I caught Brenda herself in my house. It was late at night when I heard noises downstairs in the kitchen. I came down to find Her Majesty rifling through my cupboards. As soon as she saw me she darted away in to the hall. I grabbed a broom and chased after her. She ducked in to the living room, and I saw a strange green glow from the door. By the time I got in there she was gone. I reckon it was sone kind of alien technology teleporter. How else could an elderly monarch have escaped from a room with no other exits?
