But nobody had seen Ellie that morning. No one had noticed her talking to a woman with red hair. No one had seen her walking with her towards Harlow Road. No one had seen Noelle Donnelly unlock the door of a small scruffy house with a flowering cherry tree outside and turn to Ellie and say, ‘Come on then, in you come.’ No one had seen Ellie walk through the door. No one had heard the door close behind her.
