Tom Knox is the pseudonym of British writer and journalist Sean Thomas. Born in Devon, England in 1963, he studied Philosophy at University College London. As a journalist he has written for the Times, the Daily Mail, the Spectator and the Guardian, chiefly on travel, politics and art. When he writes under the name of Tom Knox, he specialises in archaeological and religious thrillers. More recently he has written novels under the pseudonym S K Tremayne.
His first thriller, The Genesis Secret, focuses on the Neolithic archaeological site known as Gobekli Tepe in Turkey, which Knox visited as a journalist in 2006. The book speculates on the genetic and sociological origins of Christianity, Judaism and Islam, with particular attention to the trait of sacrifice. Noteworthy for several exceptionally gruesome episodes, it was an international bestseller, and has so far been translated into 21 languages. The novel provoked controversy when the German Archaeology Institute complained that both a newspaper article and the book were based on "a falsified version of an interview with [chief archaeologist] Klaus Schmidt", which they argued constituted "a distortion of the scientific work of the German Archaeological Institute".
His second thriller, The Marks of Cain was published in 2010. Centring on the little-known Cagot community who lived in the Basque Country, and the troubled history of the German empire in Namibia, it too was an international bestseller. In Germany, the ebook version, published under the title Cagot, was notable for its experimental use of interactivity and alternate reality games.
A third book, titled Bible of the Dead (or The Lost Goddess outside the United Kingdom) was published in March 2011 in the UK, and in the US in February 2012, and focuses on the Khmer Rouge, while taking in the cave paintings of France, and modern Chinese Communism.
In 2015, under the pseudonym S K Tremayne, he published a novel called The Ice Twins, about a London couple who lose a child, one of identical twins, and thereafter move to a remote island in Scotland. At this point the parents begin to suspect they have misidentified the surviving child. The Ice Twins became a Sunday Times Top Ten Bestseller in February 2015.
