John Le Carre's next book

From the International Herald Tribune:

John le Carré, the British writer of literary spy thrillers, has returned to a previous publisher for his forthcoming novel, "A Most Wanted Man." Le Carré has signed a one-book deal with Scribner, a unit of Simon & Schuster, for the United States rights to the novel, which will be simultaneously published in Britain (by Hodder & Stoughton) in October. Le Carré is leaving Little, Brown & Co., the publisher of his last two books, "The Mission Song" and "Absolute Friends," and returning to Scribner, which published "Single & Single" and "The Constant Gardener." The new novel is set in Germany and chronicles the fate of a Muslim man who moves to Hamburg to enroll in medical school but because of his murky background ends up being followed by both local and other Western intelligence agencies.
