'A wonderful book' - Guardian Truth, murder and the birth of the lie detector Henry Wilkens burst through the doors of the emergency room covered in his wife's blood. But was he a grieving husband, or a ruthless killer who'd conspired with bandits to have her murdered? To find out, the San Francisco police turned to technology, and a new machine that had just been invented in Berkeley by a rookie detective, a visionary police chief, and a teenage magician with a showman's touch. John Larson, Gus Vollmer and Leonarde Keeler hoped the lie detector would make the justice system fairer - but the flawed device soon grew too powerful for them to control. It poisoned their lives, turned fast friends into bitter enemies, and as it conquered America and the world, it transformed our relationship with the truth in ways that are still being felt. As new forms of lie detection gain momentum in the present day, Tremors in the Blood reveals the incredible truth behind the creation of the polygraph, through gripping true crime cases featuring explosive gunfights, shocking twists and high-stakes courtroom drama. Touching on psychology, technology and the science of the truth, Tremors in the Blood is a vibrant, atmospheric thriller, and a warning from history: be careful what you believe.

Sport changes your brain. The minds of elite athletes can pull off feats of anticipation and co-ordination that amateurs would find impossible. The athletic brain has been trained through hours and hours of practice - years of sweat and toil. But what if there were a shortcut to training your brain? Cognitive training tools offer the tantalising possibility of breaking the '10,000-hour rule'. Top-level athletes and teams are increasingly tapping into new knowledge of the brain to develop tools and techniques that can offer a shortcut to sporting success, or push the boundaries of performance beyond its current limits. Increasingly, these tools are becoming available to the ordinary amateur, revolutionising the ways in which anyone can improve their skills. Based on interviews with top athletes and the scientists working at the cutting edge of our knowledge, Amit Katwala provides a fascinating insight into the possibilities that are becoming open to us all. He takes us to see how Borussia Dortmund's 'Footbonaut' and touchscreen-based games in the NFL have been achieving excellent results. As with bestsellers such as The Chimp Paradoxand Bounce, by the end of this book, readers will look at sporting performance in a new light, and be able to apply these insights to their own lives.
