Glen Duncan is a British author born in 1965 in Bolton, Lancashire, England to an Anglo-Indian family. He studied philosophy and literature at the universities of Lancaster and Exeter. In 1990 Duncan moved to London, where he worked as a bookseller for four years, writing in his spare time. In 1994 he visited India with his father (part roots odyssey, part research for a later work, The Bloodstone Papers) before continuing on to the United States, where he spent several months travelling the country by Amtrak train, writing much of what would become his first novel, Hope, published to critical acclaim on both sides of the Atlantic in 1997. Duncan lives in London. Recently, his 2002 novel I, Lucifer has had the film rights purchased, with actors such as Ewan Mcgregor, Jason Brescia, Jude Law, Vin Diesel, and Daniel Craig all being considered for roles in the forthcoming movie.
