Non-Fiction Biography
A thrilling account of the creation of the so-called lie
detector, exploring shocking murders and dramatic trials to
uncover the true nature of the polygraph. This tense true
crime story is perfect for fans of American
Predator and The Invention of Murder.
Late one evening in the summer of 1922, 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 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: beware what you believe.
