Always face what you fear. Have just enough money, never too much, and some string. Even if it’s not your fault, it’s your responsibility. Witches deal with things. Never stand between two mirrors. Never cackle. Do what you must do. Never lie, but you don’t always have to be honest. Never wish. Especially don’t wish upon a star, which is astronomically stupid. Open your eyes, and then open your eyes again.

And then there were cats, thought Dog. He'd surprised the huge ginger cat from next door and had attempted to reduce it to cowering jelly by means of the usual glowing stare and deep-throated growl, which had always worked on the damned in the past. This time they had earned him a whack on the nose that had made his eyes water. Cats, Dog considered, were clearly a lot tougher than lost souls. He was looking forward to a further cat experiment, which he planned would consist of jumping around and yapping excitedly at it. It was a long shot, but it just might work.
