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 by a rookie detective, a visionary police chief and a teenage magician with a showman's touch. They hoped it would make the justice system fairer - but it poisoned their lives, turned friends into bitter enemies and 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.
