Ken Follett burst into the book world in 1978 with Eye of the Needle, a taut and original thriller with a memorable woman character in the central role. The book won the Edgar award and became an outstanding film starring Kate Nelligan and Donald Sutherland.

He went on to write four more bestselling thrillers: Triple; The Key to Rebecca; The Man from St Petersburg; and Lie Down with Lions. Cliff Robertson and David Soul starred in the miniseries of The Key to Rebecca. In 1994 Timothy Dalton, Omar Sharif and Marg Helgenberger starred in the miniseries of Lie Down with Lions.

He also wrote On Wings of Eagles, the true story of how two employees of Ross Perot were rescued from Iran during the revolution of 1979. This book was made into a miniseries with Richard Crenna as Ross Perot and Burt Lancaster as Colonel "Bull" Simons.

He then surprised readers by radically changing course with The Pillars of the Earth, a novel about building a cathedral in the Middle Ages. Published in September 1989 to rave reviews, it was on the New York Times bestseller list for eighteen weeks. It also reached the No. 1 position on lists in Canada, Great Britain and Italy, and was on the German bestseller list for six years.

For a while he abandoned the straightforward spy genre, but his stories still had powerful narrative drive, strong women characters, and elements of suspense and intrigue. He followed Pillars with Night over Water, A Dangerous Fortune, and A Place Called Freedom.

Then he returned to the thriller. The Third Twin is a scorching suspense novel about a young woman scientist who stumbles over a secret experiment in genetic engineering. Miniseries rights were sold to CBS for $1,400,000, a record price for four hours of television. The series, starring Kelly McGillis and Larry Hagman, was broadcast in the USA in November 1997. In Publishing Trends' annual survey of international fiction bestsellers for 1997, The Third Twin was ranked No. 2 in the world, beaten only by John Grisham's The Partner.

The Hammer of Eden, another nail-biting contemporary suspense story, came in 1998. Code to Zero (2000), about brainwashing and rocket science in the fifties, went to No.1 on bestseller lists in the USA, German and Italy, and film rights were snapped up by Doug Wick, producer of Gladiator, in a seven-figure deal.

Ken returned to the WWII era with his next two novels: Jackdaws (2001), a World War II thriller about a group of women parachuted into France to destroy a vital telephone exchange – which won the won the Corine Prize for 2003– and Hornet Flight (2002), about a daring young Danish couple who escape to Britain from occupied Denmark in a rebuilt Hornet Moth biplane with vital information about German radar.

His latest novel, Whiteout (2004), is a contemporary thriller about the theft of a deadly virus from a research lab. Set in the remote Scottish Highlands over a stormy, snow-bound Christmas, Whiteout crackles with jealousies, distrust, sexual attraction, rivalries, hidden traitors and unexpected heroes.

His next project will be the long-awaited sequel to The Pillars of the Earth.

Ken's papers are held in a collection at Saginaw Valley State University in Michigan, United States. These include outlines, first drafts, notes and correspondence, original manuscripts and copies of early books now out of print. He has sold approximately ninety million books worldwide.
