Tremors in the Blood

“A gripping and densely reported account of a little-known period of history, with implications for how we understand science to this day. I was hooked.” Sirin Kale, feature writer for The Guardian

“Katwala manages to bring history alive in this riveting delve back into the archives, placing you right at the heart of one of the most consequential – and controversial – inventions in criminal history.” Chris Stokel-Walker, author of TikTok Boom and YouTubers

“A gripping, forensically detailed account that reads more like a mystery than history.” Angela Saini, author of Superior and Inferior

“A wonderful book … tells the story of the lie detector, from the first, gripping murder case for which it was conceived, up to its use today in the justice system.” – Guardian

“Certainly demonstrates how easily the polygraph can be manipulated…deploys its twists and maintains suspense with some skill….Katwala tells his various tales with admirable lucidity….rich with colourful incidental detail.” Telegraph

“Tremors in the Blood, a cautionary tale about the limits of technology and the fallibility of humans, is as dramatic as any thriller”. Times

“With a cinematic narrative style that often reads more like a thriller than a work of history…Katwala charts how the (polygraph) machine tore apart the lives of the men who invented it, and explores how it led to the deaths of many more who failed to pass its test.” New Statesmen

“A thrilling, page-turning near-novelisation of the development of what we now know as the polygraph…Katwala’s meticulous archival research, centred around two high-profile US murder cases – those of Henry Wilkens and Joseph Rappaport – is worthy of any thriller.” The Spectator
