'Tim Harford is peerless at making sense of a complicated world and our place within it. This is a book that all children should read' - Matthew Syed -> Did you know that a toy spaceship can teach you about inflation? -> Or that a pooping cow can show you how to invest your pocket money? -> And that even the greatest detectives have been fooled by fake news and dancing fairies? The world is often full of bamboozling headlines and numbers that don't add up. But don't panic. Within these pages you will transform into a Truth Detective, hunting down the truth about the world around you. You will meet heroic truth detectives, such as Florence Nightingale who started a revolution with a pie chart. You will encounter dastardly villains who have tried to trip us up with dodgy data and misinformation. And you will learn how being smart and savvy with numbers, will help you be smart and savvy about everything else in life too. So grab your detective cap, pick up your magnifying glass and start seeing the world like never before. A must read for curious kids from presenter of BBC Radio 4's "More or Less", Tim Harford and with wonderful illustrations to enjoy by Ollie Mann.
