“Suddenly I remembered Bruno. He must surely be around here somewhere, too. "Bruno!" I called out.
      I wasn't seriously expecting that I would be able to speak at all now that I had become a mouse, so I got the shock of my life when I heard my own voice, my own perfectly normal rather loud voice, coming out of my tiny mouth.
      It was wonderful. I was thrilled. I tried it again. "Bruno Jenkins, where are you?" I called out. "If you can hear me, give a shout!"
      My voice was exactly the same and just as loud as it had been when I was a boy.”
