I first met my demon the morning that Mum said Dad had gone. ' My name is Alex. I'm ten years old. I like onions on toast & I can balance on the back legs of my chair for fourteen minutes. I can also see demons. My best friend is one. He likes Mozart table tennis & bread & butter pudding. My mum is sick. Ruen says he can help her. Only Ruen wants me to do something really bad. He wants me to kill someone.'
