Public Enemy Number Two by Antony Horowitz

Tim was staring at an object on a table only a couple of metres away from him. It was a Walt Disney alarm-clock with Mickey Mouse pointing at the time with his white-gloved hands: seven minutes to eleven. But I didn't think Walt Disney had been responsible for the rest of it. There were six sticks of dynamite attached to the clock. A yellow wire trailed away, leading to the door. A time bomb. It was set for eleven o'clock. Ring the doorbell and it would have gone off sooner. Tim,myself and Mickey Mouse world have been blown to smithereens. I forced myself to move.
