Children’s books
Some of the great mysteries of life are explained: how shopkeepers used to mark their goods at £9.99 rather than £10 to force their staff to open the till and register the amount, rather than pocketing the tenner for themselves; Toblerone’s shape is inspired by the silhouette of Swiss mountain peaks; some of our best loved nursery rhymes are based on real-life events and characters.
The strength of the book lies in the rapid-fire question with short answer. The 10-page multi-layered answers are less successful.
