Gran was right. There was a white spot at the back of her head where the comb had been. Poppy didn’t like it one bit. It reminded her of the story that Gran had told her about Suds. Was it some kind of mark you got before you vanished? She put the comb in a box and locked it. As she did so, she noticed something curious. The teeth on the comb had changed colour ever so slightly, as if they’d been dipped in greyish paint.
