hall from me, a mere three feet away. I love doors. All of them, without exception. Doors lead to things and I’ve never met one I haven’t wanted to open. All the same, if that door hadn’t been so old and decorative, so decidedly closed, if a thread of light hadn’t positioned itself with such wretched temptation across its middle, highlighting the keyhole and its intriguing key, perhaps I might have stood a chance; remained twiddling my thumbs until Percy came to collect me. But it was and I didn’t; I maintain that I simply couldn’t. Sometimes, you can tell just by looking at a door there’s something interesting behind it.
