‘Where is Patrick Spotter?’ The Japanese customer looked somewhat annoyed. She had been told that the staff of Heffers Children’s Bookshop in Cambridge were so knowledgeable that they could help with tracking down any book, even if the visitor didn’t know the title or author. We looked at each other in dismay. Was this an author we didn’t know? Then our manager appeared and courteously offered to take the lady round the shop: the first shelf they reached was Young Classics. ‘There!’ shouted the Japanese lady triumphantly. ‘Oh, Beatrix Potter!’ we smiled. She smiled; our reputation was intact and calm returned.
