Joe looked up from his comic and lifted his eye patch. There was a white pony in the yard. It was harnessed to a cart, a flat cart, with a wooden chest on it. A man was sitting at a front corner of the cart, holding the reins. His face was creased. He wore a long coat and a floppy high-crowned hat, with hair straggling beneath, and a leather bag was slung from his shoulder across his hip. Joe Coppock squints at the world with his lazy eye. He reads his comics, collects birds' eggs and treasures his marbles, particularly his prized dobbers. When Treacle Walker appears off the Cheshire moor one day - a wanderer, a healer - an unlikely friendship is forged and the young boy is introduced to a world he could never have imagined.
