So in Geraldine McCaughrean's 1988 Carnegie Medal winning novel A Pack of Lies, Mrs. Povey's antique shop is basically a total and utter disaster due to her severely lacking business sense. For Mrs. Povey is so brutally honest about any flaws in the objects being sold that she often talks potential customers out of buying them, and also seriously undercharges when she finally does manage to make a sale, well, that is the case until the enigmatic MCC Berkshire arrives on the scene of A Pack of Lies, a mysterious helper who insists on working for nothing and who with his amazing stories and yarns about the for sale items at the store ends up making them massively and irresistibly appealing to and for potential customers. And indeed, Mrs. Povey and her daughter Ailsa, they are very quickly under the story-telling control of MCC Berkshire's skilled use of language, his irrefutable logic. But even though in A Pack of Lies, the elaborate tales MCC Berkshire tells about the shop items might well be elaborate fairy stories, might well be totally untruthful, yes, they do serve a wonderful and very practical purpose, as these accounts do verbally seduce potential buyers into making purchases, into buying the antique objects that erstwhile Mrs. Povery could either not sell or not sell with a decent amount of profit.
Now each chapter of A Pack of Lies basically features a short story about a particular object (an item for sale in Mrs. Povey's antique shop). And yes, Geraldine McCaughrean certainly does not show these tales as being just diversions, as each account is presented in a different literary style and all of them are utterly enthralling and fun. However, and to be honest, while my adult self has totally and utterly enjoyed the very different in style and genre stories of A Pack of Lies, the often surprising twists and turns that overlap and extend the stories-within-stories and that I have found A Pack of Lies humorous and written with delightful irony and finesse meta-fiction, I do have to admit that my inner child finds and considers A Pack of Lies a bit unorganised and lacking in textual coherence (so that my star rating of four stars A Pack of Lies certainly must come with the caveat that I for one tend to think that A Pack of Lies is more a story meant for adults and not so much for younger readers).
