Brought to you by Penguin. WINNER OF THE 2014 CILIP CARNEGIE MEDAL. I can't believe I fell for it. It was still dark when I woke up this morning. As soon as my eyes opened I knew where I was. A low-ceilinged rectangular building made entirely of whitewashed concrete. There are six little rooms along the main corridor. There are no windows. No doors. The lift is the only way in or out. What's he going to do to me? What am I going to do? If I'm right, the lift will come down in five minutes. It did. Only this time it wasn't empty . . .
